Can I ask why this is beneficial over previous custom models?

Can I ask why this is beneficial over previous custom models?

I'm not sure if this is the exact answer to your question, but the original torchvision model was implemented to support only multi-class classification, so this PR simply extends it to allow multi-label and h-label to be used as well. It's a simple extension of the functionality.
