Hi,

I have a Streamlit app that was working fine, which basically loads a dataset from HF (CSV-based dataset), but now, the app is crushed and shows the following error " `NotImplementedError: Loading a dataset cached in a LocalFileSystem is not supported.`". I have no idea what causing this error.

Any ideas on how to solve this error?

Thank you.

Updating `datasets` should fix the issue

```auto
pip install -U datasets 

```
