I’m trying to use paraview scripting within python3 for Ubuntu 20.04.1 LTS. If I open python3 on the command line I get the error
`$> python3
Python 3.8.2 (default, Jul 16 2020, 14:00:26)
[GCC 9.3.0] on linux
Type “help”, “copyright”, “credits” or “license” for more information.`

I have `python3-paraview` , `paraview` , `paraview-dev` , `vtk7` , `python3-vtk7` , etc installed from the synaptic installation manager. There are two files with `vtkCommonCorePython` inside the `dist-packages` directory :
`
/usr/lib/python3/dist-packages/vtk/vtkCommonCorePython.cpython-38-x86_64-linux-gnu.so
/usr/lib/python3/dist-packages/vtkmodules/vtkCommonCorePython.cpython-38-x86_64-linux-gnu.so
`
Searching the internet shows that other people have had similar problems, and solved it but including the paths to `vtkCommonCorePython` , but `sys.path` does include `/usr/lib/python3/dist-packages` , so `vtkCommonCorePython` should be found.
Can anybody see what might be missing in this case?
Many thanks! John

Hi Maruthi, I had to give up on this due to time constraints and revert to Ubuntu 18. Now, I know this could be done using a [docker](https://www.docker.com/) within Ubuntu 20.

Did you try with the pvpython executable ? This is the recommended way
