Target format for MultiLabelMarginLoss

1

I am using MultiLabelMarginLoss loss function. The target values to the loss function are the indices followed by -1.
For example, if the correct label indices are 3 and 4, the target tensor looks something like this -

target = torch.tensor([3, 4, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1]).to(device)

Is this the correct format for the target?

This is the correct tensor format for MultiLabelMarginLoss.
