Migrating from 0.x to 1.x

TensorFlow 1.x does not offer backward compatibility. This means that the codes that worked on TensorFlow 0.x may not work on TensorFlow 1.0. So, if you have codes that worked on TensorFlow 0.x, you need to upgrade them (old GitHub repositories or your own codes). This recipe will point out major differences between TensorFlow 0.x and TensorFlow 1.0 and will show you how to use the script tf_upgrade.py to automatically upgrade the code for TensorFlow 1.0.
