Hi, I'm trying to adapt the MOTR codebase to our own datasets (and thanks for releasing the great work)!

I have a question regarding the comment in https://github.com/megvii-research/MOTR/blob/8690da3392159635ca37c31975126acf40220724/models/qim.py#L138

This comment says set -2 instead of -1 to ensure that these tracks will not be selected in matching., but it seems that the code doesn't set the label to -2 anywhere below. Could it be a bug, or am I missing something?

Thank you!
