If your image tests are failing and the images look fine, it's due to the tolerance of the comparison function.
Slight differences in platforms or image libs might generate subtly different images.
First, copy the tests/baseline_images/test_plotting/*_plot.png to a temp directory to look at later
Change GENERATE_BASELINE in tests/test_plotting.py to True
Run tests
Visually compare the new images to the old to make sure they are basically the same

Failed to mount folders in Linux guest. This is usually beacuse
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:
