I fllow the insturction in this page in my code.
However I got this error.
Traceback (most recent call last):

TypeError: add() received an invalid combination of arguments - got (tuple), but expected one of:

• (Tensor other, float alpha)
• (float other, float alpha)

the outputs is a list,each item is a small tensor(each tensor is on different gpu), labels is not a list, but a tensor on gpu:0
