RASA core versions:

rasa\_core==0.10.4 rasa\_core\_sdk==0.11.3

my code:

```
agent = Agent(domain_file, policies=[

        KerasPolicy(),
        FallbackPolicy(fallback_action_name="action_default_fall", nlu_threshold=0.65, core_threshold=0.4)])

agent.train(

        batch_size = 50,
        validation_split = 0.2)
