Hey @Richard83832
We have a forum topic for that video exploring it, but the fix is to instead use this line here:
pip install ultralytics==8.3.100
Recent Ultralytics updates to the package have broken it, and until its fixed it will keep giving the “Dependency resolution exceeded maximum depth” error. This line installs a version from a few months ago but should work fine with what’s explored in the video.
Let us know how it goes!
