Question

while running yolo-nas and sam for segmentation of my sample video i am getting error as
ERROR:
detections = detections[detections.area == np.max(detections.area)]
---> 62 segmented_mask = mask_annotator.annotate(scene=frame, detections=detections)
63 return segmented_mask

/usr/local/lib/python3.10/dist-packages/supervision/annotators/core.py in annotate(self, scene, detections, custom_color_lookup)
250 )
251 mask = detections.mask[detection_idx]
--> 252 colored_mask[mask] = color.as_bgr()
253
254 scene = cv2.addWeighted(colored_mask, self.opacity, scene, 1 - self.opacity, 0)

Hi @josh-001 👋🏻 ! It does not look like a bug related to supervision. Looks more like something related to SAM result processing. Wile reading your code I noticed, they you do not use sv.Detections.from_sam(sam_result=sam_result). Here is a colab where we show how to combo SAM and Supervision.

I'll also convert this issue into a discussion and put it in the Q&A section.
