If this is part of the error it is indicating that axes3d is being
imported twice, as different names. If both exist, it seems they have
a conflict. Because python is case sensitive in names,
Axes3D != axes3d.

The link seems to be indicating that there are two versions of the
library installed, and they are incompatible. Which is what the above
error also seems to be indicating. I'm not familiar with these
routines, so have no idea what is actually going on. I think this is
too complicated to solve second hand. To find the error, the code
that is failing has to be debugged to find how and why it is failing.
And then fixed. Not a trivial exercise.
Another alternative:
Did you by chance install matplotlib using pip, without --user? If you
did, you have conflicting installs from pip and rpm in the system
libraries. The pip install has to be removed. Even if you installed
a duplicate library with pip using --user, depending on your python
path it can conflict with the system libraries if it is before them,
introducing an inconsistency.
If a library exists in fedora and pip, always use the fedora library
so the system libraries remain self consistent. Only use pip for
libraries that aren't packaged in fedora, and always use --user to
install them, so they don't get installed into the system space.
