I am trying to run a python script from within MATLAB just using the system command, i.e.
[~,result] = system(['python myscript.py someInputFile.out'])
This script relys on a library (openAi gym). When I try to run this python script I get:
import gym
ImportError: No module named gym
The script works fine when I call it from the command line. My python version is the same as is used in my shell. I'm not an expert in python, but I know MATLAB launches works inside its own shell, maybe there is there something I need to do to ensure that the 'gym' module is in my python path?
I know there are more elegant ways now to integrate MATLAB and python, but I'm under a bit of time pressure and was hoping for a quick fix.
Thanks!
