使用基于论文Hourglass 的模型实现人体关键点检测。


containing:
- boxes (Tensor[N, 4]): the ground-truth boxes in[x0, y0, x1, y1]format, with values
between0andHand0andW
- labels (Tensor[N]): the class label for each ground-truth box
- keypoints (Tensor[N, K, 3]): theKkeypoints location for each of theNinstances, in the
format[x, y, visibility], wherevisibility=0means that the keypoint is not visible.The model returns a
