小书学习的主要方向是TensorFlow和Pytorch,今天就来安装一下Pytorch。
第一步：去官网看看
Pytorch官网：(https://pytorch.org/)
点击get started
第二步：选择与自己相匹配的版本，这里显示是我安装的选择。
复制命令到win10终端：
第三步：成功安装：

谈笑间，pytorch就已经安装成功了。我这边开的热点，网速可能会快一些。
注：现在网上的教程大多是Anaconda方式 安装，谁让小书是小白呢，代码编辑器是sublime text 3,所以用的都是简单粗暴的方法。
第四步：(老规矩)测试一下：
C:\Users\Shu\Desktop>python
Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pytorch
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named ‘pytorch‘
>>> import torch
>>>
