I do not know how to fix the following error:

"OverflowError: value too large to convert to int"

This error shows up when the model creates the objetive function (.setObjective() command). This only happens with a large instance. If I try to run a smaller instance there is not error at all.

  I don't think that this is Gurobi related. Do you use pandas? Maybe this stackoverflow post about the Error might help.

  If you think this is related to Gurobi, could you please post a minimal working example?
