# 深度学习入门之PyTorch

Learn Deep Learning with PyTorch

非常感谢您能够购买此书，这个github repository包含有[深度学习入门之PyTorch](https://item.jd.com/17915495606.html)的实例代码。由于本人水平有限，在写此书的时候参考了一些网上的资料，在这里对他们表示敬意。由于深度学习的技术在飞速的发展，同时PyTorch也在不断更新，且本人在完成此书的时候也有诸多领域没有涉及，所以这个repository会不断更新作为购买次书的一个后续服务，希望我能够在您深度学习的入门道路上提供绵薄之力。

**注意：由于PyTorch版本更迭，书中的代码可能会出现bug，所以一切代码以该github中的为主。**

## 配置环境

书中已经详细给出了如何基于Anaconda配置python环境，以及PyTorch的安装，如果你使用自己的电脑，并且有Nvidia的显卡，那么你可以愉快地进入深度学习的世界了，如果你没有Nvidia的显卡，那么我们需要一个云计算的平台来帮助我们学习深度学习之旅。[如何配置aws计算平台](https://github.com/SherlockLiao/code-of-learn-deep-learning-with-pytorch/blob/master/aws.md)

## Acknowledgement

本书的第二版内容其中一些部分参考了 mxnet gluon 的中文教程，[通过MXNet/Gluon来动手学习深度学习](https://zh.gluon.ai/)。

Gluon 是一个和 PyTorch 非常相似的框架，非常简单、易上手，推荐大家去学习一下，也安利一下 gluon 的中文课程，全中文授课，有视频，有代码练习，可以说是最全面的中文深度学习教程。
