Composite Entities: got an unexpected keyword argument 'composite_patterns_path'

[Nikolay Dmukha]

Hello.
I am trying to install rasa-composite-entites.
I have installed according to your instruction but when I start rasa train I get the exception:

Training Core model...
Traceback (most recent call last):
  File "/home/ndmukha/.pyenv/versions/3.7.0/lib/python3.7/site-packages/rasa/core/policies/ensemble.py", line 444, in from_dict
    policy_object = constr_func(**policy)
TypeError: __init__() got an unexpected keyword argument 'composite_patterns_path'

The above exception was the direct cause of the following exception:

My rasa version:

Minimum Compatible Version: 2.8.9
Rasa SDK Version  :         2.8.2
Rasa X Version    :         None

Can you help me please with fix this issue?
Thanks.

Thank you for the report.

I couldn't reproduce this training a NLU model using the example given in the repo. You seem to be training a full agent. Would you mind sharing you training configuration? Thanks!

Hello Benjamin.
Here is my config.yml:

language: ru
pipeline:
  - name: WhitespaceTokenizer
  - name: RegexFeaturizer
  - name: LexicalSyntacticFeaturizer
  - name: CountVectorsFeaturizer
    analyzer: "char_wb"
    min_ngram: 1
    max_ngram: 4
  - name: DIETClassifier
    epochs: 100
  - name: EntitySynonymMapper
  - name: "DucklingEntityExtractor"
    url: "http://localhost:8000"
    dimensions: ["time", "duration", "number"]
    locale: "ru_GB"
    timezone: "Europe/Moscow"
    timeout : 1
policies:
  - name: AugmentedMemoizationPolicy
    max_history: 4
  - name: TEDPolicy
    max_history: 4
    epochs: 300
    nlu_threshold: 0.7
    core_threshold: 0.4
    ambiguity_threshold: 0.1
    fallback_action_name: action_my_fallback
  - name: RulePolicy
  - name: rasa_composite_entities.CompositeEntityExtractor
    composite_patterns_path: composite_entity_patterns.json

composite_entity_patterns.json is in the same path as config.yml:

{
  "composite_entities": [
    {
      "name": "order_drinks",
      "patterns": [
        "@quantity cups of @black_tea_qty",
        "@quantity bottles of @water_qty",
        "@quantity @coffee_qty",
      ]
    }
  ]
}

And my order_drinks.yml:

version: "2.0"
nlu:
- intent: order_drinks
  examples: |
    - [two](quantity) cups of [black tea]{"entity":"black_tea_qty", "value":"2", "role":"order_black_tea"} and [three](quantity) bottles of [water] {"entity":"water_qty", "value":"3", "role":"order_water"}
