Pipeline NLU : tensorflow_embeddings and intent_classifier_sklearn

why do we use both : tensorflow_embeddings and intent_classifier_sklearn in pipeline ? correct me if I’m wrong , as i understood , the result of tensorflow_embeddings ‘overwrite’ the result of intent_classifier_sklearn ?

Are you speaking of the provided pipelines? Only one of them uses intent_classifier_sklearn, the other uses intent_classifier_tensorflow_embedding.
