i am trying to create a custom policy “MyPolicy” in botfront, which would just return a value.My main intention is to see whether the custom policy is getting registered in rasa or not.
below is my policy code and i have placed that in my botfront/rasa folder:
from rasa_sdk import Action, Tracker
#from rasa_sdk.events import SlotSet
from rasa_sdk.events import SessionStarted, ActionExecuted
import logging
from rasa_sdk.executor import CollectingDispatcher
from rasa_sdk.events import UserUtteranceReverted, ActionReverted
from rasa_sdk.events import SlotSet
from rasa_sdk.events import AllSlotsReset
from rasa_sdk.events import UserUtteranceReverted, ActionReverted, FollowupAction
from typing import List, Dict, Text, Optional, Any, Union, Tuple
import rasa.shared.utils.common
import rasa.shared.utils.io
from rasa.core.policies.policy import Policy, PolicyPrediction
class MyPolicy(Policy):
def __init__(
self,
lookup: Optional[Dict] = None,
**kwargs: Any,
) -> None:
# max history is set to 2 in order to capture
# previous meaningful action before action listen
super().__init__(
lookup=lookup,
**kwargs,
)
print("in policy*****************************************************************")
def predict_action_probabilities(self, tracker, domain):
if tracker.get_slot("version") == "15.9.0":
return confidence_scores_for("action_hi", 1.0, domain)
else:
return "hiiiiii"
def _metadata(self) -> Dict[Text, Any]:
return {"lookup": self.lookup}
In my policies pipeline i have the below code: policies:
- name: TEDPolicy
epochs: 50
max_history: 5
batch_size:
- 32
- 64
- name: RulePolicy
- name: AugmentedMemoizationPolicy
- name: MyPolicy
But it is throwing the below error:

@akelad Any help in this regard would be welcomed
