I am studying machine learning hard with your book. I managed to follow up to Chapter 7, but I have not been able to solve the problems encountered in Chapter 7. I need your help. the problem is

Epoch 1/10

TypeError Traceback (most recent call last)

just had the same error and I would like to notify that someone already solved it https://github.com/PacktPublishing/Neural-Network-Projects-with-Python/issues/7
