Comments:
Thanks for reporting, @StevenTang1998.

I'm looking into it. 

Hi @StevenTang1998,

We have fixed the issue:
- #4389

The fix will be available in our next `datasets` library release. In the meantime, you can incorporate that fix by installing `datasets` from our GitHub repo:
```
pip install git+https://github.com/huggingface/datasets#egg=datasets
```

Thanks for your reply!!
And the totto dataset has the same problem. The url should be change to [https://storage.googleapis.com/totto-public/totto_data.zip](https://storage.googleapis.com/totto-public/totto_data.zip).

Hi again @StevenTang1998,

I don't see any problem when loading `totto` dataset:
```python

   ...: ds = datasets.load_dataset("totto")

```

Sorry, I didn't express it clearly. It's the totto dataset from gem.
datasets.load_dataset('gem', 'totto')


@StevenTang1998 fixed in:
- #4396

Thanks!!
