[python #KDG-595508]: Problem with metpy.plots

Hello! Thanks for your question.

MetPy has run into a compatibility issue with the recently-released cartopy 
0.18 that we are aware of. In the mean time the solution is to roll back to 
cartopy 0.17 until we are able to get a fix out for MetPy 0.12.


I hope this helps!

Drew
