[Paraview] Python interpreter not being created for coprocessing?

[Vanmoer, Mark W]

Hi Andy,

I set PARAVIEW_ENABLE_PYTHON to ON, is more needed? It did build pvpython, I don't know if that's separate thing entirely, though.
$ pvserver -version
paraview version 3.14.1-1549-g5f34f40

$ python -version
Python 2.6.6

$ cmake -version
cmake version 2.8.9

CMakeCache.txt is attached.

I also just noticed that ctest -R CoProcessing returns No tests were found!!!, yet it does have other tests.
Let me know what else you need.

Mark

Hi Mark,

I think I can guess what the problem is but can't be certain without some more information. My guess is that you're using ParaView 3.14.1 for this and you're trying to use the fortran interface but haven't built ParaView with Python enabled. There were some dependency issues there that have been ironed out since then though. If that's not the case though I'll need more information on versions and maybe sending your CMakeCache.txt in your ParaView build directory.

Hello,

I'm setting up someone's code to use coprocessing with OSMesa and openmpi/pgi/cuda fortran on NCSA's Forge using ParaView from the git repo. I'm getting segfaults and pgdbg gives me this error when coprocessorinitialize is called:

[0] Signalled SIGSEGV at 0x2B62188CFD9A, function vtkCPPythonHelper::GetPythonInterpretor(), file /usr/apps/vis/ParaView/repo/ParaView/CoProcessing/CoProcessor/vtkCPPythonHelper.cxx, line 136
0x2B62188CFD9A:  48 8B 41 38            movq   56(%rcx),%rax

which is:
vtkPVPythonInterpretor* vtkCPPythonHelper::GetPythonInterpretor()
{
  return Instance->PythonInterpretor;
}

The call stack is
vtkCPPythonHelper::GetPythonInterpretor() line 136 in vtkCPPythonHelper.cxx
vtkCPPythonScriptPipeline::Initialize(const char *) line 69 in vtkCPPythonScriptPipeline.cxx
coprocessorinitialize_ line 88 in FortranAdaptorAPI.cxx


So is an Instance not getting created? I have the system python in my path.

Thanks,
Mark
