Disable logging to Console when Running Environments in Parallel

Hi, 

I am currently working on a Dantzig-Wolfe decomposition in Python, where at each stage, I have several independent subproblems that I solve in parallel. The code runs as it should. However, as each process is started, the following prints to the console: 

Set parameter Username

As I have understood it, Gurobi starts a new environment when starting a new process. I have therefore tried the following inside the function solve_sp that is called in parallel, as suggested in this post https://support.gurobi.com/hc/en-us/articles/360044784552-How-do-I-suppress-all-console-output-from-Gurobi.

with gp.Env(empty=True) as env:
    env.setParam('OutputFlag', 0) 
    env.setParam('LogToConsole', 0)
    env.start()

        with DantzigWolfeSP( 
            ...,
            env=env
        ) as sp:

            sp.build(...)
            sp.optimize()

            sp.write(self._results_path+f'dantzig_wolfe/sub/column_{next(self.subproblem_counter)}.sol')

            return SOLUTION

 Where DantzigWolfeSP inherits from gp.Model().

The code that executes the parallel processes looks like this: 

with ProcessPoolExecutor() as executor: 
    #Submit all subproblems to the executor

    futures = [executor.submit( 
        self.solve_sp, 
        mab_duals, 
        yearly_production_duals, 
        tanks_in_use_duals, 
        dp, 
        CNS.DEFAULT_MEAN,
        0 
    ) for dp in self._deployment_periods[:-3]] 

    # Process results as they complete 
    for future in as_completed(futures): 
        obj_rc, obj_sol, x_bar, e_bar, n_bar, *_ = future.result() 
        # Non-improving extreme-point 
        if obj_rc is None or obj_rc <= 0: 
            continue 
        self.add_extreme_point(x_bar, e_bar, n_bar, obj_sol) 
        extreme_point_added = True

However, this does not stop the logging to the console. 

I also tried creating a gurobi.env file specifying the parameters LogToConsole and OutputFlag. This removed the logging of Academic licence, but not Set parameter Username. 

Any idea how I can suppress the logging to console?

Thank you in advance.
