I'm trying to import numpy and other python modules so I can use them in Houdini for expressions.

I tried using the paths defined at ‘Python Script locations’, http://www.sidefx.com/docs/houdini/hom/locations.html [www.sidefx.com]
but these paths do not appear to be defined on the Mac. I launched Houdini Terminal and printenv shows

HIH=/Users//houdini16.5
HIS=/Applications/Houdini/Houdini16.5.473/Frameworks/Houdini.framework/Versions/Current/Resources/houdini

but no paths for the pythonrc.py file.

Suggestions?

Thanks,
