输入GCN的tensor要求的人数是2个，但大多数的NTU动作是单人的，因此是需要把第一个人的keypoint信息复制到tensor中的第二个人的位置上。但此处的代码: pyskl/datasets/pipelines/pose_related.py:

第450行， 此处已经将单人的keypoint tensor和zero tensor进行了concatenate操作，得到的tensor已经是代表两个人的了。那下一行的判断条件里的keypoint.shape[0] 就不可能等于1，这还怎么执行随后的复制操作？

还是说单人的动作，只需要给第二个人的位置填充zero tensor，不需要复制第一个人的信息？
