I was trying to use gurobipy for optimization problem, and due to the limitation of my hardware, I used a WLS academic license with google colab. However when I ran the program, the following error emerges:

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

and the parameters of the failing models are the following:

{<gurobi.Model MIP instance Unnamed: 10953 constrs, 11100 vars, No parameter changes>, <gurobi.Model MIP instance Unnamed: 1727943 constrs, 1729802 vars, No parameter changes>, <gurobi.Model MIP instance Unnamed: 1740979 constrs, 1742844 vars, No parameter changes>, <gurobi.Model MIP instance Unnamed: 2163201 constrs, 2165280 vars, No parameter changes>, <gurobi.Model MIP instance Unnamed: 346113 constrs, 346944 vars, No parameter changes>}

 

What exactly is the limit of the academic WLS license? Is there anyone I can acquire some license that can run these model?

  Hi Sihang Li,

  There is no limit on a WLS license, and no distinction between academic and commercial when it comes to functionality or limits.

  In this case Gurobi is finding, and using, the size-limited license that comes with gurobipy instead of your WLS license.

  Please see the following article to resolve your issue:
  How do I resolve a "Model too large for size-limited Gurobi license" error?
