How do I run a rasa model?
rasa shell
Check out the Rasa X docs for more details. By default this will load up the latest trained model. You can specify a different model to be loaded by using the
–model flag
. If you start the shell with an NLU-only model, rasa shell will output the intents and entities predicted for any message you enter.
