[Paraview] [EXTERNAL] Re: paraview.simple and generic python

[Scott, W Alan]

Patrick,
I tried it before, and it failed.  I just tried it - and it worked!  I needed your hint - I was pointing to the install, rather than the build.

Thank you!

Alan

Dear Alan,
Sebastien recently posted this:

import sys
pv_path = '/Users/seb/work/code/ParaView/build-ninja'
sys.path.append('%s/lib' % pv_path)
sys.path.append('%s/lib/site-packages' % pv_path)

from paraview.simple import *

Where pv_path is the path to the ParaView build. This seems to work well for me. Can you give it a try?
Best regards,
Patrick

I have a user that wants to use ParaView from within generic python (not pvpython).  Unfortunately, I am somewhat struggling.  Does anyone have any ideas?

I am running the version of Python that was used to build ParaView (i.e., probably no version mismatch).

setenv LD_LIBRARY_PATH  .../Python-2.7.5/lib/
setenv PYTHONPATH  ....paraview-install/lib/paraview-4.1/site-packages

..../Python-2.7.5/bin/python

Python 2.7.5 (default, Jun 17 2013, 15:20:04)

    from vtkCommonCorePython import *
ImportError: No module named vtkCommonCorePython

So, my question is, where does vtkCommonCorePython come from?  There isn't a vtkCommonCorePython.py in the tree, but is a ..../lib/paraview-4.1/site-packages/vtk/vtkCommonCorePython.so.  How does this get linked in?

Thanks,

Alan Scott
