如何使用pyarrow存储自定义拼图数据集元数据？

import pyarrow as pa
import pyarrow.parquet as pq

metadata = {
    'dataset_name': 'Custom Dataset',
    'author': 'Your Name',
    'description': 'Description of the dataset',
    'created_date': '2022-01-01',
    'version': '1.0'
}

metadata_table = pa.Table.from_pandas(pd.DataFrame(metadata, index=[0]))

metadata_file = 'metadata.parquet'

pq.write_table(metadata_table, metadata_file)
