Problems installing cplex for carveme

[arianccbasile]

Goodmorning everyone! I am trying to install cplex and carveme but I get the following error message. I am using anaconda3 with python 3.7. I think the problem is that cplex 12.8.0.0 doesn't work with my Python version but neither I manage to install an other cplex version nor I manage to install carveme on python 2.7.

Any suggestions?

Best regards, Arianna

I'm afraid there is no cplex version for python 3.7 yet. You need to install python 3.6 instead, that should solve the issue.

Oh it worked! I really can not believe it was that easy. Thx so much
