In view of the slow download of the pip install installation package, the main direct installation of pip install is to pull the installation package from abroad.
The solution is to add a domestic mirror, such as Baidu https://mirror.baidu.com/pypi/simple
pip install lac -i https://mirror.baidu.com/pypi/simple
For example, Tsinghua mirror: https://pypi.tuna.tsinghua.edu.cn/simple
pip install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple
How to speed up pip download
The reason why pip is slow is that it uses a unified foreign download source by default, so if you want to speed up the download speed of pip, a feasible way is to switch the download source to domestic. Some large domestic companies also provide corresponding competing websites.

If you want to do it once and for all, maybe
alias pyinstall='pip install -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com '

After putting this alias in /etc/bash.bashrc or ~/.bashrc, you can no longer add the following parameters when calling pyinstall, and the word install is also omitted.
