Are these losses normal when I train in coco

The focal loss is much bigger than other losses, when I train in coco, the total loss can't converge. Who know why?

I have the same question, could @Duankaiwen explain if it is normal?

[Duankaiwen]

Hi, the losses are normal. These losses converge slowly. BTW, what's your batch size? @ xuyongxi @fuqichen1998

[fuqichen1998]

Thanks! My batch size is 16 for CenterNet-52.

@fuqichen1998 I have set batch size 16 for CenterNet52. And the learning rate is changed into 2.5e-5 in 1000 epoch. (Using the CenterNet-480000 for pretianed model). Have you achieve the author's result?
