class BCOConfig(TrainingArguments):
r"""
Configuration class for the [`BCOTrainer`].
Using [`~transformers.HfArgumentParser`] we can turn this class into
[argparse](https://docs.python.org/3/library/argparse#module-argparse) arguments that can be specified on the
command line.
Parameters:
max_length (`Optional[int]`, *optional*, defaults to `None`):
Maximum length of the sequences (prompt + completion) in the batch. This argument is required if you want
to use the default data collator.
max_prompt_length (`Optional[int]`, *optional*, defaults to `None`):
Maximum length of the prompt. This argument is required if you want to use the default data collator.
max_completion_length (`Optional[int]`, *optional*, defaults to `None`):
Maximum length of the completion. This argument is required if you want to use the default data collator
and your model is an encoder-decoder.
beta (`float`, *optional*, defaults to `0.1`):
Parameter controlling the deviation from the reference model. Higher β means less deviation from the
reference model.
label_pad_token_id (`int`, *optional*, defaults to `-100`):
Label pad token id. This argument is required if you want to use the default data collator.
padding_value (`Optional[int]`, *optional*, defaults to `None`):
Padding value to use. If `None`, the padding value of the tokenizer is used.
truncation_mode (`str`, *optional*, defaults to `"keep_end"`):
Truncation mode to use when the prompt is too long. Possible values are `"keep_end"` or `"keep_start"`.
This argument is required if you want to use the default data collator.
generate_during_eval (`bool`, *optional*, defaults to `False`):
If `True`, generates and logs completions from both the model and the reference model to W&B during
evaluation.
is_encoder_decoder (`Optional[bool]`, *optional*, defaults to `None`):
When using the `model_init` argument (callable) to instantiate the model instead of the `model` argument,
you need to specify if the model returned by the callable is an encoder-decoder model.
precompute_ref_log_probs (`bool`, *optional*, defaults to `False`):
Whether to precompute reference model log probabilities for training and evaluation datasets. This is
useful when training without the reference model to reduce the total GPU memory needed.
model_init_kwargs (`Optional[Dict[str, Any]]`, *optional*, defaults to `None`):
Keyword arguments to pass to `AutoModelForCausalLM.from_pretrained` when instantiating the model from a
string.
ref_model_init_kwargs (`Optional[Dict[str, Any]]`, *optional*, defaults to `None`):
Keyword arguments to pass to `AutoModelForCausalLM.from_pretrained` when instantiating the reference model
from a string.
dataset_num_proc (`Optional[int]`, *optional*, defaults to `None`):
Number of processes to use for processing the dataset.
prompt_sample_size (`int`, *optional*, defaults to `1024`):
Number of prompts that are fed to density ratio classifier.
min_density_ratio (`float`, *optional*, defaults to `0.5`):
Minimum value of the density ratio. The estimated density ratio is clamped to this value.
max_density_ratio (`float`, *optional*, defaults to `10.0`):
Maximum value of the density ratio. The estimated density ratio is clamped to this value.
