Hello, I'm trying to established a benders decomposition algorithm for my MISOCP, and for now, my sub problem is already a SOCP without any integer variables, but it's unbounded durning the iteration.
I found that gurobi can provide a extreme ray for the feasible cut, but var.UnbdRay does not work in my code , with the error: "AttributeError: Unable to retrieve attribute 'UnbdRay'"
I'm already set the parameter
"Dual_model.params.InfUnbdInfo = 1"
