而且 TensorFlow 开发人员似乎正在推广 Keras，或者应该叫 tf.keras，希望将它作为 TensorFlow 2.0 中的推荐高级 API。 但是我觉得 Keras 包应该是自己独立的呀？

作者：杜伟、一鸣 今年 3 月份，谷歌在加州举办的 TensorFlow 开发者峰会（TensorFlow Dev Summit）上正式发布了 Tensorflow 2.0 Alpha 版。

At the 2019 TensorFlow Dev Summit today, Google announced a number of updates for its open-source machine learning library aimed at research and production. The TensorFlow 2.0 alpha provides a ...

TensorFlow 2.0 is now available. Google has also updated AutoML Vision Edge, AutoML Video, and Video Intelligence API.

Google announced TensorFlow 2.0 is now available for public use. The alpha version of the deep learning library made its debut this spring.

TensorFlow 2.0 will also feature eager execution by default -- this means ops will run immediately upon calling them.
