Load from Hugging Face Hub datasets.

Initialize the HuggingFaceDatasetLoader.

Parameters:

  • path (str) – Path or name of the dataset.

  • page_content_column (str) – Page content column name. Default is “text”.

  • name (str | None) – Name of the dataset configuration.

  • data_dir (str | None) – Data directory of the dataset configuration.

  • data_files (str | Sequence[str] | Mapping[str, str | Sequence[str]] | None) – Path(s) to source data file(s).

  • cache_dir (str | None) – Directory to read/write data.

  • keep_in_memory (bool | None) – Whether to copy the dataset in-memory.

  • save_infos (bool) – Save the dataset information (checksums/size/splits/…). Default is False.

  • use_auth_token (bool | str | None) – Bearer token for remote files on the Dataset Hub.

  • num_proc (int | None) – Number of processes.
