Hello, all!

My computer doesn’t have internet connection. So I have to first download dataset on another computer and copy the dataset to my offline computer.

I use the following code snippet to download wikitext-2-raw-v1 dataset.

```nohighlight
from datasets import load_dataset
datasets = load_dataset("wikitext", "wikitext-2-raw-v1")

```

And I found that some cached files are in the `~/.cache/huggingface/` 's sub dirs.

In the `~/.cache/huggingface/modules/datasets_modules/datasets/wikitext/a241db52902eaf2c6aa732210bead40c090019a499ceb13bcbfa3f8ab646a126` dir I can see:  
` __init__.py`, ` __pycache__ `, `dataset_infos.json`, `wikitext.json`, `wikitext.py`

In the `~/.cache/huggingface/datasets/wikitext/wikitext-2-raw-v1/1.0.0/a241db52902eaf2c6aa732210bead40c090019a499ceb13bcbfa3f8ab646a1 26` dir I can see:  
LICENSE dataset\_info.json wikitext-test.arrow wikitext-train.arrow wikitext-validation.arrow

Do I have to copy all those files to the offline computer? Can I change `a241db52902eaf2c6aa732210bead40c090019a499ceb13bcbfa3f8ab646a126` to other names?

Or how to change those `arrow` files to `csv` files?

Hi! You only need the `arrow` files, but instead of looking for them in cache, it’s more convenient to save the dataset to disk with `save_to_disk` and transfer the generated folder to another computer, where you can simply load the dataset with `load_from_disk("path/to/folder")`.

> Or how to change those `arrow` files to `csv` files?

You can use `Dataset`’s `to_csv` method for that.
