Hi @sten , as the error you posted shows: [image] sten: 2019-11-01 14:38:36 ERROR rasa.nlu.classifiers.embedding_intent_classifier - Can not train a classifier. Need at least 2 different classes. Skipping training of classifier. you don’t seem to have at least two different intents. Can you copy/paste your nlu.md content? Regards Julian

Hi @sten , could you please remove the ResponseSelector and try to train again? Regards Julian

that was it :frowning: , btw i would need it for FAQ handling quick question : if I have multiple *.md files in /data, does rasa train pick them up … or there is some way to point them

Hi @sten , glad that I could help. You actually didnt define any response intents (they need to be provided in a special way) but used their classifier which would not work. Jeah - rasa picks those files together. Regards Julian

i have responses.md file how do i make it work with ResponseSelector ? I followed : [image] Integrate response retrieval models in assistants built with Rasa How to easily handle single turn interactions within rasa using response retrieval models.

I have same question ,can you tell me how to make it work?

as far as I can remember you probably have #intent which have only one item …

 #intent: abc
 - abcd

should have more than one :

#intent: abc
 - abcd
 - defg
