C2_W2_Assignment feedback - TF keras is impressive

I noticed if I run model.fit a second time, it doesn’t start over, but remembers where it was up to and further optimizes the model. I suppose it’s using the W’s and b’s for each layer that it previously optimized.
It means that I can play around with the Adam learning_rate and I’m not “wasting time”.

Also impressive is how tensorflow keras is a “well oiled” tool, and makes powerful NN’s very easy.

Hi @evoalg

TensorFlow Keras is very useful and a powerful tool to have.
