Description
It sounds like pytest-pep8 is no longer compatible with the last version of pytest (6.0.1) and is no longer maintain.
From the Travis job test https://travis-ci.org/github/larray-project/larray/jobs/721340978 of my last PR (PR #888), one can read the error message:

The command "pytest" exited with 2.
Since pytest-pep8 is no longer maintain, I don't think we do anything except force to downgrade the used version of pytest but this workaround will not last forever and I don't like to get stuck with old stuff.
I suggest to replace pytest-pep8 by pytest-flake8 which provides an option flake8-ignore similar to the option pep8ignore of pytest-pep8.
@gdementen What do you think?
