Matplotlib 3.1.1 impacts some visual tests
See original GitHub issueMatplotlib 3.1.1 (released on July 1, 2019) broke some of our tests, particularly the Rank2D tests with very big RMSE (~40) and very different diff images. For now in in #907 I have regenerated the baseline images for Rank2D so that our tests will pass on Travis and Appveyor, but I have not changed the tests/requirements.txt (except to note this strange behavior). Running the tests with matplotlib==3.1.0 will result in image comparison failures for Rank2D. We should investigate what the behavior is for other matplotlib versions and determine what has changed in 3.1.1 that changed the Rank2D images (but not, say, the Confusion Matrix or Classification Heatmap) so drastically.

Thanks for the speedy response @jklymak; btw the mpl team are total badasses — thank you, thank you, thank you for all you do! And thanks @nickpowersys for offering to do the PR, but I’ll go ahead and open one now since I already have a branch on my local with the repairs to the images 😉. Stay tuned!
This was a bug and should be fixed 3.1.2. Sorry about that. https://github.com/matplotlib/matplotlib/pull/14677
