Where is definition of `LocalizationDistillationLoss`?

[songtianhui]

For something like self.loss_ld = build_loss(dict(type='LocalizationDistillationLoss'...)) I seem not to find the class definition of it in this codebase...

It has no problem. But for example here https://github.com/HikariTJU/LD/blob/2dda5c043e733c7cc40f6ce41fb37d0e76c44eeb/mmdet/models/dense_heads/ld_fcos_head.py#L33, where is this loss implementation?
