Comment 7 for bug 1833685

Hello Sebastien,

I am struggling to replicate this. Do you still have a failure in your environment if you use tox -e py37 ?

If I use our standard testing docker container, based on 18.04, the tests all pass fine for Python 3.7 (3 warnings). If I modify the testing docker to be based on 19.04 (and remove the Python 3.6 dependencies -- see attached), again the Python 3.7 tests pass with 3 warnings.

Could there be something else in your environment causing this? Or missing dependencies that are in the Dockerfile?
