Getting started with pvpython

Hello. I am so new to paraview, I am at page 12 of the Paraview Guide. I have the GUI working. However, I am asked to type from the terminal “pvpython” followed by “from paraview.simple import *”. The result is not what the book says should happen.

Python 3.8.6 (default, Jan 23 2021, 18:21:19)
[GCC 7.3.1 20180303 (Red Hat 7.3.1-5)] on linux
Type “help”, “copyright”, “credits” or “license” for more information.

from paraview.simple import *
( 83.392s) [paraview ] VisRTXBackend.cxx:42 WARN| VisRTX Error: Unsupported device

Is this an issue of using python 3.8.6 and pvpython expecting 2.7.5?

Thanks in advance for any suggestions.


Welcome to ParaView, Clark.

It’s just a warning that your system won’t support ray tracing using VisRTX. Feel free to ignore the warning.

Copy and thank you.
