When I import EOmaps, I obtain the following import error

[yun881201]

I modified File ~\anaconda3\envs\specavail1\lib\site-packages\eomaps_shapes.py:2 like this : original 1 from matplotlib.collections import PolyCollection, QuadMesh 2 from matplotlib.tri import TriMesh, Triangulation modification 1 from matplotlib.collections import PolyCollection, QuadMesh, TriMesh 2 from matplotlib.tri import Triangulation

This solved the error problem.

[raphaelquast]

Thanks for reporting this!

I'm re-opening the issue since this is most probably an issue with the recent matplotlib v3.6 release that apparently changed the import for TriMesh... I'll have to check with the matplotlib-devs if this is intended or not...

[raphaelquast]

This is now fixed in the latest hotfix-release EOmaps v4.4.3 ... thanks again for reporting!
