Thanks - that is exactly what I was looking for!

Hi Alan,

here is the way I do it when I code stuff in Sublime Text and directly execute code within the editor.

import sys
pv_path = '/Users/seb/work/code/ParaView/build-ninja'
sys.path.append('%s/lib' % pv_path)
sys.path.append('%s/lib/site-packages' % pv_path)

from paraview.simple import *

Hi Alan,
Are they working from a version of ParaView that used the installers? That's what I'm assuming for my next comments. For Mac I think they need to use DYLD_LIBRARY_PATH instead of LD_LIBRARY_PATH. I tried going through to do this myself and wasn't able to completely do it but was getting further along. Basically I opened a Python shell and tried manually importing the parts in servermanager.py. I'm not in front of a Mac right now so I can't point you to all of the paths I was using but basically I would add parts to the DYLD_LIBRARY_PATH and then do another import where if would give me more informative errors (things like can't find library /X/Y/Z/xxx.so).
Not a full solution but maybe enough to get you going in the proper direction.
Regards,
Andy

I have two users that wants to use ParaView paraview.simple commands from a generic version of Python (i.e., not pvpython).  Are there any tricks to getting this to work?  One user is on a Mac, the other is on Linux.  As you can see, my user is having issues even importing paraview.simple.

Here is a copy of the errors the user is having:


>import sys
>sys.path
['/Applications/paraview.app/Contents/Python', '/Applications/paraview.app/Contents/Libraries', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python26.zip', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload', '/Library/Python/2.6/site-packages', '/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/PyObjC']

>From looking at this, I added '/Applications/paraview.app/Contents/Python' and '/Applications/paraview.app/Contents/Libraries' to my PYTHONPATH.  I also made a guess at which directory to add to my LD_LIBRARY_PATH.  Unfortunately, it did not work, as you can see below:

$ echo $PYTHONPATH
:/Applications/paraview.app/Contents/Libraries/:/Applications/paraview.app/Contents/Python

$ echo $LD_LIBRARY_PATH :/Applications/paraview.app/Contents/Libraries/:/Applications/paraview.app/Contents/Python/vtk
$ python
