Path to CPLEX in Python

I want to use CPLEX with Python. I've added path

C:\Program Files\IBM\ILOG\CPLEX_Studio_Community129\cplex\python\3.7\x64_win64

to the system but

import cplex

it's not working.

It only works if I add the path in the program explicitly, that is:

import sys
sys.path.append('C:/Program Files/IBM/ILOG/CPLEX_Studio_Community129/cplex/python/3.7/x64_win64')
import cplex

Do you have any idea why adding the path directly to the system variables is not working?

Solution

  • Add the CPLEX path to PYTHONPATH.

    Windows: My Computer > Properties > Advanced System Settings > Environment Variables and modify it

    Linux: export PYTHONPATH="${PYTHONPATH}:/your/CPLEX/path"
