Hi Xingyi,

Thanks for your work. Does 'gt_3d = gt_3d - gt_3d[:1]' in L133 mean to subtract the root joint position?

pytorch-pose-hg-3d/src/lib/datasets/h36m_iccv.py

Lines 130 to 138 in 373f4b7

	def _get_part_info(self, index):
	ann = self.annot[self.idxs[index]]
	gt_3d = np.array(ann['gt_3d'], dtype=np.float32)
	gt_3d = gt_3d - gt_3d[:1]
	gt_3d = gt_3d[self.h36m_to_mpii]
	pts = np.array(ann['uvd'], dtype=np.float32)
	c = np.array([112, 112], dtype=np.float32)
	s = 224.
	return gt_3d, pts, c, s
