How to create empty Detections object?

How to deal with the situation when nothing is detected? Currently, there is no possibility to create a Detections object with empty arrays.

Hi, @adrianboguszewski 👋🏻! Sorry for the late reply. I was on a short vacation. Currently, it is only possible to create empty detection like this:

Detections(
    xyxy=np.empty((0, 4), dtype=np.float32),
    confidence=np.array([], dtype=np.float32),
    class_id=np.array([], dtype=int)
)

Would you be satisfied with some code sugar like this: Detection.empty() that would essentially do the same?

Thanks for the answer. It wasn't so late :)

Yeah, I think Detections.empty() (or similar) is worth considering.

Okay I think you are right. I’ll keep you posted.
