How do you solve the problem that the number of noising queries can't be same in a batch #8

The number of Ground Truth is different in different images, so the number of noising queries can't be same for the images in a same batch, how do you solve this problem?

There are 2 ways to solve this problem. In DN-DETR, we pad the noising queries in a batch to the same length. In DINO, we further propose a more efficient method named dynamic denoising groups, you can refer to DINO for more details. Thank you.
