How do I know what version of cplex I have python?
- Go to Control panel > Edit the system environment variables > Advanced > Environment Variables…>
- In the “User variables for your_name”, you’ll see “Path”. Make sure you see the path for the cplex.exe and python version you have installed the setup.py for. For example:
How to use CPLEX with python?
To start using the CPLEX Python API, set the Python path environment variable PYTHONPATH to the value of yourCplexhome/python/VERSION/PLATFORM. Setting this environment variable enables that version of Python to find the CPLEX modules that it needs to run Python commands and scripts that use the CPLEX Python API.
How to download CPLEX academic?
You can download CPLEX from IBM website, e.g., https://www.ibm.com/products/ilog-cplex-optimization-studio (and select “Try free edition”). You should create an account and then you will have access to the download link.
Is cplex free for python?

Is gurobi faster than cplex?
GUROBI is the fastest MIP solver, and gives slightly better results than CPLEX. CPLEX is a bit faster than GUROBI in terms of proving the optimal solution.
What is the difference between cplex and Docplex?
As such, it provides access to nearly all of the functionality CPLEX has to offer. Variables and constraints are identified by their indices in the matrix. docplex is an object oriented modeling API that is numpy/pandas friendly, which may be more natural to work with.
