24.11.2019 · The loss you're looking at is designed for situations where each example can belong to multiple classes (say a person can be classified as both female and old). I think it's this "multi" that confuses you - it stands for the multiple possible classifications per example , not just multiple potential labels in the whole "universe".

https://pytorch.org/docs/stable/generated/torch.nn.MultiLabelMarginLoss.html
MultiLabelMarginLoss class torch.nn.MultiLabelMarginLoss(size_average=None, reduce=None, reduction='mean') [source] Creates a criterion that optimizes a multi-class multi-classification hinge loss (margin-based loss) between input x x (a 2D mini-batch Tensor ) and output y y (which is a 2D Tensor of target class indices).
