Hello,

I am using Paraview to build a filter plugin for my university research project.  
I built Paraview 5.8.1 from [source] ([ParaView/Documentation/dev/build.md at master · Kitware/ParaView · GitHub](https://github.com/Kitware/ParaView/blob/master/Documentation/dev/build.md)) which has Python 3.7. I was first trying to use ‘Programmable Filter’ to get an idea, so I  
wrote a script in Programmable filter that starts with

import tensorflow as tf  
import keras  
import numpy, vtk

…  
When I apply the filter, ParaView crashes with Segmentation Fault. So, I just opened a Python Shell in Paraview, and tried ‘import tensorflow’ and it crashed with this error:

**Loguru caught a signal: SIGSEGV**

( 5.393s) [paraview] :0 FATL| Signal: SIGSEGV  
**Segmentation fault (core dumped)**

Then, I tried to check if I’m in the same environment in ParaView interpreter (PvPython) and Python in command line.

**In command line (conda env para has tensorflow v2.3 installed):**

> > > import sys  
> > > sys.path  
> > > [‘’, ‘/home/drishti/anaconda3/envs/para/lib/python37.zip’, ‘/home/drishti/anaconda3/envs/para/lib/python3.7’, ‘/home/drishti/anaconda3/envs/para/lib/python3.7/lib-dynload’, ‘/home/drishti/anaconda3/envs/para/lib/python3.7/site-packages’]

**In Paraview python shell (./paraview/paraview\_build/bin/pvpython)**:

> > > sys.path  
> > > [‘’, ‘/home/drishti/paraview/paraview\_build/lib/python3.7/site-packages’, ‘/home/drishti/anaconda3/envs/para/lib/python37.zip’, ‘/home/drishti/anaconda3/envs/para/lib/python3.7’, ‘/home/drishti/anaconda3/envs/para/lib/python3.7/lib-dynload’, ‘/home/drishti/anaconda3/envs/para/lib/python3.7/site-packages’]

And then, I tried ‘import tensorflow’ in both python. In ./pvpython, it crashes with the same segmentation fault, and in my normal command line python, it works.

However, in my paraview/paraview\_build/bin/ directory, I also saw another executable ./pvtkpython, when I tried running it, it opens a python interpreter, and ‘import tensorflow’ works in this one.  
I tried creating a symbolic link so that pvpython points to pvtkpython. But, that doesn’t solve the issue, and Paraview crashes again at import tensorflow.

How can I fix this issue?
