What to do if pip download is slow

Solutions include changing the mirror source, using proxy tools, using acceleration tools, using local cache, etc. Detailed introduction: 1. Change the mirror source: By default, pip will download packages from the official package index (PyPI). However, due to network reasons, official sources may be slower to access domestically. Domestic mirror sources can be used to speed up downloads. Commonly used domestic image sources include Tsinghua University, Alibaba Cloud, Douban, etc. You can use the -i parameter in the pip command to specify the image source; 2. Use proxy tools, etc.

The operating system for this tutorial: Windows 10 system, Python version 3.11.4, Dell G3 computer.

If pip download speed is slow, you can try the following methods to speed up:

1. Change the mirror source: By default, pip will download packages from the official package index (PyPI). However, due to network reasons, official sources may be slower to access domestically.
