What is the relationship between Keras and TensorFlow?
Keras is an advanced neural network API that is designed to be user-friendly and easy to use, while also supporting fast experimentation. Originally written by François Chollet, Keras is now part of TensorFlow as its high-level API. Therefore, the relationship between Keras and TensorFlow is that Keras can run on TensorFlow and integrate well with TensorFlow’s capabilities. Since TensorFlow 2.0, Keras has become the default high-level API for TensorFlow.
