On page 212 under code listing 6.34 Preparing the training, validation and test generators, the last two lines which initialize the _valsteps and _teststeps are missing their denominators. Without dividing by the batch_size each training epoch can take close to 15 minutes.
The code from the github notebook includes the denominator -
