@resmo you should remove the --python 3.6 part from run: ansible-test sanity --docker -v --color --python 3.6. This forces all sanity tests to run with Python 3.6, and potentially skips tests which do not support 3.6. Also it does not run certain sanity tests with other Python versions (like the import and compile tests).
