matplotlib import dedent error

[morvan68]

error importing dedent from basemap
see
matplotlib/basemap#494
when installing wmpg, basemap from conda-forge is too old/superceded, and clashes with matplotlib version?
fixed it with a hack of editing
basemap/proj.py, to read:
from inspect import cleandoc as dedent

Sorry for the late reply,

If anyone has this issue in the future, Denis has some fixes for this, you'll need to use an older version of matplotlib:
