Unable to load 'cnn_dailymail' dataset
Hi @talha1503, thanks for reporting.

It seems there is an issue with one of the data files hosted at Google Drive:
```
Google Drive - Quota exceeded

Sorry, you can't view or download this file at this time.

Too many users have viewed or downloaded this file recently. Please try accessing the file again later. If the file you are trying to access is particularly large or is shared with many people, it may take up to 24 hours to be able to view or download the file. If you still can't access a file after 24 hours, contact your domain administrator.
```

As you probably know, Hugging Face does not host the data, and in this case the data owner decided to host their data at Google Drive, which has quota limits.

Is there anything we could do, @lhoestq @mariosasko? This looks related to https://github.com/huggingface/datasets/issues/996
