Having completed several online courses recently, it was so pleasurable going back to hardcopy and work through François Chollet’s book Deep Learning With Python and published by Manning (which, imo do the best range of technical books). Written by the creator of the Keras deep learning library, every page was a light-bulb moment, explaining the theory and practice of neural networks so clearly (without needing to be a mathematician!) that every page was a joy to read.

Regardless of any deep learning framework you are thinking of getting into (Keras, Tensorflow, PyTorch, H2O etc), this is a great place to start.
