TensorFlow 2.0 has got some really cool features. It sets the eager execution mode by default. It provides a simplified workflow and uses Keras as the main API for building deep learning models. It is also backward compatible with TensorFlow 1.x versions.
To install TensorFlow 2.0, open your Terminal and type the following command:
pip install tensorflow==2.0.0-alpha0
Since TensorFlow 2.0 uses Keras as a high-level API, we will look at how Keras works in the next section.
