Suggestion: Avoid tensorboard packages without genfiles

Your current directory contains a tensorboard Python package that
does not include generated files. This can happen if your current
directory includes the TensorBoard source tree (e.g., you are in the
TensorBoard Git repository). Consider changing to a different
directory.

Next steps

Please try each suggestion enumerated above to determine whether it
solves your problem. If none of these suggestions works, please copy
ALL of the above output, including the lines containing only
backticks, into your GitHub issue or comment. Be sure to redact any
sensitive information.

Issue description

What i'm testing with:
tensorboard: git clone this repo, checkout -b 2.2
tensorflow: pip install tensorflow==2.2.0

I'm trying to run bazel test for tensorboard with the command bazel test -c opt --test_tag_filters=-webtest --test_timeout=300 --test_output=streamed //tensorboard/...
2 Tests are failing:

It will be great if anyone has the idea why these 2 tests are failing. Thank you.
