Summary0000455: ImportError: No module named vtkCommonPython
DescriptionOn a Ubuntu 11.10, I have installed OpenFOAM and paraview as per the instructions on openFOAM's website, using the given Ubuntu package file for openFOAM. Further, I have installed pyFOAM.

paraFOAM seems to start and produces plots, but when I start my python shell within paraview, I get the following:

==
Python 2.7.2+ (default, Oct 4 2011, 20:41:12)
[GCC 4.6.1] on linux2
>>> from paraview.simple import *
Traceback (most recent call last):
  File "<string>", line 4, in <module>
  File "/opt/paraviewopenfoam3120/lib/paraview-3.12/site-packages/paraview/servermanager.py", line 43, in <module>
    import paraview, re, os, os.path, new, sys, vtk
  File "/opt/paraviewopenfoam3120/lib/paraview-3.12/site-packages/paraview/vtk/__init__.py", line 1, in <module>
    from vtkCommonPython import *
ImportError: No module named vtkCommonPython
==

Ideally, I would want to use paraview in batch mode to output results/images using pyFoamPVSnapshot.py, but when I launch this, I get:

===
rachelm@ubuntu:~/OpenFOAM/ram-2.1.0/run/tutorials/incompressible/icoFoam/cavity$ python pyFoamPVSnapshot.py
Traceback (most recent call last):
  File "pyFoamPVSnapshot.py", line 3, in <module>
    from PyFoam.Applications.PVSnapshot import PVSnapshot
  File "/usr/local/lib/python2.7/dist-packages/PyFoam/Applications/PVSnapshot.py", line 13, in <module>
    from PyFoam.Paraview.ServermanagerWrapper import ServermanagerWrapper as SM
  File "/usr/local/lib/python2.7/dist-packages/PyFoam/Paraview/__init__.py", line 15, in <module>
    from paraview import servermanager
  File "/usr/lib/python2.7/dist-packages/paraview/servermanager.py", line 43, in <module>
    import paraview, re, os, os.path, new, sys, vtk
  File "/usr/lib/python2.7/dist-packages/paraview/vtk/__init__.py", line 1, in <module>
    from vtkCommonPython import *
ImportError: No module named vtkCommonPython
====

On linux, I then try: locate vtkCommonPython, for which I get:

==
rachelm@ubuntu:~/OpenFOAM/ram-2.1.0/run/tutorials/incompressible/icoFoam/cavity$ locate vtkCommonPython
/opt/paraviewopenfoam3120/lib/paraview-3.12/libvtkCommonPythonD.so
/opt/paraviewopenfoam3120/lib/paraview-3.12/libvtkCommonPythonD.so.pv3.12
/usr/lib/libvtkCommonPythonD.so
/usr/lib/libvtkCommonPythonD.so.5.6
/usr/lib/libvtkCommonPythonD.so.5.6.1
==

This means that no such file vtkCommonPython is present. I have added all relevant dir's to python's path (sys.path.append in site.py), but it does not seem to make any difference. I even tried a fresh install, and I get the same errors.

This seems to be an installation bug?

My OF is 2.1 and my paraview is 3.12

Did you compile ParaView with python?

Re: pyFoam - this is not supplied/supported by the official distribution

Hi Andy, No, I did not do any specific compilation for ParaView with python. I installed it off the Ubuntu deb found on OpenFOAM's website. Could you let me know how you compile paraView with python in this case? Thanks. Rachel M

I'm afraid that python support is not enabled by default in our deb packs - you will need to compile ParaView from source.

We supply a helper script called makeParaView which can be found in our 3rd party sources. Using this script, simply add the '-python' option. To see the available options, use the '-help' option.
