visualize hand skeleton

[qwer904]

Hello, I want to visualize the hand skeleton in the output picture, how should I do it? Are you using your vis_keypoints(img, kps, kps_gt, bbox, score, skeleton, filename, score_thr=0.4, line_width=3, circle_rad = 3, save_path=None) function? If so, how should the parameters img, kps, kps_gt, bbox, score, and skeleton be set?
