使用pip来安装python包有时候安装起来会非常慢，因此需要换成国内的源来加速下载：

#### 1.使用命令（以Torch为例） ####

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple torch

#### 2.常用的国内的源： ####

清华大学：[Simple Index][]

中国科学技术大学：[Simple Index][Simple Index 1]

阿里云：[Simple Index][Simple Index 2]

豆瓣 ：[Simple Index][Simple Index 3]

华中理工大学：[http://pypi.hustunique.com/][http_pypi.hustunique.com]

山东理工大学：[http://pypi.sdutlinux.org/][http_pypi.sdutlinux.org]

#### 3.出现无法连接： ####

WARNING: The repository located at pypi.doubanio.com is not a trusted or secure host and is being ignored. If this repository is available via HTTPS we recommend you use HTTPS instead, otherwise you may silence this warning and allow it anyway with '--trusted-host pypi.doubanio.com'.  
 ERROR: Could not find a version that satisfies the requirement opencv-python (from versions: none)  
ERROR: No matching distribution found for opencv-python

可以将源中的http改为https

#### 4.需要user： ####

Could not install packages due to an EnvironmentError: \[Errno 13\] Permission denied: '/anaconda3/lib/python3.7/site-packages/llvmlite-0.28.0.dist-info'  
Consider using the \`--user\` option or check the permissions.

需要加上--user：pip install <module> 改为 pip install --user <module>

pip install --user -i https://pypi.tuna.tsinghua.edu.cn/simple torch
