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.

Is this an issue of using python 3.8.6 and pvpython expecting 2.7.5?
Thanks in advance for any suggestions.
“Clark”

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.
