Okay, potentially multiplied by popsize or maxiter 🙈 .

The best we can do is not showing the message during unpickling. The rest is on scipy.

It's expected that this message shows up N times for ScipyDifferentialEvolutionOptimizer(..., workers=N), because the objective is pickled there for each worker. Wouldn't consider that a bug.

The messages appear far greater than N times, e.g. using the problem from #881 and the following script.

import pypesto.petab
import pypesto.optimize

petab_yaml = 'icg_sd.yaml'
pypesto_importer = pypesto.petab.PetabImporter.from_yaml(petab_yaml)
pypesto_problem = pypesto_importer.create_problem()

optimizer = pypesto.optimize.ScipyDifferentialEvolutionOptimizer(
    options={
        'strategy': 'best1bin',
        'maxiter': 8000,
        'mutation': (0.2, 1),
        'recombination': 0.7,
        'popsize': 70,
        'init': 'latinhypercube',
        'polish': True,
        'workers': 8,
    }
)

result = pypesto.optimize.minimize(
    pypesto_problem,
    optimizer=optimizer,
    n_starts=4,
    filename=None,
)
