Cplex And Python 3.7

I'm trying to use cplex with python version 3.7.3. CPLEX has a setup.py for version 3.7, but when I try to use it I still get the error 'CPLEX 12.9.0.0 is not compatible with this

Solution 1:

Let's assume the Python 3.7 executable is located at C:\Python37\python.exe and CPLEX 12.9 is installed at C:\Program Files\IBM\ILOG\CPLEX_Studio_Community129. Then, to install the CPLEX Python API, you would do something like the following:

cd "C:\Program Files\IBM\ILOG\CPLEX_Studio_Community129\cplex\python\3.7\x64_win64\"C:\Python37\python.exe setup.py install

The installation instructions for the CPLEX Python API can be found here.

Solution 2:

Yes,

To my knowledge for the optimization solvers CPLEX and DOCPLEX you need to downgrade to Python 3.6 currently.

Solution 3:

I myself had to downgrade to Python 3.6 because I had the same problem but that was because Python 3.7 is 32-bit and the CPLEX API requires 64-bit (I can't tell you why, but that's just what I learned). Once you install Python 3.6 64-bit then you can download the CPLEX and DOPLEX packages so easily you'll hate that you didn't do it in the first place.
