Repository: huggingface/lighteval
Issue: ImportError: cannot import name 'url_to_fs' from 'fsspec'
Root cause: External Dependency Breakage

Hi

I am trying this lighteval for the first time and got struck immediately.

I tired to run this example

```
lighteval accelerate \
     "pretrained=gpt2" \
     "leaderboard|truthfulqa:mc|0|0"
```

And I got this error 
```ImportError: cannot import name 'url_to_fs' from 'fsspec' (/root/miniconda3/envs/lightevals/lib/python3.11/site-packages/fsspec/__init__.py)```


Steps to reproduce
```
git clone https://github.com/huggingface/lighteval.git
cd lighteval
pip install -e .
```

I ran into the same problem and below is my log error.
```

I would try fix this bug.
