Implementation about the stuff and thing queries

[peiwang062]

Hello authors, thanks for the great work!

I just have a quick question about the code. One of the main contribution of the paper is to use the foreground query and background query. But in the given script of COCO panoptic evaluation, I saw that only the 300 foreground queries were used. There is no 100 stuff class queries mentioned in the paper. I indeed saw the variable num_queries_stuff in openseed_decoder_decouple.py, but it is not used in the implementation. Isn't the released code the fully implementation of the paper, am I missing something?
