RuntimeError: selected index k out of range， topK out of range when doing evalutaion

Hi, really appreciate your brilliant work.

I am trying to use DINO to train my own dataset with 2 classes. I modified num_classes=3 and dn_labelbook_size = 3 (I think it is necessary), then start training. After one epoch, I get this error when doing evaluation.

Any advice？

Thanks.

Two more question:

Have you ever had experiments for DINO under different number of queries?

When training with customer dataset, except num_classes and dn_labelbook_size, are there any variables related to the number of classes need to be change?

Q1: Reducing 900 queries to 300 queries will slightly reduce the performance (about 0.5 AP). Q2: No other hyper-parameter to change.
