Hello,
Scip and Cbc are optimization solvers, just like the GLPK you have installed.
They do not provide pip packages to install those:

Is my understanding correct that we cannot use those packages as their installation methods are not supported by pythonanywhere?
I found this old discussion about the CBC https://www.pythonanywhere.com/forums/topic/14364/
Best wishes,
