TensorFlow 2.0 focuses on simplicity and ease of use. It features Keras as the core API for building and training models using eager execution. It also improves support for deploying models to production on devices like mobile and embedded systems. Researchers can further experiment using new features like ragged tensors and TensorFlow Probability. While some APIs are being removed or renamed, there will be tools to assist migrating code from TensorFlow 1.x to 2.0.
