[Python] How can I retrieve the gap in bi-objective MIP using Gurobi-Python

model.setParam(GRB.Param.MultiObjMethod, 2) model.setParam(GRB.Param.PoolSolutions, 10) model.optimize()

Then I have used:


gap = model.MIPGap #1 gap = abs(model.ObjVal - model.ObjBound) / abs(model.ObjVal) #2 best_bound = model.getObjective(index=0).getAttr('ObjBound') #3 best_bound = model.getAttr('ObjBound') #4 best_bound_0 = model.getAttr('ObjBoundN')[0] #5

But non of the codes works.

How to retrieve the gap?
