The weight of match_loss in QueryTrack.

Dear author：
The weight of box_head loss is 2，5，2 ，and mask_head loss is 8 in QueryInst. Can you tell me the weight of box_head，mask_head，track_head in QueryTrack？ Sincere thanks ^-^

Hi @kay-Lifeng, thanks for your interest in our work.

We simply set the weight of track_head to 1 and keep other loss weights unchanged.

At least in our large QueryTrack model (w/ Swin-L backbone), we found the performance is insensitive to the weight of track_head, but the performance of all QueryInst models are sensitive to the weight of mask_head.

I'm closing this issue but let us know if you have any further questions.
