I downloaded the example from [https://gitlab.kitware.com/paraview/paraview/tree/master/Examples/Catalyst/PythonFullExample](https://gitlab.kitware.com/paraview/paraview/tree/master/Examples/Catalyst/PythonFullExample)

But I run into problems. If I use the latest paraview(5.7 on MACOS) and run with  
`pvpython fedriver.py cpscript.py`  
it says “`ImportError: No module named vtkParallelCorePython`”  
after adding \</Applications/ParaView-5.7.0.app/Contents/Python/vtkmodules\> to PYTHONPATH  
it gives  
" `import vtkPVClientServerCoreCorePython as CorePython`  
`ImportError: No module named vtkPVClientServerCoreCorePython`"

I then turn to use an old version as coprocessor.py said v4.2

I got another error:  
“ `from paraview.modules import vtkPVCatalyst as catalyst`  
`ImportError: No module named modules`”

Does anybody know if there is an up-to-date example for the lastest paraview? if not, which version should work with the example?

I am looking for a hands-on Python example to packing my 3D array to VTK and send it to Catalyst for visualization.

Thanks

problem resolved, either play what PYTHONPATH or import from paraview.modules
