Increase download speed: By changing to a faster source, you can speed up the download speed of the package.

Pip source change can be completed through the following steps:

Add a new source to the pip configuration file. New sources can be specified by editing the ~/.pip/pip.conf file or using the requirements.txt file in the project.

pip install -i <new_source> <package_name>

Common pip source changing methods include:

Use domestic sources, such as Douban and Alibaba Cloud wait. These mirror sources usually provide faster download speeds and more stable network connections.
