It looks like you need to run with --no-build-isolation.

[charliermarsh]

(detectron2 doesn't declare torch as a build-time dependency, so you're responsible for installing it ahead-of-time and then disabling build dependencies entirely.)

Thank you! The project is amazing - I do hope we will get rust like experience in python - that would be awesome. The --no-build-isolation flag works!

It looks like it is an issue with detectron2 as mentioned in #2252 - closing.
