[Paraview] pvpython and f2py

[Eric E. Monson]

Hey Peter,

Maybe the problem is that the PYTHONPATH that the programmable filter knows doesn't contain your module? 

Try adding at the beginning of your Programmable Filter:

import sys
sys.path.append('/Dir/of/your/library')

so it can see things in your library directory and see if your import statement works after that.

I don't know the "real" way, offhand, to include new directories in the PYTHONPATH of the programmable filter (i.e. I don't know if the PYTHONPATH environment variable affects the PPF).

-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:
