Thanks for any suggestions.

Same error here!


Same here! My kaggle notebook stopped working like yesterday. It's strange because I have fixed version of datasets==1.1.2

I'm looking at it right now

I couldn't reproduce unfortunately. I tried
```python
from datasets import load_dataset

load_dataset("cnn_dailymail", "3.0.0", download_mode="force_redownload")
```
and it worked fine on both my env (python 3.7.2) and colab (python 3.6.9)

Maybe there was an issue with the google drive download link of the dataset ?
Are you still having the issue ? If so could your give me more info about your python and requests version ?

No, It's working fine now. Very strange. Here are my python and request versions

requests         2.24.0
Python 3.8.2

It's working as expected.  Closing the issue 

Thanks everybody.
