Question
Is it possible to use supervision in a headless environment? If so, what is the recommended approach? This would require using opencv-python-headless instead of opencv-python in the dependencies.
Additional
#130 is related, but not a solution. opencv-python-headless and opencv-python are mutually exclusive dependencies - installing both breaks the environment.
I can see that in the past Supervision used to require headless and then moved to the gui-enabled version for wider ecosystem compatibility. I agree with that decision, but it puts users who want to use Supervion in a headless environment in a tricky situation.
For the ultraltyics package (which has the same problem) third parties have created a separate repository that modifies the dependency and distributes an alternative package - see https://github.com/Teriks/dgenerate-ultralytics-headless by @Teriks . I like this approach, but it does require manually ensuring that both opencv-python-headless and opencv-python do not end up installed in the same environment e.g. via transitive dependencies.
Ultimately, I feel the source of this challenge is opencv's legacy packaging choices, but that's not practically solvable for various reasons. If the communitiy could consistency approach it with the same solutions, then that would mitigate a lot of the downstream consequences for headless users.
