    Hi everyone,


    I have a problem when using docplex with Python 3.6 (installed through Anaconda). When I ran the program, the following error occurred:

     

    DOcplexLimitsExceeded: **** Promotional version. Problem size limits exceeded, CPLEX code=1016

     

    I have already installed CPLEX 12.8 for students so it is definitely not a promotional version.
    Has anyone encountered similar situations before? What should I do at this point?

     

    Thanks!!

    -Sharon

    This usually happens because some environment still points to the limited version.

    Make sure that PYTHONPATH etc. point to the full version of CPLEX. Even better, delete the limited version. Then you can be sure that you either use the full version or get an error like "CPLEX not found".
