SklearnIntentClassifier rasa 3.0

raise GraphSchemaValidationException(rasa.engine.exceptions.GraphSchemaValidationException: 1 components are missing required components which have to run before themselves: The following components require a DenseFeaturizer: train_SklearnIntentClassifier5.

The error message states that you need to include a dense featurizer in your pipeline. It’s also documented here.

You can find a description of the featurizers here followed by a list of the available featurizers. The two featurizers in your pipeline are both sparse featurizers.

I would try adding the LanguageModelFeaturizer to your pipeline.

- name: LanguageModelFeaturizer
  model_name: "bert"
  model_weights: "sentence-transformers/all-MiniLM-L6-v2"

and it works.
