I've been informed that my previous gurobi license should be reinstalled while connected to the university network. due to the error below. 

---------------------------------------------------------------------------
GurobiError                               Traceback (most recent call last)
<ipython-input-5-4b5bdce5b8bd> in <module>
    102 
    103 model.setObjective(obj,gp.GRB.MINIMIZE)
--> 104 model.optimize()
    105 
    106 #P = model.getAttr("X")

src/gurobipy/model.pxi in gurobipy.Model.optimize()

GurobiError: Model too large for size-limited license; visit https://www.gurobi.com/free-trial for a full license

after connecting myself with the university network and reinstalling the below message says that there is an inconsistency in the environment. Is there a way to solve this?

  Hi Olivia!

  Apparently, there is something off with your conda environment. It's pretty difficult to diagnose this issue and my suggestion would just be to set up a new environment.

  Please note that the conda and pip installation packages of Gurobi always include a size-restricted license, so users can get started right away. You need to use your proper academic license to handle arbitrary-sized models and have full access to Gurobi.

  Cheers,
  Matthias
