WebYou’ll also need to set Keypoint OKS with TEST.KEYPOINT_OKS_SIGMAS for evaluation. MODEL.SEM_SEG_HEAD.NUM_CLASSES sets the number of stuff classes for Semantic FPN & Panoptic FPN. TEST.DETECTIONS_PER_IMAGE controls the maximum number of objects to be detected. Set it to a larger number if test images may contain >100 objects. Web14 jul. 2024 · Some keys are superfluous such as "keypoint colors". However in my experience with detectron2 superfluous keys are ignored and do not pose a problem. The actual error message you are getting is due to the fact that you have annotations that have category_id that detectron's mapping does not account for.
