How to run a module from another directory?

I have a python 2.7.15 project (I know, legacy reasons) living on my computer and I can run different files as a module from there:

cd /home/me/code/project
python -m path.to.module

This works fine. The problem is I am invoking these modules from another program living in another directory. Supposedly this will work if I set the PYTHONPATH.

export PYTHONPATH=/home/me/code/project
cd /home/me/code/controller
python -m path.to.module

However, this fails with: 

No module named path.to.module

This fails directly on the command line, so it has nothing to do with me invoking it from another program.

How do I invoke this module from another directory, if PYTHONPATH does not succeed?

The issue with PYTHONPATH is it changes sys.path, which is how the python interpreter searches for modules when importing modules. This is different than calling python to run a script. Unfortunately, I do not know a pythonic solution to this. One solution is to run a bash script that changes these directories for you:

Create a bash script called runModule.sh

#!/bin/sh
python -m some_module
cd path/to/other_module
python -m other_module

Make it executable

chmod -x ./runModule.sh

Then run it

./runModule.sh
