Full Changelog: 2.16.0...2.16.1

2.16.0

Security features

• Add trust_remote_code argument by @lhoestq in #6429
  • Some Hugging Face datasets contain custom code which must be executed to correctly load the dataset. The code can be inspected in the repository content at https://hf.co/datasets/<repo_id>. A warning is shown to let the user know about the custom code, and they can avoid this message in future by passing the argument trust_remote_code=True.
  • Passing trust_remote_code=True will be mandatory to load these datasets from the next major release of datasets.
  • Using the environment variable HF_DATASETS_TRUST_REMOTE_CODE=0 you can already disable custom code by default without waiting for the next release of datasets
• Use parquet export if possible by @lhoestq in #6448
  • This allows loading most old datasets based on custom code by downloading the Parquet export provided by Hugging Face
  • You can see a dataset's Parquet export at https://hf.co/datasets/<repo_id>/tree/refs%2Fconvert%2Fparquet

Features

• Webdataset dataset builder by @lhoestq in #6391
• Implement get dataset default config name by @albertvillanova in #6511
• Lazy data files resolution and offline cache reload by @lhoestq in #6493
  • This speeds up the load_dataset step that lists the data files of big repositories (up to x100) but requires huggingface_hub 0.20 or newer
  • Fix load_dataset that used to reload data from cache even if the dataset was updated on Hugging Face
  • Reload a dataset from your cache even if you don't have internet connection
  • New cache directory scheme for no-script datasets: ~/.cache/huggingface/datasets/username___dataset_name/config_name/version/commit_sha
  • Backward comaptibility: cached datasets from datasets 2.15 (using the old scheme) are still reloaded from cache
