How can I “restart” a dataset, or reset it’s enumerator state, so I can reuse it again?

Datasets have no state: you can start iterating a dataset, stop, and restart iterating and it will start from the beginning.

Update from 2025 for streaming datasets (IterableDataset): you can checkpoint and resume the iteration, see the docs [here](https://huggingface.co/docs/datasets/en/stream#save-a-dataset-checkpoint-and-resume-iteration)
