All attempts to get a Google authentication bearer token failed, returning an empty token.

I also tried the tfhub.ipynb on my Ubuntu20.04 machines and still can't get the pretrained layer from tf-hub thru google storage. The error is:

Are there any authentications required to use on local machines but not on colab?

Since I haven't created any authentication key on cloab, I thought this google cloud storage is public and didn't require an authentication key, right?

No, it is wrong.

Another solution is set all try_gcs=False

No, it is wrong.

It's a little bit odd that it works on another Linux server without adding an authentication key.

Tks! This indeed works.
