Since DatasetRegistry has been modified to

@strix_dataset.register("3D", "selflearning", "SyntheticData")
def synthetic_dataset(filelist, phase, opts):
    paass

the keyword multi_in and multi_out failed to recognize the new registration format.

    def _get_keys(self, val):

        results = []
        for d in dims:
            for key, value in self[d].items():  # now key become the framework name. value is attr dict.
                if val == value["FN"]:
                    results.append((d, key))
        return results
