No module named matplotlib

[pauledd]

Hi
I use FreeCAD-0.16.6712.glibc2.17-x86_64.AppImage with gentoo.
I have git cloned this repo to ~/.FreeCAD/Mod/
Freecad shows this error message:

During initialization the error No module named matplotlib occurred in /home/paul/.FreeCAD/Mod/Animation/InitGui.py

I have installed matplotlib- 1.4.3:

>>> import matplotlib as plt
>>> plt.__version__
'1.4.3'

default install location is:

>>> plt.__file__
'/usr/lib64/python2.7/site-packages/matplotlib/__init__.pyc'

any ideas anyone?

Ok, I found that the python version in the freecad console differs (Python 2.7.6) from my system version (Python 2.7.14). Is it possible that the problem is the freecad AppImage that runs another version of python?

So I compiled the same freecad version natively under gentoo and the result is the same:
During initialization the error No module named matplotlib occurred in /home/paul/.FreeCAD/Mod/Animation/InitGui.py
I am out of ideas, I will give the freecad forum a try...
