[Paraview] pvpython and matplotlib

[Aurélien Marsan]

I did not debug this. I just didn't called matplotlib from the python shell
or programmable filter inside Paraview...

But here is a list of points you may have to check, from the python shell
inside Paraview :

   - is the TCL_LIBRARY environment variable correctly set ?
   - is there any numpy package inside the ParaviewDir/Lib/site-package
   directory ?

That said, I had strange behavior too with the 3.10.1 64 bits version of
Paraview.
Although I could correctly import numpy and scipy, the import of
scipy.signal for example failed... I didn't find any explanation to this
until yet...
