Before this PR, if the Matplotlib installed in the current environment is not the same as the source tree
boilerplate.py
is from, theAxes
/Figure
classes not taken from the correct source tree. This adds a guard to make sure this isn't the case.I have confirmed locally this prevents situations like those described in #29921
I can't think of a situation where one wants to deliberately generate
pyplot.py
from another source tree, but if there is manually specifying the other source tree as an argument toboilerplate.py
should still work.Fixes #29921.
