Cannot preview cnn_dailymail dataset
I guess the cache got corrupted due to a previous issue with Google Drive service.

The cache should be regenerated, e.g. by passing `download_mode="force_redownload"`.

CC: @severo  Note that the dataset preview uses its own cache, not `datasets`' cache. So `download_mode="force_redownload"` doesn't help. But yes indeed the cache must be refreshed.

The CNN Dailymail dataste is currently hosted on Google Drive, which is an unreliable host and we've had many issues with it. Unless we found another most reliable host for the data, we will keep running into issues from time to time.

At Hugging Face we're not allowed to host the CNN Dailymail data by ourselves AFAIK Yes @lhoestq, I didn't explain myself well: my previous message was addressed to @severo.  I remove the tag dataset-viewer, since it's more an issue with the hosting on Google Drive Sounds good. I was looking for another host of this dataset but couldn't find any (yet) It seems like the issue is with the streaming mode, not with the hosting:

```python
>>> import datasets
>>> dataset = datasets.load_dataset('cnn_dailymail', name="3.0.0", split="train", streaming=True, download_mode="force_redownload")
Downloading builder script: 9.35kB [00:00, 10.2MB/s]
Downloading metadata: 9.50kB [00:00, 12.2MB/s]
>>> len(list(dataset))
0
>>> dataset = datasets.load_dataset('cnn_dailymail', name="3.0.0", split="train", streaming=False)
Reusing dataset cnn_dailymail (/home/slesage/.cache/huggingface/datasets/cnn_dailymail/3.0.0/3.0.0/3cb851bf7cf5826e45d49db2863f627cba583cbc32342df7349dfe6c38060234)
>>> len(dataset)
287113
```

Note, in particular, that the streaming mode is failing silently, returning 0 row while I would have expected an exception instead. The result is that the dataset viewer shows `No data` instead of a detailed error.

 Well this is because the host (Google Drive) returns a document that is not the actual data, but an error page Do you think that `datasets` should detect this anyway and throw an exception? Yes it definitely should ! I don't have the bandwidth to work on this right now though Indeed, streaming was not supported: tgz archives were not properly iterated.

I've opened a PR to support streaming.

However, keep in mind that Google Drive will keep generating issues from time to time, like 403,...
