thanks.

Hey @akelad, thanks for your response. But i want the entity name to use it in my action and not the entity values.

One way to extract the entity type of the latest user input is by parsing the latest_message variable of the DialogueStateTracker class which contains the entire dump of the prediction from the NLU model

prediction = tracker.latest_message
entity_type = prediction['entities'][0]['entity']
