LearnerGroup.get_metadata() → Dict#

Returns JSON writable metadata further describing the implementing class.

Note that this metadata is NOT part of any state and is thus NOT needed to restore the state of a Checkpointable instance from a directory. Rather, the metadata will be written into self.METADATA_FILE_NAME when calling self.save_to_path() for the user’s convenience.
