fatal: unable to access 'https://github.com/tensorflow/docs/': The requested URL returned error: 429

Seems that the CI is getting rate-throttled by GitHub?

@MarkDaoust @lamberta Is tensorflow-docs on Pypi? I can't find it.

[lamberta]

@vtomole No, not on PyPi but you can pip install it from the Git repo, see https://github.com/tensorflow/docs/tree/master/tools/tensorflow_docs/tools

[vtomole]

you can pip install it from the Git repo,

@lamberta That's what our CI does now, but apparently Github might be rate throttling us. Hence this issue.

I think we can install tensorflow_docs from its git archive tarball,
that should have lower demands than cloning a git repo.

Let me prepare a PR for that ...

[tanujkhattar]

I think using github tarball as a dependency is causing CI failures?

An oversight on my review: We are attempting to upload tensorflow-docs as a dev requirement because the existing setup.py doesn't remove it. Filed #5886.
