cache reuse
I have downloaded wikitext by `load_dataset("wikitext", "wikitext-2-raw-v1")`, and get the cache file in `.cache/huggingface/datasets`,

then I try to copy the `huggingface/datasets` folder to the lab server to reuse but fails.

What's the proper way to reuse the cache downloaded on another pc?
You should use [`save_to_disk`](https://huggingface.co/docs/datasets/package_reference/main_classes.html?highlight=save#datasets.DatasetDict.save_to_disk) and [`load_from_disk`](https://huggingface.co/docs/datasets/package_reference/loading_methods.html?highlight=save_to_disk#datasets.load_from_disk):

```python
import datasets
# Will download and preprocess the dataset
data = datasets.load_dataset("wikitext", "wikitext-2-raw-v1")
# Save it in a folder that you can copy
data.save_to_disk("PATH/TO/FOLDER")

# On the other machine - reload the ready to use dataset from the copied folder
data = datasets.load_from_disk("PATH/TO/FOLDER")
```<|||||>thanks!
