Change pip source to domestic mirror
Pip is a very easy to use third-party library installation method, but the default source can not be connected, even if sometimes, the success rate is very low, so it is more convenient to switch to a domestic mirror source.
1. Temporary use
You can add the -i parameter to the back when using pip to specify the pip source (Tsinghua University is used here)
eg:
pip install 库名 -i https://pypi.tuna.tsinghua.edu.cn/simple
2. Permanent modification:
linux:
modify ~ / .pip / pip.conf (create one if not), the content is as follows:
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
windows:
Create a pip directory directly in the user directory, such as: C: \ Users \ xx \ pip, create a new file pip.ini, the content is as follows
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
