[Open Babel] Open Babel installation for PyMOL Optimize

[Ross M. <ros...@gm...>]

Hello,

I am trying to install Open Babel to use the Optimize plugin for PyMOL. I used Homebrew to install Open Babel with Python bindings (brew install open-babel --with-python@2) which seemed to run successfully. However, when I try to run import openbabel in python, I get the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named openbabel

Additionally, in PyMOL, I still get the following warning:

Optimize plug-in needs openbabel to be installed in your system, please follow the instructions at http://openbabel.org/wiki/Get_Open_Babel

I am running OS X 10.11.6. Any help would be appreciated. Thanks.
