```python
tensorplay.nn.functional.multi_margin_loss(input: Tensor, target: Tensor, p: int = 1, margin: float = 1.0, weight: Tensor | None = None, size_average=None, reduce=None, reduction: str = 'mean') → Tensor
```

Compute the multi margin loss, with optional weighting.

sum_d max(0, margin - x_y + x_d)^p * w_y / C over non-target classes.
See MultiMarginLoss for details.
