Summary0006457: Programmable filter does not work with "plain" Python
DescriptionIf you set up your paths correctly, it is possible to script ParaView with the basic python executable (as opposed to pvpython). However, one feature that never seems to work is the programmable filter. Whenever the programmable filter is created from the basic python executable, it cannot import the ParaView module.

The same process works fine in pvpython.

I cannot reproduce this on my Mac. I have the following:

I am running paraview from the build tree. My Python path is:
/Users/berk/Work/paraview3-build/bin:/Users/berk/Work/paraview3-build/Utilities/VTKPythonWrapping

When I run the following script using python, it all works fine.

from paraview import servermanager

servermanager.Connect()

source = servermanager.sources.ProgrammableSource()
source.GetProperty("Script").SetElement(0, """
from paraview import vtk
from paraview import servermanager
""")
source.UpdatePipeline()

In this example, I don't think the programmable filter script is being executed. When I add a print statement to it, nothing is printed. If I try to import "utils" rather than "util", there are no complaints.

In the first three lines of the python script I set the path explicitly, rather than relying on the PYTHONPATH.


import sys
sys.path.insert(0,'/usr/local/building/Paraview3/Utilities/VTKPythonWrapping')
sys.path.insert(0,'/usr/local/building/Paraview3/bin')

from paraview import servermanager

servermanager.Connect()


source = servermanager.sources.ProgrammableSource()
source.GetProperty("Script").SetElement(0, """
import sys
print "sys.path = ", sys.path

from paraview import vtk
from paraview import util
from paraview import servermanager
""")
source.UpdatePipeline()
