'utf-8' codec can't decode byte 0xff in position 0: invalid start byte
Hello, there. I downloaded a dataset in Hub and saved it to a local folder. However I could not reload it. Here is my codefrom datasets import load_dataset
raw_datasets = load_dataset("roneneldan/TinyStories")
raw_datasets.save_to_disk("Tiny_Stories")
raw_datasets = load_dataset('text', data_dir = "Tiny_Stories")Here is my error.UnicodeDecodeError                        Traceback (most recent call last)

The above exception was the direct cause of the following exception:

DatasetGenerationError: An error occurred while generating the datasetAnyone can help?

Hi!save_to_diskdoesn’t save a dataset as a text file (writes Arrow and JSON metadata files), hence the error. Instead, useload_from_disk("Tiny_Stories")to load the dataset.

Thank you very much! It is the problem of ‘file formats’. That really helps me a lot!
