+
+    Attributes
+    ----------
+    conf_nocache : bool
+        Set True to disable memory and file cache.
+        Default is False.
+
+    conf_noopt : bool
+        Set True to forces the optimization to be disabled,
+        in this case `CCompilerOpt` tends to generate all
+        expected headers in order to 'not' break the build.
+        Default is False.
+
+    conf_cache_factors : list
+        Add extra factors to the primary caching factors. The caching factors
+        are utilized to determine if there are changes had happened that
+        requires to discard the cache and re-updating it. The primary factors
+        are the arguments of `CCompilerOpt` and `CCompiler`'s properties(type, flags, etc).
+        Default is list of two items, containing the time of last modification
+        of `ccompiler_opt` and value of attribute "conf_noopt"
+
+    conf_tmp_path : str,
+        The path of temporary directory. Default is auto-created
+        temporary directory via ``tempfile.mkdtemp()``.
+
+    conf_check_path : str
+        The path of testing files. Each added CPU feature must have a
+        **C** source file contains at least one intrinsic or instruction that
+        related to this feature, so it can be tested against the compiler.
+        Default is ``./distutils/checks``.
+
+    conf_target_groups : dict
+        Extra tokens that can be reached from dispatch-able sources through
+        the special mark ``@targets``. Default is an empty dictionary.
+
+        **Notes**:
+            - case-insensitive for tokens and group names
+            - sign '#' must stick in the begin of group name and only within ``@targets``
+
+        **Example**:

+
+    conf_c_prefix_ : str
+        The prefix of internal C definitions. Default is ``"NPY__"``.
+
+    conf_cc_flags : dict
+        Nested dictionaries defining several compiler flags
+        that linked to some major functions, the main key
+        represent the compiler name and sub-keys represent
+        flags names. Default is already covers all supported
+        **C** compilers.
+
+        Sub-keys explained as follows:
+
+        "native": str or None
+            used by argument option `native`, to detect the current
+            machine support via the compiler.
+        "werror": str or None
+            utilized to treat warning as errors during testing CPU features
+            against the compiler and also for target's policy `$werror`
+            via dispatch-able sources.
+        "maxopt": str or None
+            utilized for target's policy '$maxopt' and the value should
+            contains the maximum acceptable optimization by the compiler.
+            e.g. in gcc ``'-O3'``
+
+        **Notes**:
+            * case-sensitive for compiler names and flags
+            * use space to separate multiple flags
+            * any flag will tested against the compiler and it will skipped
+              if it's not applicable.

+    conf_min_features : dict
+        A dictionary defines the used CPU features for

+    conf_features : dict
+        Nested dictionaries used for identifying the CPU features.
+        the primary key is represented as a feature name or group name
+        that gathers several features. Default values covers all
+        supported features but without the major options like "flags",
+        these undefined options handle it by method `conf_features_partial()`.
+        Default value is covers almost all CPU features for *X86*, *IBM/Power64*
+        and *ARM 7/8*.
+
+        Sub-keys explained as follows:
+
+        "implies" : str or list, optional,
+            List of CPU feature names to be implied by it,
+            the feature name must be defined within `conf_features`.
+            Default is None.
+
+        "flags": str or list, optional
+            List of compiler flags. Default is None.
+
+        "detect": str or list, optional
+            List of CPU feature names that required to be detected
+            in runtime. By default, its the feature name or features
+            in "group" if its specified.
+
+        "implies_detect": bool, optional
+            If True, all "detect" of implied features will be combined.
+            Default is True. see `feature_detect()`.
+
+        "group": str or list, optional
+            Same as "implies" but doesn't require the feature name to be
+            defined within `conf_features`.
+
+        "interest": int, required
+            a key for sorting CPU features
+
+        "headers": str or list, optional
+            intrinsics C header file
+
+        "disable": str, optional
+            force disable feature, the string value should contains the
+            reason of disabling.
+
+        "autovec": bool or None, optional
+            True or False to declare that CPU feature can be auto-vectorized
+            by the compiler.
+            By default(None), treated as True if the feature contains at
+            least one applicable flag. see `feature_can_autovec()`
+
+        "extra_checks": str or list, optional
+            Extra test case names for the CPU feature that need to be tested
+            against the compiler.
+
+            Each test case must have a C file named ``extra_xxxx.c``, where
+            ``xxxx`` is the case name in lower case, under 'conf_check_path'.
+            It should contain at least one intrinsic or function related to the test case.
+
+            If the compiler able to successfully compile the C file then `CCompilerOpt`
+            will add a C ``#define`` for it into the main dispatch header, e.g.
+            ``#define {conf_c_prefix}_XXXX`` where ``XXXX`` is the case name in upper case.
+
+        **NOTES**:
+            * space can be used as separator with options that supports "str or list"
+            * case-sensitive for all values and feature name must be in upper-case.
+            * if flags aren't applicable, its will skipped rather than disable the
+              CPU feature
+            * the CPU feature will disabled if the compiler fail to compile
+              the test file

+takes templated file .xxx.src and produces .xxx file  where .xxx is
+.i or .c or .h, using the following template rules
+
+/**begin repeat  -- on a line by itself marks the start of a repeated code
+                    segment
+/**end repeat**/ -- on a line by itself marks it's end
+
+After the /**begin repeat and before the */, all the named templates are placed
+these should all have the same number of replacements
+
+Repeat blocks can be nested, with each nested block labeled with its depth,
+i.e.
+/**begin repeat1
+ *....
+ */
+/**end repeat1**/
+
+When using nested loops, you can optionally exclude particular
+combinations of the variables using (inside the comment portion of the inner loop):
+
+ :exclude: var1=value1, var2=value2, ...
+
+This will exclude the pattern where var1 is value1 and var2 is value2 when
+the result is being generated.
+
+
+In the main body each replace will use one entry from the list of named replacements
+
+ Note that all #..# forms in a block must have the same number of
+   comma-separated entries.
+
+Example:
+
+    An input file containing
+
+        /**begin repeat

The file argument can also be a relative path in which case the + entire relative path will be installed into the package directory. + Finally, the file can be an absolute path name in which case the file + will be found at the absolute path name but installed to the package + path. + + This basic behavior can be augmented by passing a 2-tuple in as the + file argument. The first element of the tuple should specify the + relative path (under the package install directory) where the + remaining sequence of files should be installed to (it has nothing to + do with the file-names in the source distribution). The second element + of the tuple is the sequence of files that should be installed. The + files in this sequence can be filenames, relative paths, or absolute + paths. For absolute paths the file will be installed in the top-level + package installation directory (regardless of the first argument). + Filenames and relative path names will be installed in the package + install directory under the path name given as the first element of + the tuple. + + Rules for installation paths: + + #. file.txt -> (., file.txt)-> parent/file.txt + #. foo/file.txt -> (foo, foo/file.txt) -> parent/foo/file.txt + #. /foo/bar/file.txt -> (., /foo/bar/file.txt) -> parent/file.txt + #. ``*``.txt -> parent/a.txt, parent/b.txt + #. foo/``*``.txt`` -> parent/foo/a.txt, parent/foo/b.txt + #. ``*/*.txt`` -> (``*``, ``*``/``*``.txt) -> parent/c/a.txt, parent/d/b.txt + #. (sun, file.txt) -> parent/sun/file.txt + #. (sun, bar/file.txt) -> parent/sun/file.txt + #. (sun, /foo/bar/file.txt) -> parent/sun/file.txt + #. (sun, ``*``.txt) -> parent/sun/a.txt, parent/sun/b.txt + #. (sun, bar/``*``.txt) -> parent/sun/a.txt, parent/sun/b.txt + #. (sun/``*``, ``*``/``*``.txt) -> parent/sun/c/a.txt, parent/d/b.txt + + An additional feature is that the path to a data-file can actually be + a function that takes no arguments and returns the actual path(s) to + the data-files.

That is, the result +in each output array element only depends on the value in the corresponding +input array (or arrays) and on no other array elements. NumPy comes with a +large suite of ufuncs, and scipy extends that suite substantially. The simplest +example is the addition operator: :: + + >>> np.array([0,2,3,4]) + np.array([1,1,-1,2]) + array([1, 3, 2, 6]) + +The ufunc module lists all the available ufuncs in numpy. Documentation on +the specific ufuncs may be found in those modules. This documentation is +intended to address the more general aspects of ufuncs common to most of +them. All of the ufuncs that make use of Python operators (e.g., +, -, etc.) +have equivalent functions defined (e.g. add() for +) + +Type coercion +============= + +What happens when a binary operator (e.g., +,-,\\*,/, etc) deals with arrays of +two different types? What is the type of the result? Typically, the result is +the higher of the two types. For example: :: + + float32 + float64 -> float64 + int8 + int32 -> int32 + int16 + float32 -> float32 + float32 + complex64 -> complex64 + +There are some less obvious cases generally involving mixes of types +(e.g. uints, ints and floats) where equal bit sizes for each are not +capable of saving all the information in a different type of equivalent +bit size. Some examples are int32 vs float32 or uint32 vs int32. +Generally, the result is the higher type of larger size than both +(if available). So: :: + + int32 + float32 -> float64 + uint32 + int32 -> int64 + +Finally, the type coercion behavior when expressions involve Python +scalars is different than that seen for arrays. Since Python has a +limited number of types, combining a Python int with a dtype=np.int8 +array does not coerce to the higher type but instead, the type of the +array prevails. So the rules for Python scalars combined with arrays is +that the result will be that of the array equivalent the Python scalar +if the Python scalar is of a higher 'kind' than the array (e.g., float +vs. int), otherwise the resultant type will be that of the array. +For example: :: + + Python int + int8 -> int8 + Python float + int8 -> float64 + +ufunc methods +============= + +Binary ufuncs support 4 methods. + +**.reduce(arr)** applies the binary operator to elements of the array in + sequence. For example: :: + + >>> np.add.reduce(np.arange(10)) # adds all elements of array + 45 + +For multidimensional arrays, the first dimension is reduced by default: :: + + >>> np.add.reduce(np.arange(10).reshape(2,5)) + array([ 5, 7, 9, 11, 13]) + +The axis keyword can be used to specify different axes to reduce: :: + + >>> np.add.reduce(np.arange(10).reshape(2,5),axis=1) + array([10, 35]) + +**.accumulate(arr)** applies the binary operator and generates an +equivalently shaped array that includes the accumulated amount for each +element of the array. A couple examples: :: + + >>> np.add.accumulate(np.arange(10)) + array([ 0, 1, 3, 6, 10, 15, 21, 28, 36, 45]) + >>> np.multiply.accumulate(np.arange(1,9)) + array([ 1, 2, 6, 24, 120, 720, 5040, 40320]) + +The behavior for multidimensional arrays is the same as for .reduce(), +as is the use of the axis keyword). + +**.reduceat(arr,indices)** allows one to apply reduce to selected parts + of an array. It is a difficult method to understand. See the documentation + at: + +**.outer(arr1,arr2)** generates an outer operation on the two arrays arr1 and + arr2. It will work on multidimensional arrays (the shape of the result is + the concatenation of the two input shapes.: :: + + >>> np.multiply.outer(np.arange(3),np.arange(4)) + array([[0, 0, 0, 0], + [0, 1, 2, 3], + [0, 2, 4, 6]]) + +Output arguments +================ + +All ufuncs accept an optional output array. The array must be of the expected +output shape. Beware that if the type of the output array is of a different +(and lower) type than the output result, the results may be silently truncated +or otherwise corrupted in the downcast to the lower type. This usage is useful +when one wants to avoid creating large temporary arrays and instead allows one +to reuse the same array memory repeatedly (at the expense of not being able to +use more convenient operator notation in expressions). Note that when the +output argument is used, the ufunc still returns a reference to the result. + + >>> x = np.arange(2) + >>> np.add(np.arange(2, dtype=float), np.arange(2, dtype=float), x, + ... casting='unsafe') + array([0, 2]) + >>> x + array([0, 2]) + +and & or as ufuncs +================== + +Invariably people try to use the python 'and' and 'or' as logical operators +(and quite understandably). But these operators do not behave as normal +operators since Python treats these quite differently. They cannot be +overloaded with array equivalents. Thus using 'and' or 'or' with an array +results in an error. There are two alternatives: + + 1) use the ufunc functions logical_and() and logical_or(). + 2) use the bitwise operators & and \\|. The drawback of these is that if + the arguments to these operators are not boolean arrays, the result is + likely incorrect. On the other hand, most usages of logical_and and + logical_or are with boolean arrays. As long as one is careful, this is + a convenient way to apply these operators. + +""" diff --git a/Scripts_RSCM_sim_growth_n_climate_to_Yield/.venv/lib/python3.10/site-packages/numpy/f2py/cb_rules.py b/Scripts_RSCM_sim_growth_n_climate_to_Yield/.venv/lib/python3.10/site-packages/numpy/f2py/cb_rules.py new file mode 100644 index 0000000000000000000000000000000000000000..faf8dd4013018a3fd1cfc1afdf62104ed98b16b1 --- /dev/null +++ b/Scripts_RSCM_sim_growth_n_climate_to_Yield/.venv/lib/python3.10/site-packages/numpy/f2py/cb_rules.py @@ -0,0 +1,644 @@ +""" +Build call-back mechanism for f2py2e. + +Copyright 1999 -- 2011 Pearu Peterson all rights reserved. +Copyright 2011 -- present NumPy Developers. +Permission to use, modify, and distribute this software is given under the +terms of the NumPy License. + +NO WARRANTY IS EXPRESSED OR IMPLIED.

fftshift Shift zero-frequency component to center of spectrum. + ifftshift Inverse of fftshift. + + +Background information +---------------------- + +Fourier analysis is fundamentally a method for expressing a function as a +sum of periodic components, and for recovering the function from those +components. When both the function and its Fourier transform are +replaced with discretized counterparts, it is called the discrete Fourier +transform (DFT). The DFT has become a mainstay of numerical computing in +part because of a very fast algorithm for computing it, called the Fast +Fourier Transform (FFT), which was known to Gauss (1805) and was brought +to light in its current form by Cooley and Tukey [CT]_. Press et al. [NR]_ +provide an accessible introduction to Fourier analysis and its +applications. + +Because the discrete Fourier transform separates its input into +components that contribute at discrete frequencies, it has a great number +of applications in digital signal processing, e.g., for filtering, and in +this context the discretized input to the transform is customarily +referred to as a *signal*, which exists in the *time domain*. The output +is called a *spectrum* or *transform* and exists in the *frequency +domain*. + +Implementation details +---------------------- + +There are many ways to define the DFT, varying in the sign of the +exponent, normalization, etc. In this implementation, the DFT is defined +as + +.. math:: + A_k = \\sum_{m=0}^{n-1} a_m \\exp\\left\\{-2\\pi i{mk \\over n}\\right\\} + \\qquad k = 0,\\ldots,n-1. + +The DFT is in general defined for complex inputs and outputs, and a +single-frequency component at linear frequency :math:`f` is +represented by a complex exponential +:math:`a_m = \\exp\\{2\\pi i\\,f m\\Delta t\\}`, where :math:`\\Delta t` +is the sampling interval. + +The values in the result follow so-called "standard" order: If ``A = +fft(a, n)``, then ``A[0]`` contains the zero-frequency term (the sum of +the signal), which is always purely real for real inputs. Then ``A[1:n/2]`` +contains the positive-frequency terms, and ``A[n/2+1:]`` contains the +negative-frequency terms, in order of decreasingly negative frequency. +For an even number of input points, ``A[n/2]`` represents both positive and +negative Nyquist frequency, and is also purely real for real input. For +an odd number of input points, ``A[(n-1)/2]`` contains the largest positive +frequency, while ``A[(n+1)/2]`` contains the largest negative frequency. +The routine ``np.fft.fftfreq(n)`` returns an array giving the frequencies +of corresponding elements in the output. The routine +``np.fft.fftshift(A)`` shifts transforms and their frequencies to put the +zero-frequency components in the middle, and ``np.fft.ifftshift(A)`` undoes +that shift. + +When the input `a` is a time-domain signal and ``A = fft(a)``, ``np.abs(A)`` +is its amplitude spectrum and ``np.abs(A)**2`` is its power spectrum. +The phase spectrum is obtained by ``np.angle(A)``. + +The inverse DFT is defined as + +.. math:: + a_m = \\frac{1}{n}\\sum_{k=0}^{n-1}A_k\\exp\\left\\{2\\pi i{mk\\over n}\\right\\} + \\qquad m = 0,\\ldots,n-1. + +It differs from the forward transform by the sign of the exponential +argument and the default normalization by :math:`1/n`. + +Type Promotion +-------------- + +`numpy.fft` promotes ``float32`` and ``complex64`` arrays to ``float64`` and +``complex128`` arrays respectively. For an FFT implementation that does not +promote input arrays, see `scipy.fftpack`. + +Normalization +------------- + +The argument ``norm`` indicates which direction of the pair of direct/inverse +transforms is scaled and with what normalization factor. +The default normalization (``"backward"``) has the direct (forward) transforms +unscaled and the inverse (backward) transforms scaled by :math:`1/n`. It is +possible to obtain unitary transforms by setting the keyword argument ``norm`` +to ``"ortho"`` so that both direct and inverse transforms are scaled by +:math:`1/\\sqrt{n}`. Finally, setting the keyword argument ``norm`` to +``"forward"`` has the direct transforms scaled by :math:`1/n` and the inverse +transforms unscaled (i.e. exactly opposite to the default ``"backward"``). +`None` is an alias of the default option ``"backward"`` for backward +compatibility. + +Real and Hermitian transforms +----------------------------- + +When the input is purely real, its transform is Hermitian, i.e., the +component at frequency :math:`f_k` is the complex conjugate of the +component at frequency :math:`-f_k`, which means that for real +inputs there is no information in the negative frequency components that +is not already available from the positive frequency components. +The family of `rfft` functions is +designed to operate on real inputs, and exploits this symmetry by +computing only the positive frequency components, up to and including the +Nyquist frequency. Thus, ``n`` input points produce ``n/2+1`` complex +output points. The inverses of this family assumes the same symmetry of +its input, and for an output of ``n`` points uses ``n/2+1`` input points. + +Correspondingly, when the spectrum is purely real, the signal is +Hermitian. The `hfft` family of functions exploits this symmetry by +using ``n/2+1`` complex points in the input (time) domain for ``n`` real +points in the frequency domain. + +In higher dimensions, FFTs are used, e.g., for image analysis and +filtering. The computational efficiency of the FFT means that it can +also be a faster way to compute large convolutions, using the property +that a convolution in the time domain is equivalent to a point-by-point +multiplication in the frequency domain. + +Higher dimensions +----------------- + +In two dimensions, the DFT is defined as + +.. math:: + A_{kl} = \\sum_{m=0}^{M-1} \\sum_{n=0}^{N-1} + a_{mn}\\exp\\left\\{-2\\pi i \\left({mk\\over M}+{nl\\over N}\\right)\\right\\} + \\qquad k = 0, \\ldots, M-1;\\quad l = 0, \\ldots, N-1, + +which extends in the obvious way to higher dimensions, and the inverses +in higher dimensions also extend in the same way. + +References +---------- + +..

The format stores all +of the shape and dtype information necessary to reconstruct the array +correctly even on another machine with a different architecture. +The format is designed to be as simple as possible while achieving +its limited goals. + +The ``.npz`` format is the standard format for persisting *multiple* NumPy +arrays on disk. A ``.npz`` file is a zip file containing multiple ``.npy`` +files, one for each array. + +Capabilities +------------ + +- Can represent all NumPy arrays including nested record arrays and + object arrays. + +- Represents the data in its native binary form. + +- Supports Fortran-contiguous arrays directly. + +- Stores all of the necessary information to reconstruct the array + including shape and dtype on a machine of a different + architecture. Both little-endian and big-endian arrays are + supported, and a file with little-endian numbers will yield + a little-endian array on any machine reading the file. The + types are described in terms of their actual sizes. For example, + if a machine with a 64-bit C "long int" writes out an array with + "long ints", a reading machine with 32-bit C "long ints" will yield + an array with 64-bit integers. + +- Is straightforward to reverse engineer. Datasets often live longer than + the programs that created them. A competent developer should be + able to create a solution in their preferred programming language to + read most ``.npy`` files that they have been given without much + documentation. + +- Allows memory-mapping of the data. See `open_memmap`. + +- Can be read from a filelike stream object instead of an actual file. + +- Stores object arrays, i.e. arrays containing elements that are arbitrary + Python objects. Files with object arrays are not to be mmapable, but + can be read and written to disk. + +Limitations +----------- + +- Arbitrary subclasses of numpy.ndarray are not completely preserved. + Subclasses will be accepted for writing, but only the array data will + be written out. A regular numpy.ndarray object will be created + upon reading the file. + +.. warning:: + + Due to limitations in the interpretation of structured dtypes, dtypes + with fields with empty names will have the names replaced by 'f0', 'f1', + etc. Such arrays will not round-trip through the format entirely + accurately. The data is intact; only the field names will differ. We are + working on a fix for this. This fix will not require a change in the + file format. The arrays with such structures can still be saved and + restored, and the correct dtype may be restored by using the + ``loadedarray.view(correct_dtype)`` method. + +File extensions +--------------- + +We recommend using the ``.npy`` and ``.npz`` extensions for files saved +in this format. This is by no means a requirement; applications may wish +to use these file formats but use an extension specific to the +application. In the absence of an obvious alternative, however, +we suggest using ``.npy`` and ``.npz``. + +Version numbering +----------------- + +The version numbering of these formats is independent of NumPy version +numbering. If the format is upgraded, the code in `numpy.io` will still +be able to read and write Version 1.0 files. + +Format Version 1.0 +------------------ + +The first 6 bytes are a magic string: exactly ``\\x93NUMPY``. + +The next 1 byte is an unsigned byte: the major version number of the file +format, e.g. ``\\x01``. + +The next 1 byte is an unsigned byte: the minor version number of the file +format, e.g. ``\\x00``. Note: the version of the file format is not tied +to the version of the numpy package. + +The next 2 bytes form a little-endian unsigned short int: the length of +the header data HEADER_LEN. + +The next HEADER_LEN bytes form the header data describing the array's +format. It is an ASCII string which contains a Python literal expression +of a dictionary. It is terminated by a newline (``\\n``) and padded with +spaces (``\\x20``) to make the total of +``len(magic string) + 2 + len(length) + HEADER_LEN`` be evenly divisible +by 64 for alignment purposes. + +The dictionary contains three keys: + + "descr" : dtype.descr + An object that can be passed as an argument to the `numpy.dtype` + constructor to create the array's dtype. + "fortran_order" : bool + Whether the array data is Fortran-contiguous or not. Since + Fortran-contiguous arrays are a common form of non-C-contiguity, + we allow them to be written directly to disk for efficiency. + "shape" : tuple of int + The shape of the array. + +For repeatability and readability, the dictionary keys are sorted in +alphabetic order. This is for convenience only. A writer SHOULD implement +this if possible. A reader MUST NOT depend on this. + +Following the header comes the array data. If the dtype contains Python +objects (i.e. ``dtype.hasobject is True``), then the data is a Python +pickle of the array. Otherwise the data is the contiguous (either C- +or Fortran-, depending on ``fortran_order``) bytes of the array. +Consumers can figure out the number of bytes by multiplying the number +of elements given by the shape (noting that ``shape=()`` means there is +1 element) by ``dtype.itemsize``. + +Format Version 2.0 +------------------ + +The version 1.0 format only allowed the array header to have a total size of +65535 bytes. This can be exceeded by structured arrays with a large number of +columns. The version 2.0 format extends the header size to 4 GiB. +`numpy.save` will automatically save in 2.0 format if the data requires it, +else it will always use the more compatible 1.0 format. + +The description of the fourth element of the header therefore has become: +"The next 4 bytes form a little-endian unsigned int: the length of the header +data HEADER_LEN." + +Format Version 3.0 +------------------ + +This version replaces the ASCII string (which in practice was latin1) with +a utf8-encoded string, so supports structured types with any unicode field +names. + +Notes +----- +The ``.npy`` format, including motivation for creating it and a comparison of +alternatives, is described in the +:doc:`"npy-format" NEP `, however details have +evolved with time and this document is more current. + +""" +import io +import os +import pickle +import warnings + +import numpy +from numpy.lib._utils_impl import drop_metadata + + +__all__ = [] + +drop_metadata.__module__ = "numpy.lib.format" + +EXPECTED_KEYS = {'descr', 'fortran_order', 'shape'} +MAGIC_PREFIX = b'\x93NUMPY' +MAGIC_LEN = len(MAGIC_PREFIX) + 2 +ARRAY_ALIGN = 64 # plausible values are powers of 2 between 16 and 4096 +BUFFER_SIZE = 2**18 # size of buffer for reading npz files in bytes +# allow growth within the address space of a 64 bit machine along one axis +GROWTH_AXIS_MAX_DIGITS = 21 # = len(str(8*2**64-1)) hypothetical int1 dtype + +# difference between version 1.0 and 2.0 is a 4 byte (I) header length +# instead of 2 bytes (H) allowing storage of large structured arrays +_header_size_info = { + (1, 0): (' 255: + raise ValueError("major version must be 0 <= major < 256") + if minor < 0 or minor > 255: + raise ValueError("minor version must be 0 <= minor < 256") + return MAGIC_PREFIX + bytes([major, minor]) + +def read_magic(fp): + """ Read the magic string to get the version of the file format. + + Parameters + ---------- + fp : filelike object + + Returns + ------- + major : int + minor : int + """ + magic_str = _read_bytes(fp, MAGIC_LEN, "magic string") + if magic_str[:-2] != MAGIC_PREFIX: + msg = "the magic string is not correct; expected %r, got %r" + raise ValueError(msg % (MAGIC_PREFIX, magic_str[:-2])) + major, minor = magic_str[-2:] + return major, minor + + +def dtype_to_descr(dtype): + """ + Get a serializable descriptor from the dtype. + + The .descr attribute of a dtype object cannot be round-tripped through + the dtype() constructor.

This is the algorithm MATLAB uses [1]. + It also appears in *Numerical recipes* in the discussion of SVD solutions + for linear least squares [2]. + + This default threshold is designed to detect rank deficiency accounting + for the numerical errors of the SVD computation. Imagine that there + is a column in `A` that is an exact (in floating point) linear combination + of other columns in `A`. Computing the SVD on `A` will not produce + a singular value exactly equal to 0 in general: any difference of + the smallest SVD value from 0 will be caused by numerical imprecision + in the calculation of the SVD. Our threshold for small SVD values takes + this numerical imprecision into account, and the default threshold will + detect such numerical rank deficiency. The threshold may declare a matrix + `A` rank deficient even if the linear combination of some columns of `A` + is not exactly equal to another column of `A` but only numerically very + close to another column of `A`. + + We chose our default threshold because it is in wide use. Other thresholds + are possible. For example, elsewhere in the 2007 edition of *Numerical + recipes* there is an alternative threshold of ``S.max() * + np.finfo(A.dtype).eps / 2. * np.sqrt(m + n + 1.)``. The authors describe + this threshold as being based on "expected roundoff error" (p 71). + + The thresholds above deal with floating point roundoff error in the + calculation of the SVD. However, you may have more information about + the sources of error in `A` that would make you consider other tolerance + values to detect *effective* rank deficiency. The most useful measure + of the tolerance depends on the operations you intend to use on your + matrix. For example, if your data come from uncertain measurements with + uncertainties greater than floating point epsilon, choosing a tolerance + near that uncertainty may be preferable. The tolerance may be absolute + if the uncertainties are absolute rather than relative. + + References + ---------- + ..

Contents:: + +See http://www.scipy.org/scipy/numpy/wiki/MaskedArray (dead link) +for updates of this document. + + +History +------- + +As a regular user of MaskedArray, I (Pierre G.F. Gerard-Marchant) became +increasingly frustrated with the subclassing of masked arrays (even if +I can only blame my inexperience). I needed to develop a class of arrays +that could store some additional information along with numerical values, +while keeping the possibility for missing data (picture storing a series +of dates along with measurements, what would later become the `TimeSeries +Scikit `__ +(dead link). + +I started to implement such a class, but then quickly realized that +any additional information disappeared when processing these subarrays +(for example, adding a constant value to a subarray would erase its +dates). I ended up writing the equivalent of *numpy.core.ma* for my +particular class, ufuncs included. Everything went fine until I needed to +subclass my new class, when more problems showed up: some attributes of +the new subclass were lost during processing. I identified the culprit as +MaskedArray, which returns masked ndarrays when I expected masked +arrays of my class. I was preparing myself to rewrite *numpy.core.ma* +when I forced myself to learn how to subclass ndarrays. As I became more +familiar with the *__new__* and *__array_finalize__* methods, +I started to wonder why masked arrays were objects, and not ndarrays, +and whether it wouldn't be more convenient for subclassing if they did +behave like regular ndarrays. + +The new *maskedarray* is what I eventually come up with. The +main differences with the initial *numpy.core.ma* package are +that MaskedArray is now a subclass of *ndarray* and that the +*_data* section can now be any subclass of *ndarray*. Apart from a +couple of issues listed below, the behavior of the new MaskedArray +class reproduces the old one. Initially the *maskedarray* +implementation was marginally slower than *numpy.ma* in some areas, +but work is underway to speed it up; the expectation is that it can be +made substantially faster than the present *numpy.ma*. + + +Note that if the subclass has some special methods and +attributes, they are not propagated to the masked version: +this would require a modification of the *__getattribute__* +method (first trying *ndarray.__getattribute__*, then trying +*self._data.__getattribute__* if an exception is raised in the first +place), which really slows things down. + +Main differences +---------------- + + * The *_data* part of the masked array can be any subclass of ndarray (but not recarray, cf below). + * *fill_value* is now a property, not a function. + * in the majority of cases, the mask is forced to *nomask* when no value is actually masked. A notable exception is when a masked array (with no masked values) has just been unpickled. + * I got rid of the *share_mask* flag, I never understood its purpose. + * *put*, *putmask* and *take* now mimic the ndarray methods, to avoid unpleasant surprises. Moreover, *put* and *putmask* both update the mask when needed. * if *a* is a masked array, *bool(a)* raises a *ValueError*, as it does with ndarrays. + * in the same way, the comparison of two masked arrays is a masked array, not a boolean + * *filled(a)* returns an array of the same subclass as *a._data*, and no test is performed on whether it is contiguous or not. + * the mask is always printed, even if it's *nomask*, which makes things easy (for me at least) to remember that a masked array is used. + * *cumsum* works as if the *_data* array was filled with 0. The mask is preserved, but not updated. + * *cumprod* works as if the *_data* array was filled with 1. The mask is preserved, but not updated. + +New features +------------ + +This list is non-exhaustive... + + * the *mr_* function mimics *r_* for masked arrays. + * the *anom* method returns the anomalies (deviations from the average) + +Using the new package with numpy.core.ma +---------------------------------------- + +I tried to make sure that the new package can understand old masked +arrays. Unfortunately, there's no upward compatibility. + +For example: + +>>> import numpy.core.ma as old_ma +>>> import maskedarray as new_ma +>>> x = old_ma.array([1,2,3,4,5], mask=[0,0,1,0,0]) +>>> x +array(data = + [ 1 2 999999 4 5], + mask = + [False False True False False], + fill_value=999999) +>>> y = new_ma.array([1,2,3,4,5], mask=[0,0,1,0,0]) +>>> y +array(data = [1 2 -- 4 5], + mask = [False False True False False], + fill_value=999999) +>>> x==y +array(data = + [True True True True True], + mask = + [False False True False False], + fill_value=?) +>>> old_ma.getmask(x) == new_ma.getmask(x) +array([True, True, True, True, True]) +>>> old_ma.getmask(y) == new_ma.getmask(y) +array([True, True, False, True, True]) +>>> old_ma.getmask(y) +False + + +Using maskedarray with matplotlib +--------------------------------- + +Starting with matplotlib 0.91.2, the masked array importing will work with +the maskedarray branch) as well as with earlier versions. + +By default matplotlib still uses numpy.ma, but there is an rcParams setting +that you can use to select maskedarray instead. In the matplotlibrc file +you will find:: + + #maskedarray : False # True to use external maskedarray module + # instead of numpy.ma; this is a temporary # + setting for testing maskedarray. + + +Uncomment and set to True to select maskedarray everywhere. +Alternatively, you can test a script with maskedarray by using a +command-line option, e.g.:: + + python simple_plot.py --maskedarray + + +Masked records +-------------- + +Like *numpy.ma.core*, the *ndarray*-based implementation +of MaskedArray is limited when working with records: you can +mask any record of the array, but not a field in a record. If you +need this feature, you may want to give the *mrecords* package +a try (available in the *maskedarray* directory in the scipy +sandbox). This module defines a new class, *MaskedRecord*. An +instance of this class accepts a *recarray* as data, and uses two +masks: the *fieldmask* has as many entries as records in the array, +each entry with the same fields as a record, but of boolean types: +they indicate whether the field is masked or not; a record entry +is flagged as masked in the *mask* array if all the fields are +masked. A few examples in the file should give you an idea of what +can be done. Note that *mrecords* is still experimental... + +Optimizing maskedarray +---------------------- + +Should masked arrays be filled before processing or not? +-------------------------------------------------------- + +In the current implementation, most operations on masked arrays involve +the following steps: + + * the input arrays are filled + * the operation is performed on the filled arrays + * the mask is set for the results, from the combination of the input masks and the mask corresponding to the domain of the operation. + +For example, consider the division of two masked arrays:: + + import numpy + import maskedarray as ma + x = ma.array([1,2,3,4],mask=[1,0,0,0], dtype=numpy.float64) + y = ma.array([-1,0,1,2], mask=[0,0,0,1], dtype=numpy.float64) + +The division of x by y is then computed as:: + + d1 = x.filled(0) # d1 = array([0., 2., 3., 4.]) + d2 = y.filled(1) # array([-1., 0., 1., 1.]) + m = ma.mask_or(ma.getmask(x), ma.getmask(y)) # m = + array([True,False,False,True]) + dm = ma.divide.domain(d1,d2) # array([False, True, False, False]) + result = (d1/d2).view(MaskedArray) # masked_array([-0. inf, 3., 4.]) + result._mask = logical_or(m, dm) + +Note that a division by zero takes place. To avoid it, we can consider +to fill the input arrays, taking the domain mask into account, so that:: + + d1 = x._data.copy() # d1 = array([1., 2., 3., 4.]) + d2 = y._data.copy() # array([-1., 0., 1., 2.]) + dm = ma.divide.domain(d1,d2) # array([False, True, False, False]) + numpy.putmask(d2, dm, 1) # d2 = array([-1., 1., 1., 2.]) + m = ma.mask_or(ma.getmask(x), ma.getmask(y)) # m = + array([True,False,False,True]) + result = (d1/d2).view(MaskedArray) # masked_array([-1. 0., 3., 2.]) + result._mask = logical_or(m, dm) + +Note that the *.copy()* is required to avoid updating the inputs with +*putmask*. The *.filled()* method also involves a *.copy()*. + +A third possibility consists in avoid filling the arrays:: + + d1 = x._data # d1 = array([1., 2., 3., 4.]) + d2 = y._data # array([-1., 0., 1., 2.]) + dm = ma.divide.domain(d1,d2) # array([False, True, False, False]) + m = ma.mask_or(ma.getmask(x), ma.getmask(y)) # m = + array([True,False,False,True]) + result = (d1/d2).view(MaskedArray) # masked_array([-1. inf, 3., 2.]) + result._mask = logical_or(m, dm) + +Note that here again the division by zero takes place. + +A quick benchmark gives the following results: + + * *numpy.ma.divide* : 2.69 ms per loop + * classical division : 2.21 ms per loop + * division w/ prefilling : 2.34 ms per loop + * division w/o filling : 1.55 ms per loop + +So, is it worth filling the arrays beforehand ? Yes, if we are interested +in avoiding floating-point exceptions that may fill the result with infs +and nans. No, if we are only interested into speed... + + +Thanks +------ + +I'd like to thank Paul Dubois, Travis Oliphant and Sasha for the +original masked array package: without you, I would never have started +that (it might be argued that I shouldn't have anyway, but that's +another story...).

Trying to describe the full range of +possibilities statically would result in types that are not very +helpful. For that reason, the typed NumPy API is often stricter than +the runtime NumPy API. This section describes some notable +differences. + +ArrayLike +~~~~~~~~~ + +The `ArrayLike` type tries to avoid creating object arrays. For +example, + +.. code-block:: python + + >>> np.array(x**2 for x in range(10)) + array( at ...>, dtype=object) + +is valid NumPy code which will create a 0-dimensional object +array. Type checkers will complain about the above example when using +the NumPy types however. If you really intended to do the above, then +you can either use a ``# type: ignore`` comment: + +.. code-block:: python + + >>> np.array(x**2 for x in range(10)) # type: ignore + +or explicitly type the array like object as `~typing.Any`: + +.. code-block:: python + + >>> from typing import Any + >>> array_like: Any = (x**2 for x in range(10)) + >>> np.array(array_like) + array( at ...>, dtype=object) + +ndarray +~~~~~~~ + +It's possible to mutate the dtype of an array at runtime.

It was created in the Connectionist Artificial Intelligence Laboratory +(LIAC), which takes place at the Federal University of Rio Grande do Sul +(UFRGS), in Brazil. + +ARFF (Attribute-Relation File Format) is an file format specially created for +describe datasets which are commonly used for machine learning experiments and +software. This file format was created to be used in Weka, the best +representative software for machine learning automated experiments. + +An ARFF file can be divided into two sections: header and data. The Header +describes the metadata of the dataset, including a general description of the +dataset, its name and its attributes. The source below is an example of a +header section in a XOR dataset:: + + % + % XOR Dataset + % + % Created by Renato Pereira + % rppereira@inf.ufrgs.br + % http://inf.ufrgs.br/~rppereira + % + % + @RELATION XOR + + @ATTRIBUTE input1 REAL + @ATTRIBUTE input2 REAL + @ATTRIBUTE y REAL + +The Data section of an ARFF file describes the observations of the dataset, in +the case of XOR dataset:: + + @DATA + 0.0,0.0,0.0 + 0.0,1.0,1.0 + 1.0,0.0,1.0 + 1.0,1.0,0.0 + % + % + % + +Notice that several lines are starting with an ``%`` symbol, denoting a +comment, thus, lines with ``%`` at the beginning will be ignored, except by the +description part at the beginning of the file. The declarations ``@RELATION``, +``@ATTRIBUTE``, and ``@DATA`` are all case insensitive and obligatory. + +For more information and details about the ARFF file description, consult +http://www.cs.waikato.ac.nz/~ml/weka/arff.html + + +ARFF Files in Python +~~~~~~~~~~~~~~~~~~~~ + +This module uses built-ins python objects to represent a deserialized ARFF +file. A dictionary is used as the container of the data and metadata of ARFF, +and have the following keys: + +- **description**: (OPTIONAL) a string with the description of the dataset. +- **relation**: (OBLIGATORY) a string with the name of the dataset. +- **attributes**: (OBLIGATORY) a list of attributes with the following + template:: + + (attribute_name, attribute_type) + + the attribute_name is a string, and attribute_type must be an string + or a list of strings. +- **data**: (OBLIGATORY) a list of data instances. Each data instance must be + a list with values, depending on the attributes. + +The above keys must follow the case which were described, i.e., the keys are +case sensitive. The attribute type ``attribute_type`` must be one of these +strings (they are not case sensitive): ``NUMERIC``, ``INTEGER``, ``REAL`` or +``STRING``. For nominal attributes, the ``atribute_type`` must be a list of +strings. + +In this format, the XOR dataset presented above can be represented as a python +object as:: + + xor_dataset = { + 'description': 'XOR Dataset', + 'relation': 'XOR', + 'attributes': [ + ('input1', 'REAL'), + ('input2', 'REAL'), + ('y', 'REAL'), + ], + 'data': [ + [0.0, 0.0, 0.0], + [0.0, 1.0, 1.0], + [1.0, 0.0, 1.0], + [1.0, 1.0, 0.0] + ] + } + + +Features +~~~~~~~~ + +This module provides several features, including: + +- Read and write ARFF files using python built-in structures, such dictionaries + and lists; +- Supports `scipy.sparse.coo `_ + and lists of dictionaries as used by SVMLight +- Supports the following attribute types: NUMERIC, REAL, INTEGER, STRING, and + NOMINAL; +- Has an interface similar to other built-in modules such as ``json``, or + ``zipfile``; +- Supports read and write the descriptions of files; +- Supports missing values and names with spaces; +- Supports unicode values and names; +- Fully compatible with Python 2.7+, Python 3.5+, pypy and pypy3; +- Under `MIT License `_ + +''' +__author__ = 'Renato de Pontes Pereira, Matthias Feurer, Joel Nothman' +__author_email__ = ('renato.ppontes@gmail.com, ' + 'feurerm@informatik.uni-freiburg.de, ' + 'joel.nothman@gmail.com') +__version__ = '2.4.0' + +import re +import csv +from typing import TYPE_CHECKING +from typing import Optional, List, Dict, Any, Iterator, Union, Tuple + +# CONSTANTS =================================================================== +_SIMPLE_TYPES = ['NUMERIC', 'REAL', 'INTEGER', 'STRING'] + +_TK_DESCRIPTION = '%' +_TK_COMMENT = '%' +_TK_RELATION = '@RELATION' +_TK_ATTRIBUTE = '@ATTRIBUTE' +_TK_DATA = '@DATA' + +_RE_RELATION = re.compile(r'^([^\{\}%,\s]*|\".*\"|\'.*\')$', re.UNICODE) +_RE_ATTRIBUTE = re.compile(r'^(\".*\"|\'.*\'|[^\{\}%,\s]*)\s+(.+)$', re.UNICODE) +_RE_QUOTE_CHARS = re.compile(r'["\'\\\s%,\000-\031]', re.UNICODE) +_RE_ESCAPE_CHARS = re.compile(r'(?=["\'\\%])|[\n\r\t\000-\031]') +_RE_SPARSE_LINE = re.compile(r'^\s*\{.*\}\s*$', re.UNICODE) +_RE_NONTRIVIAL_DATA = re.compile('["\'{}\\s]', re.UNICODE) + +ArffDenseDataType = Iterator[List] +ArffSparseDataType = Tuple[List, ...] + + +if TYPE_CHECKING: + # typing_extensions is available when mypy is installed + from typing_extensions import TypedDict + + class ArffContainerType(TypedDict): + description: str + relation: str + attributes: List + data: Union[ArffDenseDataType, ArffSparseDataType] + +else: + ArffContainerType = Dict[str, Any] + + +def _build_re_values(): + quoted_re = r''' + " # open quote followed by zero or more of: + (?: + (?= len(conversors): + raise BadDataFormat(row) + # XXX: int 0 is used for implicit values, not '0' + values = [values[i] if i in values else 0 for i in + range(len(conversors))] + else: + if len(values) != len(conversors): + raise BadDataFormat(row) + + yield self._decode_values(values, conversors) + + @staticmethod + def _decode_values(values, conversors): + try: + values = [None if value is None else conversor(value) + for conversor, value + in zip(conversors, values)] + except ValueError as exc: + if 'float: ' in str(exc): + raise BadNumericalValue() + return values + + def encode_data(self, data, attributes): + '''(INTERNAL) Encodes a line of data. + + Data instances follow the csv format, i.e, attribute values are + delimited by commas.

+    """
+    Return the Laplacian of a directed graph.
+
+    Parameters
+    ----------
+    csgraph : array_like or sparse matrix, 2 dimensions
+        Compressed-sparse graph, with shape (N, N).
+    normed : bool, optional
+        If True, then compute symmetrically normalized Laplacian.
+        Default: False.
+    return_diag : bool, optional
+        If True, then also return an array related to vertex degrees.
+        Default: False.
+    use_out_degree : bool, optional
+        If True, then use out-degree instead of in-degree.
+        This distinction matters only if the graph is asymmetric.
+        Default: False.
+    copy : bool, optional
+        If False, then change `csgraph` in place if possible,
+        avoiding doubling the memory use.
+        Default: True, for backward compatibility.
+    form : 'array', or 'function', or 'lo'
+        Determines the format of the output Laplacian:
+
+        * 'array' is a numpy array;
+        * 'function' is a pointer to evaluating the Laplacian-vector
+          or Laplacian-matrix product;
+        * 'lo' results in the format of the `LinearOperator`.
+
+        Choosing 'function' or 'lo' always avoids doubling
+        the memory use, ignoring `copy` value.
+        Default: 'array', for backward compatibility.
+    dtype : None or one of numeric numpy dtypes, optional
+        The dtype of the output. If ``dtype=None``, the dtype of the
+        output matches the dtype of the input csgraph, except for
+        the case ``normed=True`` and integer-like csgraph, where
+        the output dtype is 'float' allowing accurate normalization,
+        but dramatically increasing the memory use.
+        Default: None, for backward compatibility.
+    symmetrized : bool, optional
+        If True, then the output Laplacian is symmetric/Hermitian.
+        The symmetrization is done by ``csgraph + csgraph.T.conj``
+        without dividing by 2 to preserve integer dtypes if possible
+        prior to the construction of the Laplacian.
+        The symmetrization will increase the memory footprint of
+        sparse matrices unless the sparsity pattern is symmetric or
+        `form` is 'function' or 'lo'.
+        Default: False, for backward compatibility.
+
+    Returns
+    -------
+    lap : ndarray, or sparse matrix, or `LinearOperator`
+        The N x N Laplacian of csgraph. It will be a NumPy array (dense)
+        if the input was dense, or a sparse matrix otherwise, or
+        the format of a function or `LinearOperator` if
+        `form` equals 'function' or 'lo', respectively.
+    diag : ndarray, optional
+        The length-N main diagonal of the Laplacian matrix.
+        For the normalized Laplacian, this is the array of square roots
+        of vertex degrees or 1 if the degree is zero.
+
+    Notes
+    -----
+    The Laplacian matrix of a graph is sometimes referred to as the
+    "Kirchhoff matrix" or just the "Laplacian", and is useful in many
+    parts of spectral graph theory.
+    In particular, the eigen-decomposition of the Laplacian can give
+    insight into many properties of the graph, e.g.,
+    is commonly used for spectral data embedding and clustering.
+
+    The constructed Laplacian doubles the memory use if ``copy=True`` and
+    ``form="array"`` which is the default.
+    Choosing ``copy=False`` has no effect unless ``form="array"``
+    or the matrix is sparse in the ``coo`` format, or dense array, except
+    for the integer input with ``normed=True`` that forces the float output.
+
+    Sparse input is reformatted into ``coo`` if ``form="array"``,
+    which is the default.
+
+    If the input adjacency matrix is not symmetric, the Laplacian is
+    also non-symmetric unless ``symmetrized=True`` is used.
+
+    Diagonal entries of the input adjacency matrix are ignored and
+    replaced with zeros for the purpose of normalization where ``normed=True``.
+    The normalization uses the inverse square roots of row-sums of the input
+    adjacency matrix, and thus may fail if the row-sums contain
+    negative or complex with a non-zero imaginary part values.
+
+    The normalization is symmetric, making the normalized Laplacian also
+    symmetric if the input csgraph was symmetric.

+
+    The non-symmetric graph
+
+    >>> G = np.arange(9).reshape(3, 3)
+    >>> G
+    array([[0, 1, 2],
+           [3, 4, 5],
+           [6, 7, 8]])
+
+    has different row- and column sums, resulting in two varieties
+    of the Laplacian matrix, using an in-degree, which is the default
+
+    >>> L_in_degree = csgraph.laplacian(G)
+    >>> L_in_degree
+    array([[ 9, -1, -2],
+           [-3,  8, -5],
+           [-6, -7,  7]])
+
+    or alternatively an out-degree
+
+    >>> L_out_degree = csgraph.laplacian(G, use_out_degree=True)
+    >>> L_out_degree
+    array([[ 3, -1, -2],
+           [-3,  8, -5],
+           [-6, -7, 13]])
+
+    Constructing a symmetric Laplacian matrix, one can add the two as
+
+    >>> L_in_degree + L_out_degree.T
+    array([[ 12,  -4,  -8],
+            [ -4,  16, -12],
+            [ -8, -12,  20]])
+
+    or use the ``symmetrized=True`` option
+
+    >>> csgraph.laplacian(G, symmetrized=True)
+    array([[ 12,  -4,  -8],
+           [ -4,  16, -12],
+           [ -8, -12,  20]])
+
+    that is equivalent to symmetrizing the original graph
+
+    >>> csgraph.laplacian(G + G.T)
+    array([[ 12,  -4,  -8],
+           [ -4,  16, -12],
+           [ -8, -12,  20]])
+
+    The goal of normalization is to make the non-zero diagonal entries
+    of the Laplacian matrix to be all unit, also scaling off-diagonal
+    entries correspondingly. The normalization can be done manually, e.g.,
+
+    >>> G = np.array([[0, 1, 1], [1, 0, 1], [1, 1, 0]])
+    >>> L, d = csgraph.laplacian(G, return_diag=True)
+    >>> L
+    array([[ 2, -1, -1],
+           [-1,  2, -1],
+           [-1, -1,  2]])
+    >>> d
+    array([2, 2, 2])
+    >>> scaling = np.sqrt(d)
+    >>> scaling
+    array([1.41421356, 1.41421356, 1.41421356])
+    >>> (1/scaling)*L*(1/scaling)
+    array([[ 1. , -0.5, -0.5],
+           [-0.5,  1. , -0.5],
+           [-0.5, -0.5,  1. ]])
+
+    Or using ``normed=True`` option
+
+    >>> L, d = csgraph.laplacian(G, return_diag=True, normed=True)
+    >>> L
+    array([[ 1. , -0.5, -0.5],
+           [-0.5,  1. , -0.5],
+           [-0.5, -0.5,  1. ]])
+
+    which now instead of the diagonal returns the scaling coefficients
+
+    >>> d
+    array([1.41421356, 1.41421356, 1.41421356])
+
+    Zero scaling coefficients are substituted with 1s, where scaling
+    has thus no effect, e.g.,
+
+    >>> G = np.array([[0, 0, 0], [0, 0, 1], [0, 1, 0]])
+    >>> G
+    array([[0, 0, 0],
+           [0, 0, 1],
+           [0, 1, 0]])
+    >>> L, d = csgraph.laplacian(G, return_diag=True, normed=True)
+    >>> L
+    array([[ 0., -0., -0.],
+           [-0.,  1., -1.],
+           [-0., -1.,  1.]])
+    >>> d
+    array([1., 1., 1.])
+
+    Only the symmetric normalization is implemented, resulting
+    in a symmetric Laplacian matrix if and only if its graph is symmetric
+    and has all non-negative degrees, like in the examples above.
+
+    The output Laplacian matrix is by default a dense array or a sparse matrix
+    inferring its shape, format, and dtype from the input graph matrix:
+
+    >>> G = np.array([[0, 1, 1], [1, 0, 1], [1, 1, 0]]).astype(np.float32)
+    >>> G
+    array([[0., 1., 1.],
+           [1., 0., 1.],
+           [1., 1., 0.]], dtype=float32)
+    >>> csgraph.laplacian(G)
+    array([[ 2., -1., -1.],
+           [-1.,  2., -1.],
+           [-1., -1.,  2.]], dtype=float32)
+
+    but can alternatively be generated matrix-free as a LinearOperator:
+
+    >>> L = csgraph.laplacian(G, form="lo")
+    >>> L
+    <3x3 _CustomLinearOperator with dtype=float32>
+    >>> L(np.eye(3))
+    array([[ 2., -1., -1.],
+           [-1.,  2., -1.],
+           [-1., -1.,  2.]])
+
+    or as a lambda-function:
+
+    >>> L = csgraph.laplacian(G, form="function")
+    >>> L
+    . at 0x0000012AE6F5A598>
+    >>> L(np.eye(3))
+    array([[ 2., -1., -1.],
+           [-1.,  2., -1.],
+           [-1., -1.,  2.]])
+
+    The Laplacian matrix is used for
+    spectral data clustering and embedding
+    as well as for spectral graph partitioning.
+    Our final example illustrates the latter
+    for a noisy directed linear graph.
+
+    >>> from scipy.sparse import diags, random
+    >>> from scipy.sparse.linalg import lobpcg
+
+    Create a directed linear graph with ``N=35`` vertices
+    using a sparse adjacency matrix ``G``:
+
+    >>> N = 35
+    >>> G = diags(np.ones(N-1), 1, format="csr")
+
+    Fix a random seed ``rng`` and add a random sparse noise to the graph ``G``:
+
+    >>> rng = np.random.default_rng()
+    >>> G += 1e-2 * random(N, N, density=0.1, random_state=rng)
+
+    Set initial approximations for eigenvectors:
+
+    >>> X = rng.random((N, 2))
+
+    The constant vector of ones is always a trivial eigenvector
+    of the non-normalized Laplacian to be filtered out:
+
+    >>> Y = np.ones((N, 1))
+
+    Alternating (1) the sign of the graph weights allows determining
+    labels for spectral max- and min- cuts in a single loop.
+    Since the graph is undirected, the option ``symmetrized=True``
+    must be used in the construction of the Laplacian.
+    The option ``normed=True`` cannot be used in (2) for the negative weights
+    here as the symmetric normalization evaluates square roots.
+    The option ``form="lo"`` in (2) is matrix-free, i.e., guarantees
+    a fixed memory footprint and read-only access to the graph.
+    Calling the eigenvalue solver ``lobpcg`` (3) computes the Fiedler vector
+    that determines the labels as the signs of its components in (5).
+    Since the sign in an eigenvector is not deterministic and can flip,
+    we fix the sign of the first component to be always +1 in (4).
+
+    >>> for cut in ["max", "min"]:
+    ...     G = -G  # 1.
+    ...     L = csgraph.laplacian(G, symmetrized=True, form="lo")  # 2.
+    ...     _, eves = lobpcg(L, X, Y=Y, largest=False, tol=1e-3)  # 3.
+    ...     eves *= np.sign(eves[0, 0])  # 4.
+    ...     print(cut + "-cut labels:\\n", 1 * (eves[:, 0]>0))  # 5.
+    max-cut labels:
+    [1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1]
+    min-cut labels:
+    [1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]
+
+    As anticipated for a (slightly noisy) linear graph,
+    the max-cut strips all the edges of the graph coloring all
+    odd vertices into one color and all even vertices into another one,
+    while the balanced min-cut partitions the graph
+    in the middle by deleting a single edge.
+    Both determined partitions are optimal.

+NumPy Array API compatibility library
+
+This is a small wrapper around NumPy, CuPy, JAX, sparse and others that are
+compatible with the Array API standard https://data-apis.org/array-api/latest/.
+See also NEP 47 https://numpy.org/neps/nep-0047-array-api-standard.html.
+
+Unlike array_api_strict, this is not a strict minimal implementation of the
+Array API, but rather just an extension of the main NumPy namespace with
+changes needed to be compliant with the Array API. See
+https://numpy.org/doc/stable/reference/array_api.html for a full list of
+changes. In particular, unlike array_api_strict, this package does not use a
+separate Array object, but rather just uses numpy.ndarray directly.
+
+Library authors using the Array API may wish to test against array_api_strict
+to ensure they are not using functionality outside of the standard, but prefer
+this implementation for the default when working with NumPy arrays.

+        Note that this function only returns data types that are defined by
+        the array API.
+
+        Parameters
+        ----------
+        device : str, optional
+            The device to get the data types for.
+        kind : str or tuple of str, optional
+            The kind of data types to return. If ``None``, all data types are
+            returned. If a string, only data types of that kind are returned.
+            If a tuple, a dictionary containing the union of the given kinds
+            is returned. The following kinds are supported:
+
+            - ``'bool'``: boolean data types (i.e., ``bool``).
+            - ``'signed integer'``: signed integer data types (i.e., ``int8``,
+              ``int16``, ``int32``, ``int64``).
+            - ``'unsigned integer'``: unsigned integer data types (i.e.,
+              ``uint8``, ``uint16``, ``uint32``, ``uint64``).
+            - ``'integral'``: integer data types. Shorthand for ``('signed
+              integer', 'unsigned integer')``.
+            - ``'real floating'``: real-valued floating-point data types
+              (i.e., ``float32``, ``float64``).
+            - ``'complex floating'``: complex floating-point data types (i.e.,
+              ``complex64``, ``complex128``).
+            - ``'numeric'``: numeric data types. Shorthand for ``('integral',
+              'real floating', 'complex floating')``.
+
+        Returns
+        -------
+        dtypes : dict
+            A dictionary mapping the names of data types to the corresponding
+            CuPy data types.

+    """Kernel ridge regression.
+
+    Kernel ridge regression (KRR) combines ridge regression (linear least
+    squares with l2-norm regularization) with the kernel trick. It thus
+    learns a linear function in the space induced by the respective kernel and
+    the data. For non-linear kernels, this corresponds to a non-linear
+    function in the original space.
+
+    The form of the model learned by KRR is identical to support vector
+    regression (SVR). However, different loss functions are used: KRR uses
+    squared error loss while support vector regression uses epsilon-insensitive
+    loss, both combined with l2 regularization. In contrast to SVR, fitting a
+    KRR model can be done in closed-form and is typically faster for
+    medium-sized datasets. On the other hand, the learned model is non-sparse
+    and thus slower than SVR, which learns a sparse model for epsilon > 0, at
+    prediction-time.
+
+    This estimator has built-in support for multi-variate regression
+    (i.e., when y is a 2d-array of shape [n_samples, n_targets]).
+
+    Read more in the :ref:`User Guide `.
+
+    Parameters
+    ----------
+    alpha : float or array-like of shape (n_targets,), default=1.0
+        Regularization strength; must be a positive float. Regularization
+        improves the conditioning of the problem and reduces the variance of
+        the estimates. Larger values specify stronger regularization.
+        Alpha corresponds to ``1 / (2C)`` in other linear models such as
+        :class:`~sklearn.linear_model.LogisticRegression` or
+        :class:`~sklearn.svm.LinearSVC`. If an array is passed, penalties are
+        assumed to be specific to the targets. Hence they must correspond in
+        number. See :ref:`ridge_regression` for formula.
+
+    kernel : str or callable, default="linear"
+        Kernel mapping used internally. This parameter is directly passed to
+        :class:`~sklearn.metrics.pairwise.pairwise_kernels`.
+        If `kernel` is a string, it must be one of the metrics
+        in `pairwise.PAIRWISE_KERNEL_FUNCTIONS` or "precomputed".
+        If `kernel` is "precomputed", X is assumed to be a kernel matrix.
+        Alternatively, if `kernel` is a callable function, it is called on
+        each pair of instances (rows) and the resulting value recorded. The
+        callable should take two rows from X as input and return the
+        corresponding kernel value as a single number. This means that
+        callables from :mod:`sklearn.metrics.pairwise` are not allowed, as
+        they operate on matrices, not single samples. Use the string
+        identifying the kernel instead.
+
+    gamma : float, default=None
+        Gamma parameter for the RBF, laplacian, polynomial, exponential chi2
+        and sigmoid kernels. Interpretation of the default value is left to
+        the kernel; see the documentation for sklearn.metrics.pairwise.
+        Ignored by other kernels.
+
+    degree : float, default=3
+        Degree of the polynomial kernel. Ignored by other kernels.
+
+    coef0 : float, default=1
+        Zero coefficient for polynomial and sigmoid kernels.
+        Ignored by other kernels.
+
+    kernel_params : dict, default=None
+        Additional parameters (keyword arguments) for kernel function passed
+        as callable object.
+
+    Attributes
+    ----------
+    dual_coef_ : ndarray of shape (n_samples,) or (n_samples, n_targets)
+        Representation of weight vector(s) in kernel space
+
+    X_fit_ : {ndarray, sparse matrix} of shape (n_samples, n_features)
+        Training data, which is also required for prediction. If
+        kernel == "precomputed" this is instead the precomputed
+        training matrix, of shape (n_samples, n_samples).
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`.
+
+        .. versionadded:: 0.24
+
+    feature_names_in_ : ndarray of shape (`n_features_in_`,)
+        Names of features seen during :term:`fit`. Defined only when `X`
+        has feature names that are all strings.
+
+        .. versionadded:: 1.0

+
+    In multilabel confusion matrix :math:`MCM`, the count of true negatives
+    is :math:`MCM_{:,0,0}`, false negatives is :math:`MCM_{:,1,0}`,
+    true positives is :math:`MCM_{:,1,1}` and false positives is
+    :math:`MCM_{:,0,1}`.
+
+    Multiclass data will be treated as if binarized under a one-vs-rest

+        Estimated targets as returned by a classifier.
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights.
+
+    labels : array-like of shape (n_classes,), default=None
+        A list of classes or column indices to select some (or to force

+
+    samplewise : bool, default=False
+        In the multilabel case, this calculates a confusion matrix per sample.
+
+    Returns
+    -------
+    multi_confusion : ndarray of shape (n_outputs, 2, 2)
+        A 2x2 confusion matrix corresponding to each output in the input.
+        When calculating class-wise multi_confusion (default), then
+        n_outputs = n_labels; when calculating sample-wise multi_confusion
+        (samplewise=True), n_outputs = n_samples. If ``labels`` is defined,

+        otherwise the results will be returned in sorted order by default.

+    The `multilabel_confusion_matrix` calculates class-wise or sample-wise

+    binarized under a one-vs-rest way; while
+    :func:`~sklearn.metrics.confusion_matrix` calculates one confusion matrix
+    for confusion between every two classes.

+
+    weights : {'linear', 'quadratic'}, default=None
+        Weighting type to calculate the score. `None` means not weighted;
+        "linear" means linear weighting; "quadratic" means quadratic weighting.

+    Returns
+    -------
+    kappa : float

+        If ``None``, the metrics for each class are returned. Otherwise, this

+            false negatives and false positives.
+        ``'macro'``:
+            Calculate metrics for each label, and find their unweighted

+    -----
+    When ``true positive + false positive + false negative == 0`` (i.e. a class

+    """Compute the F-beta score.
+
+    The F-beta score is the weighted harmonic mean of precision and recall,
+    reaching its optimal value at 1 and its worst value at 0.
+
+    The `beta` parameter represents the ratio of recall importance to
+    precision importance. `beta > 1` gives more weight to recall, while
+    `beta < 1` favors precision. For example, `beta = 2` makes recall twice
+    as important as precision, while `beta = 0.5` does the opposite.
+    Asymptotically, `beta -> +inf` considers only recall, and `beta -> 0`
+    only precision.
+
+    The formula for F-beta score is:
+
+    .. math::
+
+       F_\\beta = \\frac{(1 + \\beta^2) \\text{tp}}
+                        {(1 + \\beta^2) \\text{tp} + \\text{fp} + \\beta^2 \\text{fn}}
+
+    Where :math:`\\text{tp}` is the number of true positives, :math:`\\text{fp}` is the
+    number of false positives, and :math:`\\text{fn}` is the number of false negatives.
+
+    Support beyond term:`binary` targets is achieved by treating :term:`multiclass`
+    and :term:`multilabel` data as a collection of binary problems, one for each
+    label. For the :term:`binary` case, setting `average='binary'` will return
+    F-beta score for `pos_label`. If `average` is not `'binary'`, `pos_label` is
+    ignored and F-beta score for both classes are computed, then averaged or both
+    returned (when `average=None`). Similarly, for :term:`multiclass` and
+    :term:`multilabel` targets, F-beta score for all `labels` are either returned or
+    averaged depending on the `average` parameter. Use `labels` specify the set of
+    labels to calculate F-beta score for.

+
+    Parameters
+    ----------
+    y_true : 1d array-like, or label indicator array / sparse matrix
+        Ground truth (correct) target values.
+
+    y_pred : 1d array-like, or label indicator array / sparse matrix
+        Estimated targets as returned by a classifier.
+
+    beta : float
+        Determines the weight of recall in the combined score.
+
+    labels : array-like, default=None
+        The set of labels to include when `average != 'binary'`, and their
+        order if `average is None`. Labels present in the data can be
+        excluded, for example in multiclass classification to exclude a "negative
+        class". Labels not present in the data can be included and will be
+        "assigned" 0 samples. For multilabel targets, labels are column indices.
+        By default, all labels in `y_true` and `y_pred` are used in sorted order.
+
+        .. versionchanged:: 0.17
+           Parameter `labels` improved for multiclass problem.
+
+    pos_label : int, float, bool or str, default=1
+        The class to report if `average='binary'` and the data is binary,
+        otherwise this parameter is ignored.
+        For multiclass or multilabel targets, set `labels=[pos_label]` and
+        `average != 'binary'` to report metrics for one label only.
+
+    average : {'micro', 'macro', 'samples', 'weighted', 'binary'} or None, \
+            default='binary'
+        This parameter is required for multiclass/multilabel targets.
+        If ``None``, the metrics for each class are returned. Otherwise, this
+        determines the type of averaging performed on the data:
+
+        ``'binary'``:
+            Only report results for the class specified by ``pos_label``.
+            This is applicable only if targets (``y_{true,pred}``) are binary.
+        ``'micro'``:
+            Calculate metrics globally by counting the total true positives,
+            false negatives and false positives.
+        ``'macro'``:
+            Calculate metrics for each label, and find their unweighted
+            mean.  This does not take label imbalance into account.
+        ``'weighted'``:
+            Calculate metrics for each label, and find their average weighted
+            by support (the number of true instances for each label). This
+            alters 'macro' to account for label imbalance; it can result in an
+            F-score that is not between precision and recall.
+        ``'samples'``:
+            Calculate metrics for each instance, and find their average (only
+            meaningful for multilabel classification where this differs from
+            :func:`accuracy_score`).
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights.
+
+    zero_division : {"warn", 0.0, 1.0, np.nan}, default="warn"
+        Sets the value to return when there is a zero division, i.e. when all
+        predictions and labels are negative.
+
+        Notes:
+
+        - If set to "warn", this acts like 0, but a warning is also raised.
+        - If set to `np.nan`, such values will be excluded from the average.
+
+        .. versionadded:: 1.3
+           `np.nan` option was added.
+
+    Returns
+    -------
+    fbeta_score : float (if average is not None) or array of float, shape =\
+        [n_unique_labels]
+        F-beta score of the positive class in binary classification or weighted
+        average of the F-beta score of each class for the multiclass task.
+
+    See Also
+    --------
+    precision_recall_fscore_support : Compute the precision, recall, F-score,
+        and support.
+    multilabel_confusion_matrix : Compute a confusion matrix for each class or
+        sample.
+
+    Notes
+    -----
+    When ``true positive + false positive + false negative == 0``, f-score
+    returns 0.0 and raises ``UndefinedMetricWarning``. This behavior can be
+    modified by setting ``zero_division``.
+
+    F-beta score is not implemented as a named scorer that can be passed to
+    the `scoring` parameter of cross-validation tools directly: it requires to be
+    wrapped with :func:`make_scorer` so as to specify the value of `beta`. See
+    examples for details.

+    Notes
+    -----
+    When ``true positive + false positive == 0``, precision is undefined.
+    When ``true positive + false negative == 0``, recall is undefined. When
+    ``true positive + false negative + false positive == 0``, f-score is
+    undefined. In such cases, by default the metric will be set to 0, and
+    ``UndefinedMetricWarning`` will be raised. This behavior can be modified
+    with ``zero_division``.

+    """Compute binary classification positive and negative likelihood ratios.
+
+    The positive likelihood ratio is `LR+ = sensitivity / (1 - specificity)`
+    where the sensitivity or recall is the ratio `tp / (tp + fn)` and the
+    specificity is `tn / (tn + fp)`. The negative likelihood ratio is `LR- = (1
+    - sensitivity) / specificity`. Here `tp` is the number of true positives,
+    `fp` the number of false positives, `tn` is the number of true negatives and
+    `fn` the number of false negatives. Both class likelihood ratios can be used
+    to obtain post-test probabilities given a pre-test probability.
+
+    `LR+` ranges from 1.0 to infinity. A `LR+` of 1.0 indicates that the probability
+    of predicting the positive class is the same for samples belonging to either
+    class; therefore, the test is useless. The greater `LR+` is, the more a
+    positive prediction is likely to be a true positive when compared with the
+    pre-test probability. A value of `LR+` lower than 1.0 is invalid as it would
+    indicate that the odds of a sample being a true positive decrease with
+    respect to the pre-test odds.
+
+    `LR-` ranges from 0.0 to 1.0. The closer it is to 0.0, the lower the probability
+    of a given sample to be a false negative. A `LR-` of 1.0 means the test is
+    useless because the odds of having the condition did not change after the
+    test. A value of `LR-` greater than 1.0 invalidates the classifier as it
+    indicates an increase in the odds of a sample belonging to the positive
+    class after being classified as negative. This is the case when the
+    classifier systematically predicts the opposite of the true label.
+
+    A typical application in medicine is to identify the positive/negative class
+    to the presence/absence of a disease, respectively; the classifier being a
+    diagnostic test; the pre-test probability of an individual having the
+    disease can be the prevalence of such disease (proportion of a particular
+    population found to be affected by a medical condition); and the post-test
+    probabilities would be the probability that the condition is truly present
+    given a positive test result.

+    Parameters
+    ----------
+    y_true : 1d array-like, or label indicator array / sparse matrix
+        Ground truth (correct) target values.
+
+    y_pred : 1d array-like, or label indicator array / sparse matrix
+        Estimated targets as returned by a classifier.
+
+    labels : array-like, default=None
+        List of labels to index the matrix. This may be used to select the
+        positive and negative classes with the ordering `labels=[negative_class,
+        positive_class]`. If `None` is given, those that appear at least once in
+        `y_true` or `y_pred` are used in sorted order.
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights.
+
+    raise_warning : bool, default=True
+        Whether or not a case-specific warning message is raised when there is division
+        by zero.
+
+        .. deprecated:: 1.7
+            `raise_warning` was deprecated in version 1.7 and will be removed in 1.9,
+            when an :class:`~sklearn.exceptions.UndefinedMetricWarning` will always
+            raise in case of a division by zero.
+
+    replace_undefined_by : np.nan, 1.0, or dict, default=np.nan
+        Sets the return values for LR+ and LR- when there is a division by zero. Can
+        take the following values:
+
+        - `np.nan` to return `np.nan` for both `LR+` and `LR-`
+        - `1.0` to return the worst possible scores: `{"LR+": 1.0, "LR-": 1.0}`
+        - a dict in the format `{"LR+": value_1, "LR-": value_2}` where the values can
+          be non-negative floats, `np.inf` or `np.nan` in the range of the
+          likelihood ratios. For example, `{"LR+": 1.0, "LR-": 1.0}` can be used for
+          returning the worst scores, indicating a useless model, and `{"LR+": np.inf,
+          "LR-": 0.0}` can be used for returning the best scores, indicating a useful
+          model.
+
+        If a division by zero occurs, only the affected metric is replaced with the set
+        value; the other metric is calculated as usual.

+
+    Warns
+    -----
+    Raises :class:`~sklearn.exceptions.UndefinedMetricWarning` when `y_true` and

+
+        - The number of false positives is 0 and `raise_warning` is set to `True`
+          (default): positive likelihood ratio is undefined.
+        - The number of true negatives is 0 and `raise_warning` is set to `True`
+          (default): negative likelihood ratio is undefined.
+        - The sum of true positives and false negatives is 0 (no samples of the positive
+          class are present in `y_true`): both likelihood ratios are undefined.
+
+        For the first two cases, an undefined metric can be defined by setting the
+        `replace_undefined_by` param.

+    intuitively the ability of the classifier not to label as positive a sample
+    that is negative.
+
+    The best value is 1 and the worst value is 0.
+
+    Support beyond term:`binary` targets is achieved by treating :term:`multiclass`
+    and :term:`multilabel` data as a collection of binary problems, one for each
+    label. For the :term:`binary` case, setting `average='binary'` will return
+    precision for `pos_label`. If `average` is not `'binary'`, `pos_label` is ignored
+    and precision for both classes are computed, then averaged or both returned (when
+    `average=None`). Similarly, for :term:`multiclass` and :term:`multilabel` targets,
+    precision for all `labels` are either returned or averaged depending on the
+    `average` parameter. Use `labels` specify the set of labels to calculate precision
+    for.

+
+    Parameters
+    ----------
+    y_true : 1d array-like, or label indicator array / sparse matrix
+        Ground truth (correct) target values.
+
+    y_pred : 1d array-like, or label indicator array / sparse matrix
+        Estimated targets as returned by a classifier.
+
+    labels : array-like, default=None
+        The set of labels to include when `average != 'binary'`, and their
+        order if `average is None`. Labels present in the data can be
+        excluded, for example in multiclass classification to exclude a "negative
+        class". Labels not present in the data can be included and will be
+        "assigned" 0 samples. For multilabel targets, labels are column indices.
+        By default, all labels in `y_true` and `y_pred` are used in sorted order.
+
+        .. versionchanged:: 0.17
+           Parameter `labels` improved for multiclass problem.
+
+    pos_label : int, float, bool or str, default=1
+        The class to report if `average='binary'` and the data is binary,
+        otherwise this parameter is ignored.
+        For multiclass or multilabel targets, set `labels=[pos_label]` and
+        `average != 'binary'` to report metrics for one label only.
+
+    average : {'micro', 'macro', 'samples', 'weighted', 'binary'} or None, \
+            default='binary'
+        This parameter is required for multiclass/multilabel targets.
+        If ``None``, the metrics for each class are returned. Otherwise, this
+        determines the type of averaging performed on the data:
+
+        ``'binary'``:
+            Only report results for the class specified by ``pos_label``.
+            This is applicable only if targets (``y_{true,pred}``) are binary.
+        ``'micro'``:
+            Calculate metrics globally by counting the total true positives,
+            false negatives and false positives.
+        ``'macro'``:
+            Calculate metrics for each label, and find their unweighted
+            mean.  This does not take label imbalance into account.
+        ``'weighted'``:
+            Calculate metrics for each label, and find their average weighted
+            by support (the number of true instances for each label). This
+            alters 'macro' to account for label imbalance; it can result in an
+            F-score that is not between precision and recall.
+        ``'samples'``:
+            Calculate metrics for each instance, and find their average (only
+            meaningful for multilabel classification where this differs from
+            :func:`accuracy_score`).
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights.
+
+    zero_division : {"warn", 0.0, 1.0, np.nan}, default="warn"
+        Sets the value to return when there is a zero division.
+
+        Notes:
+
+        - If set to "warn", this acts like 0, but a warning is also raised.
+        - If set to `np.nan`, such values will be excluded from the average.
+
+        .. versionadded:: 1.3
+           `np.nan` option was added.
+
+    Returns
+    -------
+    precision : float (if average is not None) or array of float of shape \
+                (n_unique_labels,)
+        Precision of the positive class in binary classification or weighted
+        average of the precision of each class for the multiclass task.
+
+    See Also
+    --------
+    precision_recall_fscore_support : Compute precision, recall, F-measure and
+        support for each class.
+    recall_score :  Compute the ratio ``tp / (tp + fn)`` where ``tp`` is the
+        number of true positives and ``fn`` the number of false negatives.
+    PrecisionRecallDisplay.from_estimator : Plot precision-recall curve given
+        an estimator and some data.
+    PrecisionRecallDisplay.from_predictions : Plot precision-recall curve given
+        binary class predictions.
+    multilabel_confusion_matrix : Compute a confusion matrix for each class or
+        sample.
+
+    Notes
+    -----
+    When ``true positive + false positive == 0``, precision returns 0 and
+    raises ``UndefinedMetricWarning``. This behavior can be
+    modified with ``zero_division``.

+    Returns
+    -------
+    loss : float or int

+    zero_one_loss : Compute the Zero-one classification loss. By default, the
+        function will return the percentage of imperfectly predicted subsets.
+
+    Notes
+    -----
+    In multiclass classification, the Hamming loss corresponds to the Hamming
+    distance between ``y_true`` and ``y_pred`` which is equivalent to the
+    subset ``zero_one_loss`` function, when `normalize` parameter is set to
+    True.
+
+    In multilabel classification, the Hamming loss is different from the
+    subset zero-one loss. The zero-one loss considers the entire set of labels
+    for a given sample incorrect if it does not entirely match the true set of
+    labels. Hamming loss is more forgiving in that it penalizes only the
+    individual labels.
+
+    The Hamming loss is upperbounded by the subset zero-one loss, when
+    `normalize` parameter is set to True. It is always between 0 and 1,
+    lower being better.

+        When True, scale the Brier score by 1/2 to lie in the [0, 1] range instead
+        of the [0, 2] range. The default "auto" option implements the rescaling to

+    -------
+    score : float
+        Brier score loss.
+
+    Notes
+    -----
+
+    For :math:`N` observations labeled from :math:`C` possible classes, the Brier
+    score is defined as:
+
+    .. math::
+        \frac{1}{N}\sum_{i=1}^{N}\sum_{c=1}^{C}(y_{ic} - \hat{p}_{ic})^{2}
+
+    where :math:`y_{ic}` is 1 if observation `i` belongs to class `c`,
+    otherwise 0 and :math:`\hat{p}_{ic}` is the predicted probability for
+    observation `i` to belong to class `c`.
+    The Brier score then ranges between :math:`[0, 2]`.
+
+    In binary classification tasks the Brier score is usually divided by
+    two and then ranges between :math:`[0, 1]`. It can be alternatively
+    written as:
+
+    .. math::
+        \frac{1}{N}\sum_{i=1}^{N}(y_{i} - \hat{p}_{i})^{2}
+
+    where :math:`y_{i}` is the binary target and :math:`\hat{p}_{i}`
+    is the predicted probability of the positive class.

+    The `DistanceMetric` class provides a convenient way to compute pairwise distances
+    between samples. It supports various distance metrics, such as Euclidean distance,

+
+    The `pairwise` method can be used to compute pairwise distances between samples in
+    the input arrays. It returns a distance matrix representing the distances between
+    all pairs of samples.

+
+        1. The `data` arrays are passed using pointers to be able to support an
+        alternative representation of the CSR data structure for supporting
+        fused sparse-dense datasets pairs with minimum overhead.
+
+        See the explanations in `SparseDenseDatasetsPair.__init__`.
+
+        2. An alternative signature would be:

+            cdef {{INPUT_DTYPE_t}} dist_csr(
+                self,
+                const {{INPUT_DTYPE_t}}* x1_data,

+                const int32_t* x2_indices,
+            ) except -1 nogil:
+
+        Where callers would use slicing on the original CSR data and indices
+        memoryviews:
+
+            x1_start = X1_csr.indices_ptr[i]
+            x1_end   = X1_csr.indices_ptr[i+1]
+            x2_start = X2_csr.indices_ptr[j]
+            x2_end   = X2_csr.indices_ptr[j+1]

+                x2_indices[x2_start:x2_end],
+            )

+        Yet, slicing on memoryview slows down execution as it takes the GIL.
+        See: https://github.com/scikit-learn/scikit-learn/issues/17299

+            indicator matrix as a label.
+        ``'macro'``:
+            Calculate metrics for each label, and find their unweighted
+            mean.  This does not take label imbalance into account.
+        ``'weighted'``:
+            Calculate metrics for each label, and find their average, weighted
+            by support (the number of true instances for each label).
+        ``'samples'``:
+            Calculate metrics for each instance, and find their average.
+
+        Will be ignored when ``y_true`` is binary.
+
+    pos_label : int, float, bool or str, default=1
+        The label of the positive class. Only applied to binary ``y_true``.
+        For multilabel-indicator ``y_true``, ``pos_label`` is fixed to 1.
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights.
+
+    Returns
+    -------
+    average_precision : float
+        Average precision score.
+
+    See Also
+    --------
+    roc_auc_score : Compute the area under the ROC curve.
+    precision_recall_curve : Compute precision-recall pairs for different

+    Notes

+    ----------
+    y_true : ndarray of shape (n_samples,)
+        True binary labels. If labels are not either {-1, 1} or {0, 1}, then

+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights.
+
+    drop_intermediate : bool, default=False
+        Whether to drop thresholds where true positives (tp) do not change from
+        the previous or subsequent threshold. All points with the same tp value
+        have the same `fnr` and thus same y coordinate.

+        rate of predictions with score >= thresholds[i]. This is occasionally

+
+    thresholds : ndarray of shape (n_thresholds,)

+
+    Parameters
+    ----------
+    y_true : array-like of shape (n_samples,) or (n_samples, n_classes)
+        True labels or binary label indicators. The binary and multiclass cases
+        expect labels with shape (n_samples,) while the multilabel case expects
+        binary label indicators with shape (n_samples, n_classes).
+
+    y_score : array-like of shape (n_samples,) or (n_samples, n_classes)
+        Target scores.
+
+        * In the binary case, it corresponds to an array of shape
+          `(n_samples,)`. Both probability estimates and non-thresholded
+          decision values can be provided. The probability estimates correspond
+          to the **probability of the class with the greater label**,
+          i.e. `estimator.classes_[1]` and thus
+          `estimator.predict_proba(X, y)[:, 1]`. The decision values
+          corresponds to the output of `estimator.decision_function(X, y)`.
+          See more information in the :ref:`User guide `;
+        * In the multiclass case, it corresponds to an array of shape
+          `(n_samples, n_classes)` of probability estimates provided by the
+          `predict_proba` method. The probability estimates **must**
+          sum to 1 across the possible classes. In addition, the order of the
+          class scores must correspond to the order of ``labels``,
+          if provided, or else to the numerical or lexicographical order of
+          the labels in ``y_true``. See more information in the
+          :ref:`User guide `;
+        * In the multilabel case, it corresponds to an array of shape
+          `(n_samples, n_classes)`. Probability estimates are provided by the
+          `predict_proba` method and the non-thresholded decision values by
+          the `decision_function` method. The probability estimates correspond
+          to the **probability of the class with the greater label for each
+          output** of the classifier. See more information in the
+          :ref:`User guide `.
+
+    average : {'micro', 'macro', 'samples', 'weighted'} or None, \
+            default='macro'
+        If ``None``, the scores for each class are returned.
+        Otherwise, this determines the type of averaging performed on the data.
+        Note: multiclass ROC AUC currently only handles the 'macro' and
+        'weighted' averages. For multiclass targets, `average=None` is only
+        implemented for `multi_class='ovr'` and `average='micro'` is only
+        implemented for `multi_class='ovr'`.
+
+        ``'micro'``:
+            Calculate metrics globally by considering each element of the label
+            indicator matrix as a label.
+        ``'macro'``:
+            Calculate metrics for each label, and find their unweighted
+            mean.  This does not take label imbalance into account.
+        ``'weighted'``:
+            Calculate metrics for each label, and find their average, weighted
+            by support (the number of true instances for each label).
+        ``'samples'``:
+            Calculate metrics for each instance, and find their average.
+
+        Will be ignored when ``y_true`` is binary.
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights.
+
+    max_fpr : float > 0 and <= 1, default=None
+        If not ``None``, the standardized partial AUC [2]_ over the range
+        [0, max_fpr] is returned. For the multiclass case, ``max_fpr``,
+        should be either equal to ``None`` or ``1.0`` as AUC ROC partial
+        computation currently is not supported for multiclass.
+
+    multi_class : {'raise', 'ovr', 'ovo'}, default='raise'
+        Only used for multiclass targets. Determines the type of configuration
+        to use. The default value raises an error, so either
+        ``'ovr'`` or ``'ovo'`` must be passed explicitly.
+
+        ``'ovr'``:
+            Stands for One-vs-rest. Computes the AUC of each class
+            against the rest [3]_ [4]_. This
+            treats the multiclass case in the same way as the multilabel case.
+            Sensitive to class imbalance even when ``average == 'macro'``,
+            because class imbalance affects the composition of each of the
+            'rest' groupings.
+        ``'ovo'``:
+            Stands for One-vs-one. Computes the average AUC of all
+            possible pairwise combinations of classes [5]_.
+            Insensitive to class imbalance when
+            ``average == 'macro'``.
+
+    labels : array-like of shape (n_classes,), default=None
+        Only used for multiclass targets. List of labels that index the
+        classes in ``y_score``. If ``None``, the numerical or lexicographical
+        order of the labels in ``y_true`` is used.
+
+    Returns
+    -------
+    auc : float
+        Area Under the Curve score.
+
+    See Also
+    --------
+    average_precision_score : Area under the precision-recall curve.

+
+    Notes
+    -----
+    The Gini Coefficient is a summary measure of the ranking ability of binary
+    classifiers. It is expressed using the area under of the ROC as follows:
+
+    G = 2 * AUC - 1
+
+    Where G is the Gini coefficient and AUC is the ROC-AUC score. This normalisation
+    will ensure that random guessing will yield a score of 0 in expectation, and it is
+    upper bounded by 1.

+
+    Read more in the :ref:`User Guide `
+
+    Parameters
+    ----------
+    y_true : array-like of shape (n_samples,)
+        True labels.
+
+    y_score : array-like of shape (n_samples,) or (n_samples, n_classes)
+        Target scores. These can be either probability estimates or
+        non-thresholded decision values (as returned by
+        :term:`decision_function` on some classifiers).
+        The binary case expects scores with shape (n_samples,) while the
+        multiclass case expects scores with shape (n_samples, n_classes).
+        In the multiclass case, the order of the class scores must
+        correspond to the order of ``labels``, if provided, or else to
+        the numerical or lexicographical order of the labels in ``y_true``.
+        If ``y_true`` does not contain all the labels, ``labels`` must be
+        provided.
+
+    k : int, default=2
+        Number of most likely outcomes considered to find the correct label.
+
+    normalize : bool, default=True
+        If `True`, return the fraction of correctly classified samples.
+        Otherwise, return the number of correctly classified samples.
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Sample weights. If `None`, all samples are given the same weight.
+
+    labels : array-like of shape (n_classes,), default=None
+        Multiclass only. List of labels that index the classes in ``y_score``.
+        If ``None``, the numerical or lexicographical order of the labels in
+        ``y_true`` is used. If ``y_true`` does not contain all the labels,
+        ``labels`` must be provided.
+
+    Returns
+    -------
+    score : float
+        The top-k accuracy score. The best performance is 1 with
+        `normalize == True` and the number of samples with
+        `normalize == False`.
+
+    See Also
+    --------
+    accuracy_score : Compute the accuracy score. By default, the function will
+        return the fraction of correct predictions divided by the total number
+        of predictions.
+
+    Notes
+    -----
+    In cases where two or more labels are assigned equal predicted scores,
+    the labels with the highest indices will be chosen first. This might
+    impact the result if the correct label falls after the threshold because
+    of that.

+        which the model has the largest likelihood or lower bound. Within each
+        trial, the method iterates between E-step and M-step for ``max_iter``
+        times until the change of likelihood or lower bound is less than
+        ``tol``, otherwise, a ``ConvergenceWarning`` is raised.
+        If ``warm_start`` is ``True``, then ``n_init`` is ignored and a single
+        initialization is performed upon the first call. Upon consecutive
+        calls, training starts where it left off.

+class BayesianGaussianMixture(BaseMixture):
+    """Variational Bayesian estimation of a Gaussian mixture.
+
+    This class allows to infer an approximate posterior distribution over the
+    parameters of a Gaussian mixture distribution. The effective number of
+    components can be inferred from the data.
+
+    This class implements two types of prior for the weights distribution: a
+    finite mixture model with Dirichlet distribution and an infinite mixture
+    model with the Dirichlet Process. In practice Dirichlet Process inference
+    algorithm is approximated and uses a truncated distribution with a fixed
+    maximum number of components (called the Stick-breaking representation).
+    The number of components actually used almost always depends on the data.
+
+    .. versionadded:: 0.18
+
+    Read more in the :ref:`User Guide `.
+
+    Parameters
+    ----------
+    n_components : int, default=1
+        The number of mixture components. Depending on the data and the value
+        of the `weight_concentration_prior` the model can decide to not use
+        all the components by setting some component `weights_` to values very
+        close to zero. The number of effective components is therefore smaller
+        than n_components.
+
+    covariance_type : {'full', 'tied', 'diag', 'spherical'}, default='full'
+        String describing the type of covariance parameters to use.
+        Must be one of:
+
+        - 'full' (each component has its own general covariance matrix),
+        - 'tied' (all components share the same general covariance matrix),
+        - 'diag' (each component has its own diagonal covariance matrix),
+        - 'spherical' (each component has its own single variance).
+
+    tol : float, default=1e-3
+        The convergence threshold. EM iterations will stop when the
+        lower bound average gain on the likelihood (of the training data with
+        respect to the model) is below this threshold.
+
+    reg_covar : float, default=1e-6
+        Non-negative regularization added to the diagonal of covariance.
+        Allows to assure that the covariance matrices are all positive.
+
+    max_iter : int, default=100
+        The number of EM iterations to perform.
+
+    n_init : int, default=1
+        The number of initializations to perform. The result with the highest
+        lower bound value on the likelihood is kept.
+
+    init_params : {'kmeans', 'k-means++', 'random', 'random_from_data'}, \
+    default='kmeans'
+        The method used to initialize the weights, the means and the
+        covariances. String must be one of:
+
+        - 'kmeans': responsibilities are initialized using kmeans.
+        - 'k-means++': use the k-means++ method to initialize.
+        - 'random': responsibilities are initialized randomly.
+        - 'random_from_data': initial means are randomly selected data points.
+
+        .. versionchanged:: v1.1
+            `init_params` now accepts 'random_from_data' and 'k-means++' as
+            initialization methods.
+
+    weight_concentration_prior_type : {'dirichlet_process', 'dirichlet_distribution'}, \
+            default='dirichlet_process'
+        String describing the type of the weight concentration prior.
+
+    weight_concentration_prior : float or None, default=None
+        The dirichlet concentration of each component on the weight
+        distribution (Dirichlet). This is commonly called gamma in the
+        literature. The higher concentration puts more mass in
+        the center and will lead to more components being active, while a lower
+        concentration parameter will lead to more mass at the edge of the
+        mixture weights simplex. The value of the parameter must be greater
+        than 0. If it is None, it's set to ``1. / n_components``.
+
+    mean_precision_prior : float or None, default=None
+        The precision prior on the mean distribution (Gaussian).
+        Controls the extent of where means can be placed. Larger
+        values concentrate the cluster means around `mean_prior`.
+        The value of the parameter must be greater than 0.
+        If it is None, it is set to 1.
+
+    mean_prior : array-like, shape (n_features,), default=None
+        The prior on the mean distribution (Gaussian).
+        If it is None, it is set to the mean of X.
+
+    degrees_of_freedom_prior : float or None, default=None
+        The prior of the number of degrees of freedom on the covariance
+        distributions (Wishart). If it is None, it's set to `n_features`.
+
+    covariance_prior : float or array-like, default=None
+        The prior on the covariance distribution (Wishart).
+        If it is None, the emiprical covariance prior is initialized using the
+        covariance of X. The shape depends on `covariance_type`::
+
+                (n_features, n_features) if 'full',
+                (n_features, n_features) if 'tied',

+                float                    if 'spherical'
+
+    random_state : int, RandomState instance or None, default=None
+        Controls the random seed given to the method chosen to initialize the
+        parameters (see `init_params`).
+        In addition, it controls the generation of random samples from the
+        fitted distribution (see the method `sample`).
+        Pass an int for reproducible output across multiple function calls.
+        See :term:`Glossary `.
+
+    warm_start : bool, default=False
+        If 'warm_start' is True, the solution of the last fitting is used as
+        initialization for the next call of fit(). This can speed up
+        convergence when fit is called several times on similar problems.
+        See :term:`the Glossary `.
+
+    verbose : int, default=0
+        Enable verbose output. If 1 then it prints the current
+        initialization and each iteration step. If greater than 1 then
+        it prints also the log probability and the time needed
+        for each step.
+
+    verbose_interval : int, default=10
+        Number of iteration done before the next print.
+

+
+    precisions_ : array-like
+        The precision matrices for each component in the mixture. A precision
+        matrix is the inverse of a covariance matrix. A covariance matrix is
+        symmetric positive definite so the mixture of Gaussian can be
+        equivalently parameterized by the precision matrices. Storing the
+        precision matrices instead of the covariance matrices makes it more
+        efficient to compute the log-likelihood of new samples at test time.

+        component. A precision matrix is the inverse of a covariance matrix.
+        A covariance matrix is symmetric positive definite so the mixture of
+        Gaussian can be equivalently parameterized by the precision matrices.
+        Storing the precision matrices instead of the covariance matrices makes

+            float          if 'dirichlet_distribution' (Dirichlet parameters).
+
+        The higher concentration puts more mass in

+    the $UU^T$ factorization of the precision matrix for each Gaussian component, where
+    $U$ is an upper-triangular matrix.
+
+    In order to use the Cholesky decomposition to get $UU^T$, the precision matrix

+    can be done by applying a similarity transformation with an exchange matrix $J$,

+    particular, the Cholesky decomposition of the transformed precision matrix is

+    and $J=J^{-1}=J^T$, the `precisions_cholesky_` for each Gaussian component can be

+    ----------
+    weights_ : array-like of shape (n_components,)
+        The weights of each mixture components.
+
+    means_ : array-like of shape (n_components, n_features)
+        The mean of each mixture component.
+
+    covariances_ : array-like
+        The covariance of each mixture component.
+        The shape depends on `covariance_type`::
+
+            (n_components,)                        if 'spherical',

+
+        For an example of using covariances, refer to

+
+    precisions_ : array-like
+        The precision matrices for each component in the mixture. A precision
+        matrix is the inverse of a covariance matrix. A covariance matrix is
+        symmetric positive definite so the mixture of Gaussian can be
+        equivalently parameterized by the precision matrices. Storing the
+        precision matrices instead of the covariance matrices makes it more
+        efficient to compute the log-likelihood of new samples at test time.

+
+    precisions_cholesky_ : array-like
+        The cholesky decomposition of the precision matrices of each mixture
+        component. A precision matrix is the inverse of a covariance matrix.

+            (n_components, n_features, n_features) if 'full'
+
+    converged_ : bool
+        True when convergence of the best fit of EM was reached, False otherwise.
+
+    n_iter_ : int
+        Number of step used by the best fit of EM to reach the convergence.
+
+    lower_bound_ : float
+        Lower bound value on the log-likelihood (of the training data with
+        respect to the model) of the best fit of EM.
+
+    lower_bounds_ : array-like of shape (`n_iter_`,)
+        The list of lower bound values on the log-likelihood from each

+
+The estimators provided in this module are meta-estimators: they require a base
+estimator to be provided in their constructor. For example, it is possible to
+use these estimators to turn a binary classifier or a regressor into a
+multiclass classifier. It is also possible to use these estimators with
+multiclass estimators in the hope that their accuracy or runtime performance
+improves.
+
+All classifiers in scikit-learn implement multiclass classification; you
+only need to use this module if you want to experiment with custom multiclass
+strategies.
+
+The one-vs-the-rest meta-classifier also implements a `predict_proba` method,
+so long as such a method is implemented by the base classifier. This method
+returns probabilities of class membership in both the single label and
+multilabel case.  Note that in the multilabel case, probabilities are the
+marginal probability that a given sample falls in the given class. As such, in
+the multilabel case the sum of these probabilities over all possible labels
+for a given sample *will not* sum to unity, as they do in the single label
+case.

+
+    Also known as one-vs-all, this strategy consists in fitting one classifier

+    classes. In addition to its computational efficiency (only `n_classes`

+

+    `.fit`. In other words, the target labels should be formatted as a 2D
+    binary (0/1) matrix, where [i, j] == 1 indicates the presence of label j

+    Parameters
+    ----------
+    estimator : estimator object
+        A regressor or a classifier that implements :term:`fit`.
+        When a classifier is passed, :term:`decision_function` will be used
+        in priority and it will fallback to :term:`predict_proba` if it is not
+        available.
+        When a regressor is passed, :term:`predict` is used.
+
+    n_jobs : int, default=None
+        The number of jobs to use for the computation: the `n_classes`
+        one-vs-rest problems are computed in parallel.
+
+        ``None`` means 1 unless in a :obj:`joblib.parallel_backend` context.

+        for more details.
+
+        .. versionchanged:: 0.20
+           `n_jobs` default changed from 1 to None
+
+    verbose : int, default=0
+        The verbosity level, if non zero, progress messages are printed.
+        Below 50, the output is sent to stderr. Otherwise, the output is sent
+        to stdout. The frequency of the messages increases with the verbosity

+        Object used to transform multiclass labels to binary labels and
+        vice-versa.
+
+    multilabel_ : boolean
+        Whether a OneVsRestClassifier is a multilabel classifier.
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`. Only defined if the
+        underlying estimator exposes such an attribute when fit.
+
+        .. versionadded:: 0.24
+
+    feature_names_in_ : ndarray of shape (`n_features_in_`,)

+        The number of jobs to use for the computation: the multiclass problems
+        are computed in parallel.
+
+        ``None`` means 1 unless in a :obj:`joblib.parallel_backend` context.

+    Parameters
+    ----------
+    estimator : estimator
+        The base estimator from which the classifier chain is built.
+
+    order : array-like of shape (n_outputs,) or 'random', default=None
+        If `None`, the order will be determined by the order of columns in
+        the label matrix Y.::
+
+            order = [0, 1, 2, ..., Y.shape[1] - 1]
+
+        The order of the chain can be explicitly set by providing a list of
+        integers. For example, for a chain of length 5.::
+
+            order = [1, 3, 2, 4, 0]
+
+        means that the first model in the chain will make predictions for
+        column 1 in the Y matrix, the second model will make predictions
+        for column 3, etc.
+
+        If order is `random` a random ordering will be used.
+
+    cv : int, cross-validation generator or an iterable, default=None
+        Determines whether to use cross validated predictions or true
+        labels for the results of previous estimators in the chain.
+        Possible inputs for cv are:
+
+        - None, to use true labels when fitting,
+        - integer, to specify the number of folds in a (Stratified)KFold,
+        - :term:`CV splitter`,
+        - An iterable yielding (train, test) splits as arrays of indices.
+
+    chain_method : {'predict', 'predict_proba', 'predict_log_proba', \
+            'decision_function'} or list of such str's, default='predict'
+
+        Prediction method to be used by estimators in the chain for
+        the 'prediction' features of previous estimators in the chain.
+
+        - if `str`, name of the method;
+        - if a list of `str`, provides the method names in order of
+          preference. The method used corresponds to the first method in
+          the list that is implemented by `base_estimator`.
+
+        .. versionadded:: 1.5
+
+    random_state : int, RandomState instance or None, optional (default=None)
+        If ``order='random'``, determines random number generation for the
+        chain order.
+        In addition, it controls the random seed given at each `base_estimator`
+        at each chaining iteration. Thus, it is only used when `base_estimator`
+        exposes a `random_state`.
+        Pass an int for reproducible output across multiple function calls.
+        See :term:`Glossary `.
+
+    verbose : bool, default=False
+        If True, chain progress is output as each model is completed.
+
+        .. versionadded:: 1.2
+
+    base_estimator : estimator, default="deprecated"
+        Use `estimator` instead.

+            `base_estimator` is deprecated and will be removed in 1.9.
+            Use `estimator` instead.
+
+    Attributes
+    ----------
+    classes_ : list
+        A list of arrays of length ``len(estimators_)`` containing the
+        class labels for each estimator in the chain.
+
+    estimators_ : list
+        A list of clones of base_estimator.
+
+    order_ : list

+
+    chain_method_ : str
+        Prediction method used by estimators in the chain for the prediction
+        features.
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`. Only defined if the
+        underlying `base_estimator` exposes such an attribute when fit.
+
+        .. versionadded:: 0.24
+
+    feature_names_in_ : ndarray of shape (`n_features_in_`,)

+
+    Parameters
+    ----------
+    estimator : estimator
+        The base estimator from which the regressor chain is built.
+
+    order : array-like of shape (n_outputs,) or 'random', default=None
+        If `None`, the order will be determined by the order of columns in
+        the label matrix Y.::
+
+            order = [0, 1, 2, ..., Y.shape[1] - 1]
+
+        The order of the chain can be explicitly set by providing a list of

+
+            order = [1, 3, 2, 4, 0]
+
+        means that the first model in the chain will make predictions for

+        for column 3, etc.
+
+        If order is 'random' a random ordering will be used.
+
+    cv : int, cross-validation generator or an iterable, default=None
+        Determines whether to use cross validated predictions or true
+        labels for the results of previous estimators in the chain.
+        Possible inputs for cv are:
+
+        - None, to use true labels when fitting,
+        - integer, to specify the number of folds in a (Stratified)KFold,
+        - :term:`CV splitter`,
+        - An iterable yielding (train, test) splits as arrays of indices.
+
+    random_state : int, RandomState instance or None, optional (default=None)
+        If ``order='random'``, determines random number generation for the
+        chain order.
+        In addition, it controls the random seed given at each `base_estimator`
+        at each chaining iteration. Thus, it is only used when `base_estimator`
+        exposes a `random_state`.
+        Pass an int for reproducible output across multiple function calls.
+        See :term:`Glossary `.
+
+    verbose : bool, default=False
+        If True, chain progress is output as each model is completed.

+    """
+    A sequence of data transformers with an optional final predictor.
+
+    `Pipeline` allows you to sequentially apply a list of transformers to
+    preprocess the data and, if desired, conclude the sequence with a final
+    :term:`predictor` for predictive modeling.
+
+    Intermediate steps of the pipeline must be transformers, that is, they
+    must implement `fit` and `transform` methods.
+    The final :term:`estimator` only needs to implement `fit`.
+    The transformers in the pipeline can be cached using ``memory`` argument.
+
+    The purpose of the pipeline is to assemble several steps that can be
+    cross-validated together while setting different parameters. For this, it
+    enables setting parameters of the various steps using their names and the
+    parameter name separated by a `'__'`, as in the example below. A step's
+    estimator may be replaced entirely by setting the parameter with its name
+    to another estimator, or a transformer removed by setting it to
+    `'passthrough'` or `None`.
+
+    For an example use case of `Pipeline` combined with
+    :class:`~sklearn.model_selection.GridSearchCV`, refer to
+    :ref:`sphx_glr_auto_examples_compose_plot_compare_reduction.py`. The
+    example :ref:`sphx_glr_auto_examples_compose_plot_digits_pipe.py` shows how
+    to grid search on a pipeline using `'__'` as a separator in the parameter names.
+
+    Read more in the :ref:`User Guide `.
+
+    .. versionadded:: 0.5
+
+    Parameters
+    ----------
+    steps : list of tuples
+        List of (name of step, estimator) tuples that are to be chained in
+        sequential order. To be compatible with the scikit-learn API, all steps
+        must define `fit`. All non-last steps must also define `transform`. See
+        :ref:`Combining Estimators ` for more details.
+
+    transform_input : list of str, default=None
+        The names of the :term:`metadata` parameters that should be transformed by the
+        pipeline before passing it to the step consuming it.
+
+        This enables transforming some input arguments to ``fit`` (other than ``X``)
+        to be transformed by the steps of the pipeline up to the step which requires
+        them. Requirement is defined via :ref:`metadata routing `.
+        For instance, this can be used to pass a validation set through the pipeline.
+
+        You can only set this if metadata routing is enabled, which you
+        can enable using ``sklearn.set_config(enable_metadata_routing=True)``.
+
+        .. versionadded:: 1.6
+
+    memory : str or object with the joblib.Memory interface, default=None
+        Used to cache the fitted transformers of the pipeline. The last step
+        will never be cached, even if it is a transformer. By default, no
+        caching is performed. If a string is given, it is the path to the
+        caching directory. Enabling caching triggers a clone of the transformers
+        before fitting. Therefore, the transformer instance given to the
+        pipeline cannot be inspected directly. Use the attribute ``named_steps``
+        or ``steps`` to inspect estimators within the pipeline. Caching the
+        transformers is advantageous when fitting is time consuming. See
+        :ref:`sphx_glr_auto_examples_neighbors_plot_caching_nearest_neighbors.py`
+        for an example on how to enable caching.
+
+    verbose : bool, default=False
+        If True, the time elapsed while fitting each step will be printed as it
+        is completed.
+
+    Attributes
+    ----------
+    named_steps : :class:`~sklearn.utils.Bunch`
+        Dictionary-like object, with the following attributes.
+        Read-only attribute to access any step parameter by user given name.
+        Keys are step names and values are steps parameters.
+
+    classes_ : ndarray of shape (n_classes,)
+        The classes labels. Only exist if the last step of the pipeline is a
+        classifier.
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`. Only defined if the
+        underlying first estimator in `steps` exposes such an attribute
+        when fit.

+
+    This estimator applies a list of transformer objects in parallel to the

+    several feature extraction mechanisms into a single transformer.
+
+    Parameters of the transformers may be set using its name and the parameter
+    name separated by a '__'. A transformer may be replaced entirely by
+    setting the parameter with its name to another transformer, removed by
+    setting to 'drop' or disabled by setting to 'passthrough' (features are
+    passed without transformation).

+
+    Parameters
+    ----------
+    transformer_list : list of (str, transformer) tuples
+        List of transformer objects to be applied to the data. The first
+        half of each tuple is the name of the transformer. The transformer can
+        be 'drop' for it to be ignored or can be 'passthrough' for features to
+        be passed unchanged.
+
+        .. versionadded:: 1.1
+           Added the option `"passthrough"`.
+
+        .. versionchanged:: 0.22
+           Deprecated `None` as a transformer in favor of 'drop'.
+
+    n_jobs : int, default=None
+        Number of jobs to run in parallel.
+        ``None`` means 1 unless in a :obj:`joblib.parallel_backend` context.
+        ``-1`` means using all processors. See :term:`Glossary `
+        for more details.
+
+        .. versionchanged:: v0.20
+           `n_jobs` default changed from 1 to None
+
+    transformer_weights : dict, default=None
+        Multiplicative weights for features per transformer.
+        Keys are transformer names, values the weights.
+        Raises ValueError if key not present in ``transformer_list``.
+
+    verbose : bool, default=False
+        If True, the time elapsed while fitting each transformer will be
+        printed as it is completed.
+
+    verbose_feature_names_out : bool, default=True
+        If True, :meth:`get_feature_names_out` will prefix all feature names

+    Attributes
+    ----------

+        Dictionary-like object, with the following attributes.
+        Read-only attribute to access any transformer parameter by user
+        given name. Keys are transformer names and values are
+        transformer parameters.
+
+        .. versionadded:: 1.2
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`. Only defined if the
+        underlying first transformer in `transformer_list` exposes such an
+        attribute when fit.
+
+        .. versionadded:: 0.24
+
+    feature_names_in_ : ndarray of shape (`n_features_in_`,)
+        Names of features seen during :term:`fit`. Defined only when
+        `X` has feature names that are all strings.

+"""Random projection transformers.
+
+Random projections are a simple and computationally efficient way to
+reduce the dimensionality of the data by trading a controlled amount
+of accuracy (as additional variance) for faster processing times and
+smaller model sizes.
+
+The dimensions and distribution of random projections matrices are
+controlled so as to preserve the pairwise distances between any two
+samples of the dataset.
+
+The main theoretical result behind the efficiency of random projection is the
+`Johnson-Lindenstrauss lemma (quoting Wikipedia)
+`_:
+
+  In mathematics, the Johnson-Lindenstrauss lemma is a result
+  concerning low-distortion embeddings of points from high-dimensional
+  into low-dimensional Euclidean space. The lemma states that a small set
+  of points in a high-dimensional space can be embedded into a space of
+  much lower dimension in such a way that distances between the points are
+  nearly preserved. The map used for the embedding is at least Lipschitz,
+  and can even be taken to be an orthogonal projection.

+
+    The distortion introduced by a random projection `p` only changes the

+
+    Parameters
+    ----------
+    X : {array-like, sparse matrix} of shape (n_samples, n_features)
+        Training vector, where `n_samples` is the number of samples and
+        `n_features` is the number of features.
+
+    y : array-like of shape (n_samples,)
+        Target vector relative to X
+
+    C : float
+        Inverse of cross-validation parameter. The lower the C, the higher
+        the penalization.
+
+    fit_intercept : bool
+        Whether or not to fit an intercept. If set to True, the feature vector
+        is extended to include an intercept term: ``[x_1, ..., x_n, 1]``, where
+        1 corresponds to the intercept. If set to False, no intercept will be
+        used in calculations (i.e. data is expected to be already centered).
+
+    intercept_scaling : float
+        Liblinear internally penalizes the intercept, treating it like any
+        other term in the feature vector. To reduce the impact of the
+        regularization on the intercept, the `intercept_scaling` parameter can
+        be set to a value greater than 1; the higher the value of
+        `intercept_scaling`, the lower the impact of regularization on it.
+        Then, the weights become `[w_x_1, ..., w_x_n,
+        w_intercept*intercept_scaling]`, where `w_x_1, ..., w_x_n` represent
+        the feature weights and the intercept weight is scaled by
+        `intercept_scaling`. This scaling allows the intercept term to have a
+        different regularization behavior compared to the other features.
+
+    class_weight : dict or 'balanced', default=None
+        Weights associated with classes in the form ``{class_label: weight}``.
+        If not given, all classes are supposed to have weight one. For
+        multi-output problems, a list of dicts can be provided in the same
+        order as the columns of y.
+
+        The "balanced" mode uses the values of y to automatically adjust
+        weights inversely proportional to class frequencies in the input data
+        as ``n_samples / (n_classes * np.bincount(y))``
+
+    penalty : {'l1', 'l2'}
+        The norm of the penalty used in regularization.
+
+    dual : bool
+        Dual or primal formulation,
+
+    verbose : int
+        Set verbose to any positive number for verbosity.
+
+    max_iter : int
+        Number of iterations.
+
+    tol : float
+        Stopping condition.
+
+    random_state : int, RandomState instance or None, default=None
+        Controls the pseudo random number generation for shuffling the data.
+        Pass an int for reproducible output across multiple function calls.
+        See :term:`Glossary `.
+
+    multi_class : {'ovr', 'crammer_singer'}, default='ovr'
+        `ovr` trains n_classes one-vs-rest classifiers, while `crammer_singer`
+        optimizes a joint objective over all classes.
+        While `crammer_singer` is interesting from an theoretical perspective
+        as it is consistent it is seldom used in practice and rarely leads to
+        better accuracy and is more expensive to compute.
+        If `crammer_singer` is chosen, the options loss, penalty and dual will
+        be ignored.
+
+    loss : {'logistic_regression', 'hinge', 'squared_hinge', \
+            'epsilon_insensitive', 'squared_epsilon_insensitive}, \
+            default='logistic_regression'
+        The loss function used to fit the model.
+
+    epsilon : float, default=0.1
+        Epsilon parameter in the epsilon-insensitive loss function. Note
+        that the value of this parameter depends on the scale of the target
+        variable y. If unsure, set epsilon=0.
+
+    sample_weight : array-like of shape (n_samples,), default=None
+        Weights assigned to each sample.
+
+    Returns
+    -------

+    :class:`~sklearn.svm.SVC` lie in the loss function used by default, and in
+    the handling of intercept regularization between those two implementations.
+
+    This class supports both dense and sparse input and the multiclass support
+    is handled according to a one-vs-the-rest scheme.

+
+    Parameters
+    ----------
+    penalty : {'l1', 'l2'}, default='l2'
+        Specifies the norm used in the penalization. The 'l2'
+        penalty is the standard used in SVC. The 'l1' leads to ``coef_``
+        vectors that are sparse.
+
+    loss : {'hinge', 'squared_hinge'}, default='squared_hinge'
+        Specifies the loss function. 'hinge' is the standard SVM loss
+        (used e.g. by the SVC class) while 'squared_hinge' is the
+        square of the hinge loss. The combination of ``penalty='l1'``
+        and ``loss='hinge'`` is not supported.
+
+    dual : "auto" or bool, default="auto"
+        Select the algorithm to either solve the dual or primal
+        optimization problem. Prefer dual=False when n_samples > n_features.
+        `dual="auto"` will choose the value of the parameter automatically,
+        based on the values of `n_samples`, `n_features`, `loss`, `multi_class`
+        and `penalty`. If `n_samples` < `n_features` and optimizer supports
+        chosen `loss`, `multi_class` and `penalty`, then dual will be set to True,
+        otherwise it will be set to False.
+
+        .. versionchanged:: 1.3
+           The `"auto"` option is added in version 1.3 and will be the default
+           in version 1.5.
+
+    tol : float, default=1e-4
+        Tolerance for stopping criteria.
+
+    C : float, default=1.0
+        Regularization parameter. The strength of the regularization is
+        inversely proportional to C. Must be strictly positive.
+        For an intuitive visualization of the effects of scaling
+        the regularization parameter C, see
+        :ref:`sphx_glr_auto_examples_svm_plot_svm_scale_c.py`.
+
+    multi_class : {'ovr', 'crammer_singer'}, default='ovr'
+        Determines the multi-class strategy if `y` contains more than
+        two classes.
+        ``"ovr"`` trains n_classes one-vs-rest classifiers, while
+        ``"crammer_singer"`` optimizes a joint objective over all classes.
+        While `crammer_singer` is interesting from a theoretical perspective
+        as it is consistent, it is seldom used in practice as it rarely leads
+        to better accuracy and is more expensive to compute.
+        If ``"crammer_singer"`` is chosen, the options loss, penalty and dual
+        will be ignored.
+
+    fit_intercept : bool, default=True
+        Whether or not to fit an intercept. If set to True, the feature vector
+        is extended to include an intercept term: `[x_1, ..., x_n, 1]`, where
+        1 corresponds to the intercept. If set to False, no intercept will be
+        used in calculations (i.e. data is expected to be already centered).
+
+    intercept_scaling : float, default=1.0
+        When `fit_intercept` is True, the instance vector x becomes ``[x_1,
+        ..., x_n, intercept_scaling]``, i.e. a "synthetic" feature with a
+        constant value equal to `intercept_scaling` is appended to the instance
+        vector. The intercept becomes intercept_scaling * synthetic feature
+        weight. Note that liblinear internally penalizes the intercept,
+        treating it like any other term in the feature vector. To reduce the
+        impact of the regularization on the intercept, the `intercept_scaling`
+        parameter can be set to a value greater than 1; the higher the value of
+        `intercept_scaling`, the lower the impact of regularization on it.
+        Then, the weights become `[w_x_1, ..., w_x_n,
+        w_intercept*intercept_scaling]`, where `w_x_1, ..., w_x_n` represent
+        the feature weights and the intercept weight is scaled by
+        `intercept_scaling`. This scaling allows the intercept term to have a
+        different regularization behavior compared to the other features.
+
+    class_weight : dict or 'balanced', default=None
+        Set the parameter C of class i to ``class_weight[i]*C`` for
+        SVC. If not given, all classes are supposed to have
+        weight one.
+        The "balanced" mode uses the values of y to automatically adjust
+        weights inversely proportional to class frequencies in the input data
+        as ``n_samples / (n_classes * np.bincount(y))``.
+
+    verbose : int, default=0
+        Enable verbose output. Note that this setting takes advantage of a
+        per-process runtime setting in liblinear that, if enabled, may not work
+        properly in a multithreaded context.
+
+    random_state : int, RandomState instance or None, default=None
+        Controls the pseudo random number generation for shuffling the data for
+        the dual coordinate descent (if ``dual=True``). When ``dual=False`` the
+        underlying implementation of :class:`LinearSVC` is not random and
+        ``random_state`` has no effect on the results.
+        Pass an int for reproducible output across multiple function calls.
+        See :term:`Glossary `.
+
+    max_iter : int, default=1000
+        The maximum number of iterations to be run.
+
+    Attributes
+    ----------
+    coef_ : ndarray of shape (1, n_features) if n_classes == 2 \
+            else (n_classes, n_features)
+        Weights assigned to the features (coefficients in the primal
+        problem).
+
+        ``coef_`` is a readonly property derived from ``raw_coef_`` that
+        follows the internal memory layout of liblinear.
+
+    intercept_ : ndarray of shape (1,) if n_classes == 2 else (n_classes,)
+        Constants in decision function.
+
+    classes_ : ndarray of shape (n_classes,)
+        The unique classes labels.
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`.
+
+        .. versionadded:: 0.24
+
+    feature_names_in_ : ndarray of shape (`n_features_in_`,)
+        Names of features seen during :term:`fit`. Defined only when `X`
+        has feature names that are all strings.
+
+        .. versionadded:: 1.0
+
+    n_iter_ : int
+        Maximum number of iterations run across all classes.
+
+    See Also
+    --------
+    SVC : Implementation of Support Vector Machine classifier using libsvm:
+        the kernel can be non-linear but its SMO algorithm does not
+        scale to large number of samples as LinearSVC does.
+
+        Furthermore SVC multi-class mode is implemented using one
+        vs one scheme while LinearSVC uses one vs the rest. It is
+        possible to implement one vs the rest with SVC by using the
+        :class:`~sklearn.multiclass.OneVsRestClassifier` wrapper.
+
+        Finally SVC can fit dense data without memory copy if the input
+        is C-contiguous. Sparse data will still incur memory copy though.
+
+    sklearn.linear_model.SGDClassifier : SGDClassifier can optimize the same
+        cost function as LinearSVC
+        by adjusting the penalty and loss parameters. In addition it requires
+        less memory, allows incremental (online) learning, and implements
+        various loss functions and regularization regimes.
+
+    Notes
+    -----
+    The underlying C implementation uses a random number generator to
+    select features when fitting the model. It is thus not uncommon
+    to have slightly different results for the same input data. If
+    that happens, try with a smaller ``tol`` parameter.
+
+    The underlying implementation, liblinear, uses a sparse internal
+    representation for the data that will incur a memory copy.
+
+    Predict output may not match that of standalone liblinear in certain
+    cases. See :ref:`differences from liblinear `
+    in the narrative documentation.

+
+    Parameters
+    ----------
+    epsilon : float, default=0.0
+        Epsilon parameter in the epsilon-insensitive loss function. Note
+        that the value of this parameter depends on the scale of the target
+        variable y. If unsure, set ``epsilon=0``.
+
+    tol : float, default=1e-4
+        Tolerance for stopping criteria.
+
+    C : float, default=1.0
+        Regularization parameter. The strength of the regularization is
+        inversely proportional to C. Must be strictly positive.
+
+    loss : {'epsilon_insensitive', 'squared_epsilon_insensitive'}, \
+            default='epsilon_insensitive'
+        Specifies the loss function. The epsilon-insensitive loss
+        (standard SVR) is the L1 loss, while the squared epsilon-insensitive
+        loss ('squared_epsilon_insensitive') is the L2 loss.
+
+    fit_intercept : bool, default=True
+        Whether or not to fit an intercept. If set to True, the feature vector
+        is extended to include an intercept term: `[x_1, ..., x_n, 1]`, where
+        1 corresponds to the intercept. If set to False, no intercept will be
+        used in calculations (i.e. data is expected to be already centered).
+
+    intercept_scaling : float, default=1.0
+        When `fit_intercept` is True, the instance vector x becomes `[x_1, ...,
+        x_n, intercept_scaling]`, i.e. a "synthetic" feature with a constant
+        value equal to `intercept_scaling` is appended to the instance vector.
+        The intercept becomes intercept_scaling * synthetic feature weight.
+        Note that liblinear internally penalizes the intercept, treating it
+        like any other term in the feature vector. To reduce the impact of the
+        regularization on the intercept, the `intercept_scaling` parameter can
+        be set to a value greater than 1; the higher the value of
+        `intercept_scaling`, the lower the impact of regularization on it.
+        Then, the weights become `[w_x_1, ..., w_x_n,
+        w_intercept*intercept_scaling]`, where `w_x_1, ..., w_x_n` represent
+        the feature weights and the intercept weight is scaled by
+        `intercept_scaling`. This scaling allows the intercept term to have a
+        different regularization behavior compared to the other features.
+
+    dual : "auto" or bool, default="auto"
+        Select the algorithm to either solve the dual or primal
+        optimization problem. Prefer dual=False when n_samples > n_features.
+        `dual="auto"` will choose the value of the parameter automatically,
+        based on the values of `n_samples`, `n_features` and `loss`. If
+        `n_samples` < `n_features` and optimizer supports chosen `loss`,
+        then dual will be set to True, otherwise it will be set to False.

+        .. versionchanged:: 1.3
+           The `"auto"` option is added in version 1.3 and will be the default

+        Enable verbose output. Note that this setting takes advantage of a
+        per-process runtime setting in liblinear that, if enabled, may not work

+

+    ----------
+    C : float, default=1.0
+        Regularization parameter. The strength of the regularization is
+        inversely proportional to C. Must be strictly positive. The penalty
+        is a squared l2 penalty. For an intuitive visualization of the effects

+
+    kernel : {'linear', 'poly', 'rbf', 'sigmoid', 'precomputed'} or callable,  \
+        default='rbf'
+        Specifies the kernel type to be used in the algorithm. If
+        none is given, 'rbf' will be used. If a callable is given it is used to
+        pre-compute the kernel matrix from data matrices; that matrix should be

+        visualization of different kernel types see
+        :ref:`sphx_glr_auto_examples_svm_plot_svm_kernels.py`.
+
+    degree : int, default=3
+        Degree of the polynomial kernel function ('poly').
+        Must be non-negative. Ignored by all other kernels.
+
+    gamma : {'scale', 'auto'} or float, default='scale'

+           The default value of ``gamma`` changed from 'auto' to 'scale'.
+
+    coef0 : float, default=0.0
+        Independent term in kernel function.
+        It is only significant in 'poly' and 'sigmoid'.
+
+    shrinking : bool, default=True
+        Whether to use the shrinking heuristic.
+        See the :ref:`User Guide `.
+
+    probability : bool, default=False
+        Whether to enable probability estimates. This must be enabled prior
+        to calling `fit`, will slow down that method as it internally uses
+        5-fold cross-validation, and `predict_proba` may be inconsistent with
+        `predict`. Read more in the :ref:`User Guide `.
+
+    tol : float, default=1e-3
+        Tolerance for stopping criterion.
+
+    cache_size : float, default=200
+        Specify the size of the kernel cache (in MB).
+
+    class_weight : dict or 'balanced', default=None
+        Set the parameter C of class i to class_weight[i]*C for
+        SVC. If not given, all classes are supposed to have
+        weight one.
+        The "balanced" mode uses the values of y to automatically adjust

+        as ``n_samples / (n_classes * np.bincount(y))``.
+
+    verbose : bool, default=False
+        Enable verbose output. Note that this setting takes advantage of a

+        properly in a multithreaded context.
+
+    max_iter : int, default=-1
+        Hard limit on iterations within solver, or -1 for no limit.
+
+    decision_function_shape : {'ovo', 'ovr'}, default='ovr'
+        Whether to return a one-vs-rest ('ovr') decision function of shape
+        (n_samples, n_classes) as all other classifiers, or the original
+        one-vs-one ('ovo') decision function of libsvm which has shape

+        :term:`decision_function`; otherwise the first class among the tied

+
+        .. versionadded:: 0.22
+

+        - if float, must be non-negative.
+
+        .. versionchanged:: 0.22
+           The default value of ``gamma`` changed from 'auto' to 'scale'.
+
+    coef0 : float, default=0.0
+        Independent term in kernel function.
+        It is only significant in 'poly' and 'sigmoid'.
+
+    tol : float, default=1e-3
+        Tolerance for stopping criterion.
+
+    nu : float, default=0.5
+        An upper bound on the fraction of training
+        errors and a lower bound of the fraction of support
+        vectors. Should be in the interval (0, 1]. By default 0.5
+        will be taken.
+
+    shrinking : bool, default=True
+        Whether to use the shrinking heuristic.
+        See the :ref:`User Guide `.
+
+    cache_size : float, default=200
+        Specify the size of the kernel cache (in MB).
+
+    verbose : bool, default=False
+        Enable verbose output. Note that this setting takes advantage of a
+        per-process runtime setting in libsvm that, if enabled, may not work
+        properly in a multithreaded context.
+
+    max_iter : int, default=-1
+        Hard limit on iterations within solver, or -1 for no limit.
+
+    Attributes
+    ----------
+    coef_ : ndarray of shape (1, n_features)
+        Weights assigned to the features (coefficients in the primal
+        problem). This is only available in the case of a linear kernel.
+
+        `coef_` is readonly property derived from `dual_coef_` and
+        `support_vectors_`.
+
+    dual_coef_ : ndarray of shape (1, n_SV)
+        Coefficients of the support vectors in the decision function.
+
+    fit_status_ : int
+        0 if correctly fitted, 1 otherwise (will raise warning)
+
+    intercept_ : ndarray of shape (1,)
+        Constant in the decision function.
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`.
+
+        .. versionadded:: 0.24
+
+    feature_names_in_ : ndarray of shape (`n_features_in_`,)
+        Names of features seen during :term:`fit`. Defined only when `X`
+        has feature names that are all strings.
+
+        .. versionadded:: 1.0
+
+    n_iter_ : int
+        Number of iterations run by the optimization routine to fit the model.
+
+        .. versionadded:: 1.1
+
+    n_support_ : ndarray of shape (n_classes,), dtype=int32
+        Number of support vectors for each class.
+
+    offset_ : float
+        Offset used to define the decision function from the raw scores.
+        We have the relation: decision_function = score_samples - `offset_`.
+        The offset is the opposite of `intercept_` and is provided for
+        consistency with other outlier detection algorithms.
+
+        .. versionadded:: 0.20
+
+    shape_fit_ : tuple of int of shape (n_dimensions_of_X,)
+        Array dimensions of training vector ``X``.
+
+    support_ : ndarray of shape (n_SV,)
+        Indices of support vectors.
+
+    support_vectors_ : ndarray of shape (n_SV, n_features)
+        Support vectors.

+Binding for libsvm_skl
+----------------------
+
+These are the bindings for libsvm_skl, which is a fork of libsvm[1]
+that adds to libsvm some capabilities, like index of support vectors
+and efficient representation of dense matrices.
+
+These are low-level routines, but can be used for flexibility or
+performance reasons. See sklearn.svm for a higher-level API.
+
+Low-level memory management is done in libsvm_helper.c. If we happen
+to run out of memory a MemoryError will be raised. In practice this is
+not very helpful since high chances are malloc fails inside svm.cpp,
+where no sort of memory checks are done.

+Changes to Libsvm
+
+This is here mainly as checklist for incorporation of new versions of libsvm.
+
+  * Add copyright to files svm.cpp and svm.h
+  * Add random_seed support and call to srand in fit function
+  * Improved random number generator (fix on windows, enhancement on other
+    platforms). See 
+  * invoke scipy blas api for svm kernel function to improve performance with speedup rate of 1.5X to 2X for dense data only. See 
+  * Expose the number of iterations run in optimization. See 
+The changes made with respect to upstream are detailed in the heading of svm.cpp

+
+    Read more in the :ref:`User Guide `.
+
+    Parameters
+    ----------
+    criterion : {"gini", "entropy", "log_loss"}, default="gini"
+        The function to measure the quality of a split. Supported criteria are
+        "gini" for the Gini impurity and "log_loss" and "entropy" both for the
+        Shannon information gain, see :ref:`tree_mathematical_formulation`.
+
+    splitter : {"best", "random"}, default="best"
+        The strategy used to choose the split at each node. Supported
+        strategies are "best" to choose the best split and "random" to choose
+        the best random split.
+
+    max_depth : int, default=None
+        The maximum depth of the tree. If None, then nodes are expanded until
+        all leaves are pure or until all leaves contain less than
+        min_samples_split samples.
+
+    min_samples_split : int or float, default=2
+        The minimum number of samples required to split an internal node:
+
+        - If int, then consider `min_samples_split` as the minimum number.
+        - If float, then `min_samples_split` is a fraction and
+          `ceil(min_samples_split * n_samples)` are the minimum
+          number of samples for each split.
+
+        .. versionchanged:: 0.18
+           Added float values for fractions.
+
+    min_samples_leaf : int or float, default=1
+        The minimum number of samples required to be at a leaf node.
+        A split point at any depth will only be considered if it leaves at
+        least ``min_samples_leaf`` training samples in each of the left and
+        right branches.  This may have the effect of smoothing the model,
+        especially in regression.
+
+        - If int, then consider `min_samples_leaf` as the minimum number.
+        - If float, then `min_samples_leaf` is a fraction and
+          `ceil(min_samples_leaf * n_samples)` are the minimum
+          number of samples for each node.
+
+        .. versionchanged:: 0.18
+           Added float values for fractions.
+
+    min_weight_fraction_leaf : float, default=0.0
+        The minimum weighted fraction of the sum total of weights (of all
+        the input samples) required to be at a leaf node. Samples have
+        equal weight when sample_weight is not provided.
+
+    max_features : int, float or {"sqrt", "log2"}, default=None
+        The number of features to consider when looking for the best split:
+
+        - If int, then consider `max_features` features at each split.
+        - If float, then `max_features` is a fraction and
+          `max(1, int(max_features * n_features_in_))` features are considered at
+          each split.
+        - If "sqrt", then `max_features=sqrt(n_features)`.
+        - If "log2", then `max_features=log2(n_features)`.
+        - If None, then `max_features=n_features`.
+
+        .. note::
+
+            The search for a split does not stop until at least one
+            valid partition of the node samples is found, even if it requires to
+            effectively inspect more than ``max_features`` features.
+
+    random_state : int, RandomState instance or None, default=None
+        Controls the randomness of the estimator. The features are always
+        randomly permuted at each split, even if ``splitter`` is set to
+        ``"best"``. When ``max_features < n_features``, the algorithm will
+        select ``max_features`` at random at each split before finding the best
+        split among them. But the best found split may vary across different
+        runs, even if ``max_features=n_features``. That is the case, if the
+        improvement of the criterion is identical for several splits and one
+        split has to be selected at random. To obtain a deterministic behaviour
+        during fitting, ``random_state`` has to be fixed to an integer.
+        See :term:`Glossary ` for details.
+
+    max_leaf_nodes : int, default=None
+        Grow a tree with ``max_leaf_nodes`` in best-first fashion.
+        Best nodes are defined as relative reduction in impurity.
+        If None then unlimited number of leaf nodes.
+
+    min_impurity_decrease : float, default=0.0
+        A node will be split if this split induces a decrease of the impurity
+        greater than or equal to this value.
+
+        The weighted impurity decrease equation is the following::
+
+            N_t / N * (impurity - N_t_R / N_t * right_impurity
+                                - N_t_L / N_t * left_impurity)
+
+        where ``N`` is the total number of samples, ``N_t`` is the number of
+        samples at the current node, ``N_t_L`` is the number of samples in the
+        left child, and ``N_t_R`` is the number of samples in the right child.
+
+        ``N``, ``N_t``, ``N_t_R`` and ``N_t_L`` all refer to the weighted sum,
+        if ``sample_weight`` is passed.
+
+        .. versionadded:: 0.19
+
+    class_weight : dict, list of dict or "balanced", default=None
+        Weights associated with classes in the form ``{class_label: weight}``.
+        If None, all classes are supposed to have weight one. For
+        multi-output problems, a list of dicts can be provided in the same
+        order as the columns of y.
+
+        Note that for multioutput (including multilabel) weights should be
+        defined for each class of every column in its own dict. For example,
+        for four-class multilabel classification weights should be
+        [{0: 1, 1: 1}, {0: 1, 1: 5}, {0: 1, 1: 1}, {0: 1, 1: 1}] instead of
+        [{1:1}, {2:5}, {3:1}, {4:1}].
+
+        The "balanced" mode uses the values of y to automatically adjust
+        weights inversely proportional to class frequencies in the input data
+        as ``n_samples / (n_classes * np.bincount(y))``
+
+        For multi-output, the weights of each column of y will be multiplied.
+
+        Note that these weights will be multiplied with sample_weight (passed
+        through the fit method) if sample_weight is specified.
+
+    ccp_alpha : non-negative float, default=0.0
+        Complexity parameter used for Minimal Cost-Complexity Pruning. The
+        subtree with the largest cost complexity that is smaller than
+        ``ccp_alpha`` will be chosen. By default, no pruning is performed. See
+        :ref:`minimal_cost_complexity_pruning` for details. See
+        :ref:`sphx_glr_auto_examples_tree_plot_cost_complexity_pruning.py`
+        for an example of such pruning.
+
+        .. versionadded:: 0.22
+
+    monotonic_cst : array-like of int of shape (n_features), default=None
+        Indicates the monotonicity constraint to enforce on each feature.
+          - 1: monotonic increase
+          - 0: no constraint
+          - -1: monotonic decrease
+
+        If monotonic_cst is None, no constraints are applied.
+
+        Monotonicity constraints are not supported for:
+          - multiclass classifications (i.e. when `n_classes > 2`),
+          - multioutput classifications (i.e. when `n_outputs_ > 1`),
+          - classifications trained on data with missing values.
+
+        The constraints hold over the probability of the positive class.

+        The impurity-based feature importances.
+        The higher, the more important the feature.
+        The importance of a feature is computed as the (normalized)
+        total reduction of the criterion brought by that feature.  It is also

+    --------
+    DecisionTreeRegressor : A decision tree regressor.
+
+    Notes
+    -----
+    The default values for the parameters controlling the size of the trees
+    (e.g. ``max_depth``, ``min_samples_leaf``, etc.) lead to fully grown and
+    unpruned trees which can potentially be very large on some data sets. To
+    reduce memory consumption, the complexity and size of the trees should be
+    controlled by setting those parameter values.
+
+    The :meth:`predict` method operates using the :func:`numpy.argmax`
+    function on the outputs of :meth:`predict_proba`. This means that in
+    case the highest predicted probabilities are tied, the classifier will
+    predict the tied class with the lowest index in :term:`classes_`.

+    ----------
+    criterion : {"squared_error", "friedman_mse", "absolute_error", \
+            "poisson"}, default="squared_error"
+        The function to measure the quality of a split. Supported criteria
+        are "squared_error" for the mean squared error, which is equal to
+        variance reduction as feature selection criterion and minimizes the L2
+        loss using the mean of each terminal node, "friedman_mse", which uses

+           Mean Absolute Error (MAE) criterion.
+
+        .. versionadded:: 0.24
+            Poisson deviance criterion.
+
+    splitter : {"best", "random"}, default="best"
+        The strategy used to choose the split at each node. Supported
+        strategies are "best" to choose the best split and "random" to choose
+        the best random split.
+
+    max_depth : int, default=None
+        The maximum depth of the tree. If None, then nodes are expanded until
+        all leaves are pure or until all leaves contain less than
+        min_samples_split samples.
+
+        For an example of how ``max_depth`` influences the model, see
+        :ref:`sphx_glr_auto_examples_tree_plot_tree_regression.py`.
+
+    min_samples_split : int or float, default=2
+        The minimum number of samples required to split an internal node:
+
+        - If int, then consider `min_samples_split` as the minimum number.
+        - If float, then `min_samples_split` is a fraction and
+          `ceil(min_samples_split * n_samples)` are the minimum
+          number of samples for each split.
+
+        .. versionchanged:: 0.18
+           Added float values for fractions.
+
+    min_samples_leaf : int or float, default=1
+        The minimum number of samples required to be at a leaf node.
+        A split point at any depth will only be considered if it leaves at
+        least ``min_samples_leaf`` training samples in each of the left and
+        right branches.  This may have the effect of smoothing the model,
+        especially in regression.
+
+        - If int, then consider `min_samples_leaf` as the minimum number.
+        - If float, then `min_samples_leaf` is a fraction and
+          `ceil(min_samples_leaf * n_samples)` are the minimum
+          number of samples for each node.
+
+        .. versionchanged:: 0.18
+           Added float values for fractions.
+
+    min_weight_fraction_leaf : float, default=0.0
+        The minimum weighted fraction of the sum total of weights (of all
+        the input samples) required to be at a leaf node. Samples have
+        equal weight when sample_weight is not provided.
+
+    max_features : int, float or {"sqrt", "log2"}, default=None
+        The number of features to consider when looking for the best split:
+
+        - If int, then consider `max_features` features at each split.
+        - If float, then `max_features` is a fraction and
+          `max(1, int(max_features * n_features_in_))` features are considered at each
+          split.
+        - If "sqrt", then `max_features=sqrt(n_features)`.
+        - If "log2", then `max_features=log2(n_features)`.
+        - If None, then `max_features=n_features`.
+
+        Note: the search for a split does not stop until at least one
+        valid partition of the node samples is found, even if it requires to
+        effectively inspect more than ``max_features`` features.
+
+    random_state : int, RandomState instance or None, default=None
+        Controls the randomness of the estimator. The features are always
+        randomly permuted at each split, even if ``splitter`` is set to
+        ``"best"``. When ``max_features < n_features``, the algorithm will
+        select ``max_features`` at random at each split before finding the best
+        split among them. But the best found split may vary across different
+        runs, even if ``max_features=n_features``. That is the case, if the
+        improvement of the criterion is identical for several splits and one
+        split has to be selected at random. To obtain a deterministic behaviour
+        during fitting, ``random_state`` has to be fixed to an integer.
+        See :term:`Glossary ` for details.
+
+    max_leaf_nodes : int, default=None
+        Grow a tree with ``max_leaf_nodes`` in best-first fashion.
+        Best nodes are defined as relative reduction in impurity.
+        If None then unlimited number of leaf nodes.
+
+    min_impurity_decrease : float, default=0.0
+        A node will be split if this split induces a decrease of the impurity
+        greater than or equal to this value.
+
+        The weighted impurity decrease equation is the following::
+
+            N_t / N * (impurity - N_t_R / N_t * right_impurity
+                                - N_t_L / N_t * left_impurity)
+
+        where ``N`` is the total number of samples, ``N_t`` is the number of
+        samples at the current node, ``N_t_L`` is the number of samples in the
+        left child, and ``N_t_R`` is the number of samples in the right child.
+
+        ``N``, ``N_t``, ``N_t_R`` and ``N_t_L`` all refer to the weighted sum,
+        if ``sample_weight`` is passed.
+
+        .. versionadded:: 0.19
+
+    ccp_alpha : non-negative float, default=0.0
+        Complexity parameter used for Minimal Cost-Complexity Pruning. The
+        subtree with the largest cost complexity that is smaller than
+        ``ccp_alpha`` will be chosen. By default, no pruning is performed. See
+        :ref:`minimal_cost_complexity_pruning` for details. See
+        :ref:`sphx_glr_auto_examples_tree_plot_cost_complexity_pruning.py`
+        for an example of such pruning.
+
+        .. versionadded:: 0.22
+
+    monotonic_cst : array-like of int of shape (n_features), default=None
+        Indicates the monotonicity constraint to enforce on each feature.
+          - 1: monotonic increase
+          - 0: no constraint
+          - -1: monotonic decrease
+
+        If monotonic_cst is None, no constraints are applied.
+
+        Monotonicity constraints are not supported for:
+          - multioutput regressions (i.e. when `n_outputs_ > 1`),
+          - regressions trained on data with missing values.

+
+    Attributes
+    ----------
+    feature_importances_ : ndarray of shape (n_features,)
+        The feature importances.
+        The higher, the more important the feature.
+        The importance of a feature is computed as the
+        (normalized) total reduction of the criterion brought
+        by that feature. It is also known as the Gini importance [4]_.
+
+        Warning: impurity-based feature importances can be misleading for
+        high cardinality features (many unique values). See
+        :func:`sklearn.inspection.permutation_importance` as an alternative.
+
+    max_features_ : int
+        The inferred value of max_features.
+
+    n_features_in_ : int
+        Number of features seen during :term:`fit`.
+
+        .. versionadded:: 0.24
+
+    feature_names_in_ : ndarray of shape (`n_features_in_`,)
+        Names of features seen during :term:`fit`. Defined only when `X`
+        has feature names that are all strings.
+
+        .. versionadded:: 1.0
+
+    n_outputs_ : int
+        The number of outputs when ``fit`` is performed.
+
+    tree_ : Tree instance
+        The underlying Tree object. Please refer to
+        ``help(sklearn.tree._tree.Tree)`` for attributes of Tree object and
+        :ref:`sphx_glr_auto_examples_tree_plot_unveil_tree_structure.py`

+
+    Notes
+    -----
+    The default values for the parameters controlling the size of the trees
+    (e.g. ``max_depth``, ``min_samples_leaf``, etc.) lead to fully grown and
+    unpruned trees which can potentially be very large on some data sets. To
+    reduce memory consumption, the complexity and size of the trees should be
+    controlled by setting those parameter values.

+        Grow a tree with ``max_leaf_nodes`` in best-first fashion.
+        Best nodes are defined as relative reduction in impurity.
+        If None then unlimited number of leaf nodes.
+
+    min_impurity_decrease : float, default=0.0
+        A node will be split if this split induces a decrease of the impurity
+        greater than or equal to this value.
+
+        The weighted impurity decrease equation is the following::
+
+            N_t / N * (impurity - N_t_R / N_t * right_impurity
+                                - N_t_L / N_t * left_impurity)
+
+        where ``N`` is the total number of samples, ``N_t`` is the number of
+        samples at the current node, ``N_t_L`` is the number of samples in the
+        left child, and ``N_t_R`` is the number of samples in the right child.
+
+        ``N``, ``N_t``, ``N_t_R`` and ``N_t_L`` all refer to the weighted sum,
+        if ``sample_weight`` is passed.
+
+        .. versionadded:: 0.19
+
+    class_weight : dict, list of dict or "balanced", default=None
+        Weights associated with classes in the form ``{class_label: weight}``.
+        If None, all classes are supposed to have weight one. For
+        multi-output problems, a list of dicts can be provided in the same
+        order as the columns of y.
+
+        Note that for multioutput (including multilabel) weights should be
+        defined for each class of every column in its own dict. For example,
+        for four-class multilabel classification weights should be
+        [{0: 1, 1: 1}, {0: 1, 1: 5}, {0: 1, 1: 1}, {0: 1, 1: 1}] instead of
+        [{1:1}, {2:5}, {3:1}, {4:1}].
+
+        The "balanced" mode uses the values of y to automatically adjust
+        weights inversely proportional to class frequencies in the input data
+        as ``n_samples / (n_classes * np.bincount(y))``
+
+        For multi-output, the weights of each column of y will be multiplied.
+
+        Note that these weights will be multiplied with sample_weight (passed
+        through the fit method) if sample_weight is specified.
+
+    ccp_alpha : non-negative float, default=0.0
+        Complexity parameter used for Minimal Cost-Complexity Pruning. The
+        subtree with the largest cost complexity that is smaller than
+        ``ccp_alpha`` will be chosen. By default, no pruning is performed. See
+        :ref:`minimal_cost_complexity_pruning` for details. See
+        :ref:`sphx_glr_auto_examples_tree_plot_cost_complexity_pruning.py`
+        for an example of such pruning.
+
+        .. versionadded:: 0.22
+
+    monotonic_cst : array-like of int of shape (n_features), default=None
+        Indicates the monotonicity constraint to enforce on each feature.
+          - 1: monotonic increase
+          - 0: no constraint
+          - -1: monotonic decrease
+
+        If monotonic_cst is None, no constraints are applied.
+
+        Monotonicity constraints are not supported for:
+          - multiclass classifications (i.e. when `n_classes > 2`),
+          - multioutput classifications (i.e. when `n_outputs_ > 1`),
+          - classifications trained on data with missing values.
+
+        The constraints hold over the probability of the positive class.

+
+    Parameters
+    ----------
+    criterion : {"squared_error", "friedman_mse", "absolute_error", "poisson"}, \
+            default="squared_error"
+        The function to measure the quality of a split. Supported criteria
+        are "squared_error" for the mean squared error, which is equal to
+        variance reduction as feature selection criterion and minimizes the L2
+        loss using the mean of each terminal node, "friedman_mse", which uses
+        mean squared error with Friedman's improvement score for potential
+        splits, "absolute_error" for the mean absolute error, which minimizes
+        the L1 loss using the median of each terminal node, and "poisson" which
+        uses reduction in Poisson deviance to find splits.
+
+        .. versionadded:: 0.18
+           Mean Absolute Error (MAE) criterion.
+
+        .. versionadded:: 0.24
+            Poisson deviance criterion.
+
+    splitter : {"random", "best"}, default="random"
+        The strategy used to choose the split at each node. Supported
+        strategies are "best" to choose the best split and "random" to choose
+        the best random split.
+
+    max_depth : int, default=None
+        The maximum depth of the tree. If None, then nodes are expanded until
+        all leaves are pure or until all leaves contain less than
+        min_samples_split samples.
+
+    min_samples_split : int or float, default=2
+        The minimum number of samples required to split an internal node:
+
+        - If int, then consider `min_samples_split` as the minimum number.
+        - If float, then `min_samples_split` is a fraction and
+          `ceil(min_samples_split * n_samples)` are the minimum
+          number of samples for each split.
+
+        .. versionchanged:: 0.18
+           Added float values for fractions.
+
+    min_samples_leaf : int or float, default=1
+        The minimum number of samples required to be at a leaf node.
+        A split point at any depth will only be considered if it leaves at
+        least ``min_samples_leaf`` training samples in each of the left and
+        right branches.  This may have the effect of smoothing the model,
+        especially in regression.
+
+        - If int, then consider `min_samples_leaf` as the minimum number.
+        - If float, then `min_samples_leaf` is a fraction and
+          `ceil(min_samples_leaf * n_samples)` are the minimum
+          number of samples for each node.
+
+        .. versionchanged:: 0.18
+           Added float values for fractions.
+
+    min_weight_fraction_leaf : float, default=0.0
+        The minimum weighted fraction of the sum total of weights (of all
+        the input samples) required to be at a leaf node. Samples have
+        equal weight when sample_weight is not provided.
+
+    max_features : int, float, {"sqrt", "log2"} or None, default=1.0
+        The number of features to consider when looking for the best split:
+
+        - If int, then consider `max_features` features at each split.
+        - If float, then `max_features` is a fraction and
+          `max(1, int(max_features * n_features_in_))` features are considered at each
+          split.
+        - If "sqrt", then `max_features=sqrt(n_features)`.
+        - If "log2", then `max_features=log2(n_features)`.
+        - If None, then `max_features=n_features`.
+
+        .. versionchanged:: 1.1
+            The default of `max_features` changed from `"auto"` to `1.0`.
+
+        Note: the search for a split does not stop until at least one
+        valid partition of the node samples is found, even if it requires to
+        effectively inspect more than ``max_features`` features.
+
+    random_state : int, RandomState instance or None, default=None
+        Used to pick randomly the `max_features` used at each split.
+        See :term:`Glossary ` for details.
+
+    min_impurity_decrease : float, default=0.0
+        A node will be split if this split induces a decrease of the impurity
+        greater than or equal to this value.
+
+        The weighted impurity decrease equation is the following::
+
+            N_t / N * (impurity - N_t_R / N_t * right_impurity
+                                - N_t_L / N_t * left_impurity)
+
+        where ``N`` is the total number of samples, ``N_t`` is the number of
+        samples at the current node, ``N_t_L`` is the number of samples in the
+        left child, and ``N_t_R`` is the number of samples in the right child.
+
+        ``N``, ``N_t``, ``N_t_R`` and ``N_t_L`` all refer to the weighted sum,
+        if ``sample_weight`` is passed.
+
+        .. versionadded:: 0.19
+
+    max_leaf_nodes : int, default=None
+        Grow a tree with ``max_leaf_nodes`` in best-first fashion.
+        Best nodes are defined as relative reduction in impurity.
+        If None then unlimited number of leaf nodes.
+
+    ccp_alpha : non-negative float, default=0.0
+        Complexity parameter used for Minimal Cost-Complexity Pruning. The
+        subtree with the largest cost complexity that is smaller than
+        ``ccp_alpha`` will be chosen. By default, no pruning is performed. See
+        :ref:`minimal_cost_complexity_pruning` for details. See

+
+    Parameters
+    ----------
+    decision_tree : decision tree regressor or classifier
+        The decision tree to be plotted.
+
+    max_depth : int, default=None
+        The maximum depth of the representation. If None, the tree is fully
+        generated.
+
+    feature_names : array-like of str, default=None
+        Names of each of the features.
+        If None, generic names will be used ("x[0]", "x[1]", ...).
+
+    class_names : array-like of str or True, default=None
+        Names of each of the target classes in ascending numerical order.
+        Only relevant for classification and not supported for multi-output.
+        If ``True``, shows a symbolic representation of the class name.
+
+    label : {'all', 'root', 'none'}, default='all'
+        Whether to show informative labels for impurity, etc.
+        Options include 'all' to show at every node, 'root' to show only at
+        the top root node, or 'none' to not show at any node.
+
+    filled : bool, default=False
+        When set to ``True``, paint nodes to indicate majority class for
+        classification, extremity of values for regression, or purity of node
+        for multi-output.
+
+    impurity : bool, default=True
+        When set to ``True``, show the impurity at each node.
+
+    node_ids : bool, default=False
+        When set to ``True``, show the ID number on each node.
+
+    proportion : bool, default=False
+        When set to ``True``, change the display of 'values' and/or 'samples'
+        to be proportions and percentages respectively.
+
+    rounded : bool, default=False
+        When set to ``True``, draw node boxes with rounded corners and use
+        Helvetica fonts instead of Times-Roman.
+
+    precision : int, default=3
+        Number of digits of precision for floating point in the values of
+        impurity, threshold and value attributes of each node.
+
+    ax : matplotlib axis, default=None
+        Axes to plot to. If None, use current axis. Any previous content
+        is cleared.
+
+    fontsize : int, default=None
+        Size of text font. If None, determined automatically to fit figure.
+
+    Returns
+    -------
+    annotations : list of artists
+        List containing the artists for the annotation boxes making up the
+        tree.
