Hello dear Pytorch-User,
i have the following question:
suppose you have a very simple network with:
input  * w1 = output
MSE(output,target) = loss
Then you need the value from input for the backpropagation. But i can t find the place where it is saved. I allready read a little bit about the backpropagation system from pytorch, but it didnt give me the answer to this question. I am just curious, its not very important.
