Hi, yukang @yukang2017, yanwei @yanwei-li,
I am confused about the iou related loss you used in dense head(IoULossSparse and IoURegLossSparse). I reproduce your model on my devices, but I find IoURegLossSparse does not seem to going down, it keeps almost the same value in the training process. I use IoURegLoss in another model, I trap into the same problem(not decrease). Could you please show me your intention to use the loss?

Additionally, why use IoULossSparse and IoURegLossSparse repsectively? I can't understand the purpose of their use. Looking forward to your reply, thank you.

Best regards.
