Don't do any of that other stuff, just do pip install dlib. That should work without issue.

[ITApeDeHao]

do pip install dlib .I can't use GPU to speed up computing

[MrWhite928]

I have encountered a similar problem, but the difference is that my Python version is 3.8. Do you know how to solve it?

[ITApeDeHao]

我遇到过类似的问题，但不同的是，我的Python版本是3.8。你知道怎么解决它吗？

Sorry, I have not used other versions for testing, and I only successfully compiled on one computer. After I changed the computer, this error still occurred when I used the above version. I think it may be caused by some execution error of my step.
