If the variable already contains a path, add a semicolumn before adding the cplex path, otherwise, just copy-paste the cplex location to the newly created varaible value. In the variable name, add yourCplexhome/python/pythonVERSION/PLATFORM.If PYTHONPATHis among the variable, edit it, otherwise create a new varaible and name it "PYTHONPATH".In the windows Start Search, type "env" and select "Edit the system environment variables" then click "Environment Variables".
#INSTALL CPLEX IN MAC INSTALL#
Open a cmd and navigate to yourCplexhome/python/pythonVERSION/PLATFORM (it should be like C:\Program Files\IBM\ILOG\CPLEX_Studio129\cplex\python\3.7\圆4_win64, there should be the script setup.py simply run this: python setup.py install Greatly appreciate your kind advice on the above!įirst of all, you need to be able to use CPLEX from Python scripts.Īfter installation of CPLEX in your machine, you have two ways to install CPLEX-Python modules:

With regards to 3 and 4, how does one invoke Cplex from Pyomo via coding the path with the code itself? On the other hand, even without explicitly coding the path, is invoking the SolverFactory sufficient? Or is it necessary to set the path via the Anaconda Prompt? I would like to enquire if the instructions found from the IBM support site is sufficient for setting up the Cplex executable. One can either set the path within windows so that Pyomo would automatically locate the Cplex executable upon being invoked by the SolverFactory, or one can code the path within code itself. The Cplex executable is different from the API as the API is just a wrapper that translated Python instructions into C instructions during execution, and the Cplex executable is invoked specifically by Pyomo. I understand the Academic Version of CPLEX is downloadable, and that one needs to just download and click for installation. I would specifically like to enquire about the following (Kindly correct me if I am wrong):
Having trawled the net, to the best of my knowledge, I am unable to locate any comprehensive instructions on it.
I am able to install Pyomo from the instructions from the Pyomo Documentation site, but am stuck at the CPLEX portion as it is not mentioned within the site. After which, I am planning to use Pyomo to code my MIP model and invoke CPLEX from it. I have just installed Anaconda and am intending to use Spyder as it is able to display variable, parameter values for debugging.
