The amount of generated training data

I have a bunch of intents defined in my nlu.md. The file is 241 lines long. I also have a domain.yml file and a stories.md file.

I then hit rasa train on the terminal and things start running. This is the first few lines;

Epoch 1/100
763/763 [==============================] - 1s 736us/sample - loss: 2.6756 - acc: 0.3486
Epoch 2/100
763/763 [==============================] - 0s 168us/sample - loss: 2.2360 - acc: 0.5007
Epoch 3/100
763/763 [==============================] - 0s 166us/sample - loss: 1.8602 - acc: 0.5007
Epoch 4/100
763/763 [==============================] - 0s 171us/sample - loss: 1.7426 - acc: 0.5007
Epoch 5/100
763/763 [==============================] - 0s 166us/sample - loss: 1.6763 - acc: 0.5007

I understand that these lines of code are the output from keras but I wonder … where does the number 763 come from?

@koaning That should be the number of mini-batch iterations for each epoch of Rasa Core training.

Thanks for the response!

That sounds a bit strange though. There are more mini batches than data points going into the model?
