def add_attribute(cls: Type[AttributeType],
                  name: str,
                  local_uid: Optional[int] = None,
                  feature_node_hash: Optional[str] = None,
                  required: bool = False,
                  dynamic: bool = False) -> AttributeType

  • required - Whether the label editor would mark this attribute as ‘required’.
  • dynamic - Whether the attribute can have a different answer for the same object across different frames.
