WebBCELoss — PyTorch 1.13 documentation BCELoss class torch.nn.BCELoss(weight=None, size_average=None, reduce=None, reduction='mean') [source] Creates a criterion that measures the Binary Cross Entropy between the target and the input probabilities: The unreduced (i.e. with reduction set to 'none') loss can be … Could be an overflow or underflow error. This will make any loss function give you a tensor(nan).What you can do is put a check for when loss is nan and let the weights adjust themselves. criterion = SomeLossFunc() eps = 1e-6 loss = criterion(preds,targets) if loss.isnan(): loss=eps else: loss = loss.item() loss = loss+ L1_loss + ...
