Bug report
Running tox on both my local environment and apparently on Travis (see #11360) causes an issue because "Matplotlib test data is not installed".
As part of #11360, I also tried to create a custom pytz testenv that invokes pytest -m pytz and it failed during test discovery because it could not find mpl_toolkits. Ideally, running tox out of the box should work, and it should also be possible to use it to run specific subsets of the tests.
Code for reproduction
