Time series ensemble is not supported?

[jmrichardson]

Will flaml support time series task ensemble? The following just chooses the best model

        self.automl.fit(
            dataframe=df,
            # time_budget=self.time_budget,
            task='ts_forecast',
            ensemble=True,
            estimator_list=['lgbm', 'extra_tree'],
            eval_method="holdout",
            split_ratio=0.3,
            retrain_full=True,
            log_file_name='automl_checkpoint.log',
            label="target",
            time_col="date",
            period=30,
        )
