          Parameters
          ----------
          arg_params : dict
              Dictionary of name to value (`NDArray`) mapping.
          aux_params : dict
              Dictionary of name to value (`NDArray`) mapping.
          allow_missing : bool
              If ``True``, params could contain missing values, and the initializer will be
              called to fill those missing params.
          force_init : bool
              If ``True``, will force re-initialize even if already initialized.
          allow_extra : boolean, optional
              Whether allow extra parameters that are not needed by symbol.
              If this is True, no error will be thrown when arg_params or aux_params
              contain extra parameters that is not needed by the executor.
  
          Examples
          --------
          >>> # An example of setting module parameters.
          >>> sym, arg_params, aux_params = mx.model.load_checkpoint(model_prefix, n_epoch_load)
          >>> mod.set_params(arg_params=arg_params, aux_params=aux_params)
