Я реализую форму действия для сбора всех необходимых данных для некоторой обработки, но я получил эту ошибку:
2020-04-09 09:19:13 ERROR rasa_sdk.endpoint - Failed to extract slot type with action places_form
2020-04-09 09:19:13 ERROR rasa.core.actions.action - Failed to extract slot type with action places_form
Эта пользовательская форма должна собирать два обязательных слота: city и type , Первый собран из объекта намерения. Например: Give me all places for [Rennes](city). Это прекрасно работает.
Но предыдущее намерение не содержит подсказку type и форму действия, и я хочу, чтобы был вызван дополнительный вопрос. Например: Which type of places?.
Вот код этой формы действия:
class CustomFormAction(FormAction):
def name(self):
return ""
def request_next_slot(
self,
dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any],
) -> Optional[List[EventType]]:
"""Request the next slot and utter template if needed,
else return None"""
for slot in self.required_slots(tracker):
if self._should_request_slot(tracker, slot):
# logger.debug(f"Request next slot '{slot}'")
dispatcher.utter_message(
template=f"utter_ask_{self.name()}_{slot}", **tracker.slots
)
return [SlotSet(REQUESTED_SLOT, slot)]
return None
class PlacesForm(CustomFormAction):
def name(self) -> Text:
return "places_form"
@staticmethod
def required_slots(tracker: Tracker) -> List[Text]:
return ["city", "type"]
def submit(
self,
dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any],
) -> List[Dict]:
city = tracker.get_slot("city")
print("city : {}".format(city))
print("domain : {}".format(json.dumps(domain)))
elements = requests.get("http://...").json()
dispatcher.utter_message(template="utter_places")
dispatcher.utter_message(json.dumps(elements))
return []
Вот способ, которым я определил связанную историю:
## places
* places
- places_form
- form{"name": "places_form"}
И places намерение:
## intent:places
- Give me places around [Rennes](city)
- What are the places around [Rennes](city)
- I'm looking for places around [Rennes](city)
- Give me all places for [Rennes](city)
У меня есть FormPolicy в моем config.yml файле:
policies:
- name: FallbackPolicy
nlu_threshold: 0.75
- name: AugmentedMemoizationPolicy
- name: FormPolicy
- name: MappingPolicy
- name: TEDPolicy
epochs: 20
