Not able to access the XNLI dataset
Update: The dataset_info.json error is gone, but we have a new one instead:
```
ConnectionError: Couldn't reach https://www.nyu.edu/projects/bowman/xnli/XNLI-1.0.zip
```
I am not able to reproduce on my side unfortunately. Any idea @srush ?
When I try to access the XNLI dataset, I get the following error. The option of plain_text get selected automatically and then I get the following error.

```
FileNotFoundError: [Errno 2] No such file or directory: '/home/sasha/.cache/huggingface/datasets/xnli/plain_text/1.0.0/dataset_info.json'

Is it possible to see if the dataset_info.json is correctly placed?
