@phosseini 
I think it is related to [1.10.0](https://github.com/huggingface/datasets/actions/runs/1052653701) release done 3 hours ago. (cc: @lhoestq )
For now I just downgraded to 1.9.0 and it is working fine.

Hi, 

updating tqdm to the newest version resolves the issue for me. You can do this as follows in Colab:
```
!pip install tqdm --upgrade
```

Hi @bayartsogt-ya and @phosseini, thanks for reporting.

We are fixing this critical issue and making an urgent patch release of the `datasets` library today.

In the meantime, as pointed out by @mariosasko, you can circumvent this issue by updating the `tqdm` library: 
```
!pip install -U tqdm
```
