<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">OK, here is what I believe is going on. If you add the build lib and build lib/site-packages directories to PYTHONPATH, ‘from paraview.simple import *’ works
in python. But, I could not get this to work from the install directory.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The linkage may be going over my head, but I believe the root cause of the issue is that there is now a directory called ...lib/paraview-4.1/site-packages/vtk,
and within there, is a file named vtkCommonCorePython.so. I suspect this file tries to open libvtkCommonCorePython27D-pv4.1.so.1, which is not located in this directory. It is actually located in ..../lib/paraview-4.1. But, if you are running out of a build
area, all of the *CommonCorePython* files are all found together in build/lib<o:p></o:p></span></p>
