1.1 Windows configuration pip download source
Create a pip directory in the c:\user\username directory, create a new pip.ini file in the directory, and enter the following content:
In the C:\Users\Administrator\pip\pip.ini file, what I configured is:
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

[global]
index-url = https://mirrors.aliyun.com/pypi/simple/
[install]

When using the third-party package, if Tsinghua Source is configured, it will automatically download from this address.

[root@~]# mkdir ~.pip
[root@~]# vim ~.pip/pip.conf
[root@~]# cat ~/.pip/pip.conf

index-url = https://pypi.tuna.tsinghua.edu.cn/simple

Use pip config set global.index-url to directly specify the URL of the download source, so you don’t have to manually modify the configuration file.
