Pip install dlib is taking 3 hours and yet not completed.
Stuck at "Running setup.py bdist_wheel for dlib ... "
How long will it take?
I'm using Raspberry pi B+

[@SPARKLERSWeAreTheMakers]

3 hours is too much I think, but still you should wait until it completes.

[@speedy_petey]

I had the same problem with the bookworm version when installed using the pi imager. I fixed it earlier by installing the Bullseye OS. Hope this helps.
