Keras 2: Big change to the API vs what's in lectures for part 1 fall 2016

Part 1 (2017)

Hello @Robi

Thank you for providing a link to the source. I am running into all sorts of issues and will check out your repository. For instance, the most recent issue I am facing:

C:\Users\redact\Downloads\fast.ai\deeplearning1\nbs\vgg16.py:213: UserWarning: The semantics of the Keras 2 argument steps_per_epoch is not the same as the Keras 1 argument samples_per_epoch. steps_per_epoch is the number of batches to draw from the generator at each epoch. Basically steps_per_epoch = samples_per_epoch/batch_size. Similarly nb_val_samples → validation_steps and val_samples → steps arguments have changed. Update your method calls accordingly.
validation_data=val_batches, nb_val_samples=val_batches.nb_sample)
C:\Users\redact\Downloads\fast.ai\deeplearning1\nbs\vgg16.py:213: UserWarning: Update your fit_generator call to the Keras 2 API: fit_generator(<keras.pre..., validation_data=<keras.pre..., steps_per_epoch=0, epochs=1, validation_steps=8)
validation_data=val_batches, nb_val_samples=val_batches.nb_sample)

The update from @eljas on Apr 9 from here Keras 2 Released has helped until this roadblock
