Hi thanks for your code! I got an error as the title when call loss.backward, I fixed it when I changed self.save_for_backward(tenIn, tenFlow) into self.save_for_backward(tenIn.clone(), tenFlow.clone()), I don't know if it is right?

What is the layer before and the layer after the softmax splatting in your network?
