ConvertKeypoints()交换关键点顺序，剩下其他代码并未交换顺序
def _convert(self, keypoints, w, h):

converted_keypoints = list(keypoints[i - 1] for i in reorder_map)
converted_keypoints.insert(1, [(keypoints[5][0] + keypoints[6][0]) / 2,
(keypoints[5][1] + keypoints[6][1]) / 2, 0]) # Add neck as a mean of shoulders
if keypoints[5][2] == 2 or keypoints[6][2] == 2:

elif keypoints[5][2] == 1 and keypoints[6][2] == 1:
converted_keypoints[1][2] = 1

or converted_keypoints[1][0] >= w
