Dear community,

  Hi Lin,

  You can disable console output by setting the LogToConsole parameter to 0. To additionally disable output to a logfile, use the LogFile or OutputFlag parameters.

  Thanks,

  Eli

  You can find examples of how to set parameters for each API in the Parameter Examples section of our documentation. E.g., in Python:

  import gurobipy as gp
  
  m = gp.Model()
  m.Params.LogToConsole = 0

  To also prevent license file information from printing to the console, please see the article How do I suppress all console output from Gurobi?.

  Hi,

  In case you use Gurobi with c++, you can use the following 

  // Env and model

  GRBEnv env = GRBEnv();

  GRBModel model = GRBModel(env);

  //Avoid printing the LP solution in console
  model.set(GRB_IntParam_LogToConsole, 0);
