[Paraview] Importing paraview.simple from python

[Mohammad Mirzadeh]

Thanks Utkarsh. Two issues:

1- Looks like I have to use OS X provided python (2.7)? Using any other
python results in

Fatal Python error: PyThreadState_Get: no current thread

2- using system python I get some unresolved symbol issue with MPI.

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/Applications/paraview.app/Contents/Python/paraview/simple.py",
line 39, in <module>

    import servermanager

  File
"/Applications/paraview.app/Contents/Python/paraview/servermanager.py",
line 55, in <module>

    from vtk.vtkPVServerImplementationCore import *

  File
"/Applications/paraview.app/Contents/Python/paraview/vtk/vtkPVServerImplementationCore.py",
line 9, in <module>

    from vtkPVServerImplementationCorePython import *

ImportError:
dlopen(/Applications/paraview.app/Contents/Libraries/vtkPVServerImplementationCorePython.so,
2): Symbol not found: _MPI_Group_size

  Referenced from:
/Applications/paraview.app/Contents/Libraries/libmpich.3.3.dylib

  Expected in: flat namespace

 in /Applications/paraview.app/Contents/Libraries/libmpich.3.3.dylib

Any idea why that happens? I have open-mpi installed system-wide
(/usr/local).
