NotImplementedError: Loading a dataset cached in a LocalFileSystem is not supported

Advertisements

I try to load a dataset using the datasets python module in my local Python Notebook. I am running a Python 3.10.13 kernel as I do for my virtual environment.

I cannot load the datasets I am following from a tutorial. Here’s the error:

---------------------------------------------------------------------------

      6 )
      7 data

NotImplementedError: Loading a dataset cached in a LocalFileSystem is not supported.

How do I resolve ? I don’t understand how this error is applicable, given that the dataset is something I am fetching and thus cannot be cached in my LocalFileSystem in the first place.

>Solution :

Try doing:

pip install -U datasets

This error stems from a breaking change in fsspec. It has been fixed in the latest datasets release (2.14.6). Updating the installation with pip install -U datasets should fix the issue.

if you are using fsspec then do:

pip install fsspec==2023.9.2

There is a problem with fsspec==2023.10.0
