Something is wrong with our python configuration for notebooks in the current container. Since MsPASS is using jupyter lab the documented way to enable interactive zoom and pan with matplotlb graphics is to use the incantation:
%matplotlib widget
When I use that I get this exception message that indicates a configuration issue:

ModuleNotFoundError: No module named 'ipympl'
Somehow we need to have ipyml, at least, installed in the container.
