What is Keras?
Keras is a beautiful API for composing building blocks to create and train deep learning models. Keras can be integrated with multiple deep learning engines including Google TensorFlow, Microsoft CNTK, Amazon MXNet, and Theano. Starting with TensorFlow 2.0, Keras, the API developed by François Chollet, has been adopted as the standard high-level API, largely simplifying coding and making programming more intuitive.
