Why I’m getting the following error, what I’m doing wrong :

Hi @sten,

as the error you posted shows:

you don’t seem to have at least two different intents. Can you copy/paste your nlu.md content?

Regards Julian

nlu.md (2.6 KB)

Hi @sten,

could you please remove the ResponseSelector and try to train again?

Regards Julian

that was it , 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.

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
