Also confirmed this is still the case after a pip downgrade.

Thanks! A couple of comments.

A thought for a different PR: it might be sane to symlink docs/index.md to README.md, or vice versa. They do have a diff, but it looks like only a few relative links.

Thanks! (Please don't merge this PR directly; I'll need to import it and re-export to GitHub.)

Our google3 -> GitHub export process copies the README to turn it into a home page for https://google.github.io/pytype, so yes, they are the same doc under the hood :)

If you're listing broken installs -- pytype doesn't install with Python3.7 on Ubuntu 18.04 (either native or with WSL). It works fine with Python3.6 on native Ubuntu but gives the same error message under WSL.

$ python3.7 -m pip install --upgrade --user .
