Instructions To Reproduce the 🐛 Bug:

1. what changes you made (git diff) or what code you wrote

Nothing change

2. what exact command you run: python -m torch.distributed.launch --nproc_per_node=8 --use_env main.py --coco_path ../data/COCO2017 --output_dir output/conddetr_r50_epoch50
3. what you observed (including full logs):

Sorry but we never encountered this error. It indicates that the predicted boxes have a negative width or height. Which should not happen. The predicted (cx, cy, h, w) are fed into a sigmoid, so all h, w should be in range [0, 1].
