TensorFlow.js 是一个开源硬件加速 JavaScript 库，用于训练和部署机器学习模型。

TensorFlow.js 0.11.1 已发布，包含大量更新：

• Add capability to save and load tf.Models using the following mediums:

• browser Local Storage

• browser IndexedDB

• browser file downloads and uploads

• HTTP requests
  See Tutorial Page for more details. (#181).
