[Open Babel] Installation of OpenBabel python bindings

[Markus Birkenmeier]

Hi all,

I have a question concerning the installation of OpenBabel
python bindings on my system (Windows 7 64 bit, Python
2.7.5 64 bit). I installed OpenBabel v2.3.2 and tried to
use the installer of python bindings for my version 2.7
(http://open-babel.readthedocs.org/en/latest/UseTheLibrary/PythonInstall.html).
The installer didn’t find a python installation in the
registry and the only thing I could do is to abort the
setup. However, I also installed a numpy package. The
installer of this package recognized my python
installation. Is there a problem with the 64 bit version
of python? What can I do to solve the problem?

Best regards,
Markus

Hi all,

I installed Python bindings on the basis of
http://open-babel.readthedocs.org/en/latest/UseTheLibrary/PythonInstall.html.
I tried to test the installation with the described
commands. Here is the output:

C:\Users\Markus>obabel -V
The command “obabel” is either typed wrong or cannot be
found

That's strange. Try reinstalling the GUI and restarting your computer.

If it still doesn't work, you should add the Open Babel install
directory to the front of the PATH manually. Google how to do this for
your particular operating system (and be careful when editing the
PATH).

OB is 32-bit, and so you need to install 32-bit Python. (Note to self:
put this in the docs)
