hi ptrblck.I am big fan of your support to this community.I am trying to generate a depth map for a given image.So i used BCELoss() for this where  output(to loss function by model) is of size  [10,1,250,250] and target(to loss function ground depth) is [10,1,250,250].
Now i am thinking of  using reduction="mean’ and  backpropagate it.But it is giving me huge values as loss.Plz let me know your opinion.plz tell me which loss function is better in this scenario
