Interactively doing  save_to_disk and load_from_disk corrupts the datasets object?
Hi,

Can you give us a minimal reproducible example? This [part](https://huggingface.co/docs/datasets/master/processing.html#controling-the-cache-behavior) of the docs explains how to control caching.
 dataset_info.json file saved after using  save_to_disk gets corrupted as follows.

Is there a way to disable the cache that will save to /tmp/huggiface/datastes ? 
I have a feeling there is a serious issue with cashing.
