Rasa NLU) Do I need to train whole intents again when I add new intents?

Question

Whenever I add new intents, Do I need to train whole intents and data again?

Or Is there any partial, continuous training instead of from scratch.

Because It takes too much time for training whole data, and get longer and longer.

I found some article and it said retraining all the time is good.

But it is 2 years ago. Retraining and updating an existing Rasa NLU model

Answer 1

yes, currently you need to retrain all the time
