[Paraview] pvpython and f2py

[Eric E. Monson]

Hey Greg,

Thanks for passing along that info. I had forgotten the PPF had a spot for extra PYTHONPATH entries, and that's a good point about behavior under separate client/server.

So, Peter, if you're doing this from pvpython instead of the GUI, the ProgrammableFilter has a PythonPath property that you can set, too, that I had never noticed before Greg mentioned this.

Talk to you later,
-Eric

Using pvpython I can get the data I need, and using f2py I can wrap my fortran subroutine but I can only get f2py to create a .so file which pvpython doesn't seem to recognize when I try to import it as a module.  Can someone tell me how to either:
