2.14.0

Important: caching

• Datasets downloaded and cached using datasets>=2.14.0 may not be reloaded from cache using older version of datasets (and therefore re-downloaded).
• Datasets that were already cached are still supported.
• This affects datasets on Hugging Face without dataset scripts, e.g. made of pure parquet, csv, jsonl, etc. files.
• This is due to the default configuration name for those datasets have been fixed (from "username--dataset_name" to "default") in #5331.

Dataset Configuration

• Support for multiple configs via metadata yaml info by @polinaeterna in #5331

  • Configure your dataset using YAML at the top of your dataset card (docs here)
  • Choose which file goes into which split

    ---
    configs:
    - config_name: default
      data_files:
      - split: train
         path: data.csv
      - split: test
          path: holdout.csv
    ---

  • Define multiple dataset configurations

    ---
    configs:
    - config_name: main_data
      data_files: main_data.csv
    - config_name: additional_data
      data_files: additional_data.csv
    ---

Dataset Features

• Support for multiple configs via metadata yaml info by @polinaeterna in #5331

  • push_to_hub() additional dataset configurations

  ds.push_to_hub("username/dataset_name", config_name="additional_data")
  # reload later
  ds = load_dataset("username/dataset_name", "additional_data")
