Hi,
I see that starting from deformable DETR, it doesn't make sense to have cardinality loss. In the original DETR paper, the class_embed head outputs num_classes + 1, to also output a value for th…

B导，你这个能将loss_obj替换为Focal Loss么，为什么我尝试替换后loss_obj在训练过程中一直为0啊？
-
Did you try Focal loss, how about its performance ?

I try to merge your focal-loss with SSD, the training loss can converge to 1.x, but the testset mAP is not as well as OHEM method. Have you test focal-loss on any dataset?

我在tiny的版本上开启focal loss的训练，并设置50个epoch后才开始测试，此时仍然会出现因为nms导致的显存爆炸

Hi @unsky
Please, can you check, did I read your Focal Loss formulas correctly?
For CE, delta is:
* `if (i == j)` then `delta = 1-p`
* `if (i != j)` then `delta = -p`

For Focal Los…

## 🚀 Feature
Currently we only support focal loss for binary cases.
Some users have reported the need to use it for multi class classification #551
