## Environment info
<!-- You can run the command `datasets-cli env` and copy-and-paste its output below. -->
- `datasets` version: 1.9.0
- Platform: Kaggle
- Python version: 3.7.10
- PyArrow version: 4.0.1


Comments:
This looks like an issue with PyArrow. Did you try reinstalling it ?

@lhoestq I did, and then let pip handle the installation in `pip import datasets`. I also tried using conda but it gives the same error.

Edit: pyarrow version on kaggle is 4.0.0, it gets replaced with 4.0.1. So, I don't think uninstalling will change anything.

You may need to restart your kaggle notebook after installing a newer version of `pyarrow`.

If it doesn't work we'll probably have to create an issue on [arrow's JIRA](https://issues.apache.org/jira/projects/ARROW/issues/), and maybe ask kaggle why it could fail

It works after restarting.
My bad, I forgot to restart the notebook. Sorry for the trouble!
