Hi,

I'm getting the following warning when I try to solve using Gurobi in pulp:

warnings.warn('GUROBI_CMD does provide good solution status of non optimal solutions')

I checked for the solution status. It was optimal. I've recently updated gurobi to 9.5.0. Can that be a reason for this warning?

Thanks

  Hi Sashank,

  Usually, this can happen if the model is infeasible or unbounded. Could you please show the Gurobi output?
  Be sure to use the latest PuLP version 2.6.

  Best regards,
  Mario
