Multiprocess with only one process

What is the purpose of opening 1 process if you're blocked until that process ends?

Why not simply

   def solver_func(self,arm,n_units):
        trainer = DartsTrainer(arm)
        trainer.epoch = arm['epochs']
        return  trainer.train_epochs(n_units)

    def run_solver(self, arm, n_units):
        n_units = max(n_units - arm['epochs'], 0)
        logging.info('Training arm %d for %d epochs' % (arm['seed'], n_units))
        result = self.solver_func(arm, n_units))
        arm['epochs'] += n_units
        return results[0], results[1], results[2]

Thanks
