It wasn't able to find the module because PYTHONPATH was only set for the terminal in which you ran the export command. You will need to set it in your .bashrc (or equivalent) to enable it for all terminals.
To see the current value from within the Python interpreter, do "import sys" and then "print(sys.path)". This shows all of the directories searched for openbabel.py. You can also edit sys.path from within Python. - Noel On Fri, 11 Jan 2019 at 02:55, Tayeb Kakeshpour <tayeb...@gmail.com> wrote: > I suggest installing openbabel through anaconda which solved a similar > issue for me.
