回退策略不适用于RASA框架

Question

我想实现两个阶段的后备策略，我遵循了这个article

这是config.yml

language: en
pipeline:
  # other policies
  - name: DIETClassifier
    epochs: 100
    entity_recognition: False
  - name: ResponseSelector
    epochs: 100
  - name: FallbackClassifier
    threshold: 0.7
policies:
  - name: TEDPolicy
    max_history: 10
    epochs: 20
  - name: AugmentedMemoizationPolicy
    max_history: 6
  - name: RulePolicy

在rules.yml中添加了规则-

rule: Implementation of the Two-Stage-Fallback 
  steps: - intent: nlu_fallback 
  - action: action_two_stage_fallback 
  - active_loop: action_two_stage_fallback

和domain.yml格式的响应

responses:
  utter_ask_rephrase:
  - text: I'm sorry, I didn't quite understand that. Could you rephrase? 

在意图上，信心告别0.23，它是在执行告别，而不是后退政策。

我是不是遗漏了什么？

我需要提几个RulePolicy的参数

- name: RulePolicy
    core_fallback_threshold: 0.3
    core_fallback_action_name: "action_default_fallback"
    enable_fallback_prediction: True

现在这个方法起作用了
