Dataset Viewer issue for sst2
MEMBER
Hi @lewtun, thanks for reporting.

I have checked locally and refreshed the preview and it seems working smooth now:
```python
In [8]: ds
Out[8]: 
DatasetDict({
    train: Dataset({
        features: ['idx', 'sentence', 'label'],
        num_rows: 67349
    })
    validation: Dataset({
        features: ['idx', 'sentence', 'label'],
        num_rows: 872
    })
    test: Dataset({
        features: ['idx', 'sentence', 'label'],
        num_rows: 1821
    })
})
```

Could you confirm?

Thanks @albertvillanova - it is indeed working now (not sure what caused the error in the first place). Closing this :)

### Description

Not sure what is causing this, however it seems that `load_dataset("sst2")` also hangs (even though it downloads the files without problem):

```
Status code:   400
Exception:     Exception
Message:       Give up after 5 attempts with ConnectionError
