李沐，亚马逊 AI 主任科学家，名声在外！半年前，由李沐、Aston Zhang 等人合力打造的《动手学深度学习》正式上线，免费供大家阅读。这是一本面向中文读者的能运行、可讨论的深度学习教科书！

之前，红色石头就分享过这份资源，再次附上：

我们知道，作为 MXNet 的作者之一，李沐的这本《动手学深度学习》也是使用 MXNet 框架写成的。但是很多入坑机器学习的萌新们使用的却是 PyTorch。如果有教材对应的 PyTorch 实现代码就更好了！

撒花！今天就给大家带来这本书的 PyTorch 实现源码。最近，来自印度理工学院的数据科学小组，把《动手学深度学习》从 MXNet “翻译”成了 PyTorch，经过 3 个月的努力，这个项目已经基本完成，并登上了 GitHub 热榜。
