需要安装pytorch，尝试了几次还是失败。同时，由于pytorch比较大，下载速度也比较慢，在这里总结快速安装pytorch步骤，以拱自己以后参考和同行参考。

# 一 安装清华镜像 #

在自己C盘这个路径下（C:\\Users\\1112\\AppData\\Roaming），主要是在AppData\\Roaming这里，用户（1112）每个电脑可能不同（我的是win10）。然后新建文件夹pip,如下图：

然后在pip文件夹里面新建文本文档pip.ini，里面内容为：

[global]
    timeout = 6000
    index-url = https://pypi.tuna.tsinghua.edu.cn/simple
    trusted-host = pypi.tuna.tsinghua.edu.cn

然后另存为文件pip.ini（格式为所有格式，不是文本类型，这里容易弄错）

成功以后会变为配置文件，在以后用pip安装包时，默认使用清华镜像，速度很快

# 二 安装pytouch #

## 成功做法： ##

pip install torch==1.2.0+cpu torchvision==0.4.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

###  不到30秒就安装成功（使用镜像的好处） ###
