Error initializing graph component

See original GitHub issue

Hi, I am developing a bot with rasa and I wanted to include the component rasa_nlu_examples.extractors.FlashTextEntityExtractor.

I have added it to my configuration file which is as follows:

recipe: default.v1

language: es

pipeline:
   - name: WhitespaceTokenizer
   - name: RegexFeaturizer
   - name: LexicalSyntacticFeaturizer
   - name: CountVectorsFeaturizer
   - name: CountVectorsFeaturizer
     analyzer: char_wb
     min_ngram: 1
     max_ngram: 4
   - name: rasa_nlu_examples.extractors.FlashTextEntityExtractor
     case_sensitive: True
   - name: DIETClassifier
     epochs: 100
     constrain_similarities: true
   - name: EntitySynonymMapper
   - name: ResponseSelector
     epochs: 100
     constrain_similarities: true
   - name: FallbackClassifier
     threshold: 0.2
     ambiguity_threshold: 0.01

policies:
   - name: MemoizationPolicy
   - name: RulePolicy
   - name: TEDPolicy
     max_history: 5
     epochs: 100
     constrain_similarities: true

I have also added to my nlu file a lookup table with some countries, I add the start below as an example:

version: '3.0'
nlu:
  - lookup: pais
    examples: |
      - Afganistán
      - Åland
      - Albania
      - Alemania
      - Andorra

When using the command rasa train it trains a model and saves it in the models folder but when using rasa shell or rasa interactive it gives me the following error:

ERROR rasa.core.agent - Could not load model due to Error initializing graph component for node ‘run_rasa_nlu_examples.extractors.FlashTextEntityExtractor5’…

That makes sense to me! Do you want to open a PR for it?

Based on the error you pointed out, I think the problem is in that the country names in the file have special characters and can’t be read with this words = pathlib.Path(self.path).read_text().split("\n"), I have executed it and the same error appeared.

If I execute words = pathlib.Path(r'..\data\countries.txt').read_text(encoding='utf-8').split("\n"), it reads the file correctly.

Is it possible to add the encoding as an argument to the extractor?

Thank you! 😃
