ImportError: cannot import name 'box_iou_batch' from 'supervision.detection.utils'

[SlawekTT]

When importing trackers, the following error occurs:

ImportError: cannot import name 'box_iou_batch' from 'supervision.detection.utils'

This happens because box_iou_batch was recently moved in supervision package (>=0.26) to "supervision.detection.utils.iou_and_nms", while trackers still tries to import it from the old location supervision.detection.utils.

Possible fixes: Update import paths in trackers or pin supervision<0.26 in trackers dependencies.
