I've searched for a way to suppress the `Warning for adding constraints: zero or small (< 1e-13) coefficients, ignored` but no successful code so far. Anyone can help me? My code snippet which rises the warning is as follows:

import pyomo.environ as pye
pye.SolverFactory('gurobi_persistent').set_instance(model)

  You can use a gurobi.env file to set OutputFlag or LogToConsole to 0 as described as the second option in How do I suppress all console output from Gurobi?

  Managing the Gurobi environment and setting parameters before it starts, can now be done in pyomo as follows:

  import pyomo.environ as pye
  options = {"OutputFlag": "0"}
  pye.SolverFactory('gurobi_persistent', manage_env=True, options=options).set_instance(m)
