ConverRT has been taken down from the public domain (see: GitHub - PolyAI-LDN/polyai-models). For now you’ll have to change your config file to use a different tokenizer and featurizer.

what tokenizer and featurizer should we use ? Please give some examples of config files .

Documentation for it is here: Components | Rasa Open Source Documentation

This is what I went with, but that’s only because I had spacy all ready to go. I don’t know what the advantages of one over the others is, to be honest.

pipeline:
   - name: "SpacyNLP"
     model: "en_core_web_md"
   - name: "SpacyTokenizer"
   - name: "SpacyFeaturizer"
   - name: RegexFeaturizer
   - name: LexicalSyntacticFeaturizer
   - name: CountVectorsFeaturizer
   - name: CountVectorsFeaturizer
     analyzer: "char_wb"
     min_ngram: 1
     max_ngram: 4
   - name: DIETClassifier
     epochs: 100
   - name: EntitySynonymMapper
   - name: ResponseSelector
     epochs: 100
