provide executable path docplex

[Amin0G]

Hi,
I am using docplex.mp.model to create a mixed-integer programming model. Since I am using a cluster, I need to provide the path to binary executable to docplex so that docplex can recognize cplex. Is there a way to do that?
Thanks.

Hello,

DOcplex does not need the cplex.exe executable, only the thin Python/C wrapper layer.
This article explains the various options to setup the API:

Personally, I would choose the PYTHONPATH option, because you have full explicit control of what happens.
For example, on a Windows machine, assuming you have installed a Cplex Studio distribution in the directory,
and run Python version 3.8
you need to add
<CplexHome>/python/3.8/x64_win64/

to your PYTHONPATH variable.
