Rasa Open Source

I am trying to configure the embedding policy instead of KerasPolicy , MemoizationPolicy.

I am facing some error while using the new version of the core.[0.12.3]

def load(config_file: Optional[Text]) -> List['Policy']:
                        ^
SyntaxError: invalid syntax

unable to use config.yml
