Hi Gurobi team,

    I am facing a session error when using my academic WLS license on the high performance computing cluster of my university. The error showed:  

with gp.Model() as model:
  File "src/gurobipy/model.pxi", line 80, in gurobipy.Model.__init__
  File "src/gurobipy/gurobi.pxi", line 60, in gurobipy.gurobi._getdefaultenv
  File "src/gurobipy/env.pxi", line 70, in gurobipy.Env.__init__
gurobipy.GurobiError: Too many sessions, 5 active sessions for a baseline of 2

   For you reference, here is my license info.

   Because I need the tasks to be computed in parallel, I am wondering if I could increase the limit of the active session from 2 to maybe 10?

Best,

Yifeng
