How do you save an IterableDataset to disk?

[John6666]

It seems that it is necessary to convert it to a normal Dataset first.

'datasets.iterable_dataset.IterableDataset' to 'datasets.dataset_dict.DatasetDict'

how can i convert <class ‘datasets.iterable_dataset.IterableDataset’> into <class ‘datasets.dataset_dict.DatasetDict’>
