python 在安装 pytorch 的时候 , 很容易犯一个错误 , 大多数第三方库都是通过 终端 利用 pip 命令就可以安装上 , 然而 pytorch 就显示出了他的特别之处 , 如果直接 pip install 就是不行 , 因为这个安装命令需要从官网获取相对应的安装命令

**第一步：去官网看看**

官网 : [https://pytorch.org/][https_pytorch.org]

**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。**

我们首先要对自己的运行环境做出选择 , 然后人家会给咱们一个对应的安装命令 , 然后在终端执行这条命令就可以了

**第三步：成功安装：**

例如 :

C:\Users\Administrator>pip3 install http://download.pytorch.org/whl/cpu/torch-0.4.1-cp36-cp36m-win_amd64.whl

执行成功就可以用了
