Utilities for working with datasets.

Functions:

  • iter_dataset –

    Iterate over a Hugging Face Dataset, yielding each 'row' as a dictionary.

iter_dataset #

iter_dataset(dataset: Dataset) -> Iterator[dict[str, Any]]

Iterate over a Hugging Face Dataset, yielding each 'row' as a dictionary.

Parameters:

  • dataset (Dataset) –

    The dataset to iterate over.

Yields:

  • dict[str, Any] –

    A dictionary representing a single entry in the batch, where each key is a column name and the corresponding value is the entry in that column for the current row.
