Keras is based on TensorFlow and Theano (machine learning framework developed by university of Montreal, Canada) the depth of the learning library, and is composed of pure python high-level neural network API, also only supports python development, it is to support rapid practice for TensorFlow or Theano encapsulation again, let us don't have to pay attention to too many low-level details and can be quickly converted to the idea as a result, Keras default backend for TensorFlow, if want to use the Theano can change by oneself,
