Usage

• Load the dataset from Hugging Face Hub

from datasets import load_dataset

ds = load_dataset("lh9171338/YorkUrban")
# or load from `refs/convert/parquet` for acceleration
# from datasets import load_dataset, Features, Image, Sequence, Value
# features = Features({
#     "image": Image(),
#     "image_file": Value("string"),
#     "image_size": Sequence(Value("int32")),
#     "lines": Sequence(Sequence(Sequence(Value("float32")))),
# })
# ds = load_dataset("lh9171338/YorkUrban", features=features, revision="refs/convert/parquet")
print(ds)
# DatasetDict({
#     test: Dataset({
#         features: ['image', 'image_file', 'image_size', 'lines'],
#         num_rows: 102
#     })
# })
print(ds["test"][0].keys())
# dict_keys(['image', 'image_file', 'image_size', 'lines'])

• Load the dataset from local

from datasets import load_dataset

ds = load_dataset("imagefolder", data_dir=".")
print(ds)
# DatasetDict({
#     test: Dataset({
#         features: ['image', 'image_file', 'image_size', 'lines'],
#         num_rows: 102
#     })
# })
print(ds["test"][0].keys())
# dict_keys(['image', 'image_file', 'image_size', 'lines'])

• Load the dataset with jsonl files

import jsonlines

with jsonlines.open("test/metadata.jsonl") as reader:
    infos = list(reader)
print(infos[0].keys())
# dict_keys(['file_name', 'image_file', 'image_size', 'lines'])
