What I've tried so far I use VPN, but It was useless at the time

It would be nice if... Could we have done anything to make things better (documentation, etc.)?

If you are in the mainland of China, GCS cannot be accessed inside thanks to firewalls.

But datasets(i tried MNIST, COCO) can be downloaded without GCS authetication. Just change _is_gcs_disabled = True as stated in this issue.
