Difference between ECCV paper and YouTube-VIS challenge

[DUT-CSJ]

Hello, thank you for release your great work.
I want to know training difference between ECCV paper and YouTube-VIS challenge.
The mAP_L in your YouTube-VIS challenge paper is much higher than the checkpoint in this repo (50.7 vs 44.6).
I try to use training settings in YouTube-VIS challenge paper to train IDOL (iter:12000, step:6000, lr:0.0002) while the result is even worse than the checkpoint in this repo.
So I wonder why the mAP_L in your YouTube-VIS challenge paper is so high?
Looking forward to your reply, thank you very much!
Best.

Except iter, step and lr, I use default settings for other. I also use 8*A100 to train.
