How to retrain model

How can i retrain model? When i run rasa train nlu --nlu data/my_data.md it seems like he’s training the model from the start?

Any thoughts about this?

Hi @very_najs. If you change the data, then rasa train will train a new model. Does this answer your question?

Ok i see. But is there a mode to retrain the data? Only with new data? Like this every time i add new data he is traning new model. Is there some kind of checkpoint?

@very_najs In order to train a model, you need to train with all of the data at the same time
