I am using Docplex in Python to solve a MIP. The model has benders annotations on it.
from docplex.mp.model import Model
mdl = (create the MIP model with benders annotations)
mdl.solve(log_output=True)
The previous code runs with no problem at all. However, if a solve the model again
mdl.solve(log_output=True)
I get CPLEX Error 1200: Index is outside range of valid values. If a remove the annotations, I can re-solve the model without any problem.
Any ideas on how to handle this situation?
note: I am solving several similar models (with the same structure, just different parameters) but I cannot afford to build a new model every time since creating the model is time-consuming.
