Hi all, Thank you for bringing up the issue and sorry for the very delayed response. It is caused by incorrect size divisibility in the fcos_bifpn backbone. I have fixed this in the most recent commit and the error should have gone. Strangely I didn't meet this before when I train the model. This may indicate there are some unnoted differences between the release code and my development version. I will check this.

When I train CenterNet2_DLA-BiFPN-P3_24x.yaml, I have a problem.

File "/data/anaconda3/envs/detectron2/lib/python3.8/site-packages/yacs/config.py", line 491, in _merge_a_into_b raise KeyError("Non-existent config key: {}".format(full_key)) KeyError: 'Non-existent config key: MODEL.ROI_BOX_HEAD.MULT_PROPOSAL_SCORE'

@XYSC @xingyizhou I also facing the same problem.

You can use this below code to add new config keys: from detectron2.projects.CenterNet2.centernet.config import add_centernet_config cfg = get_cfg() add_centernet_config(cfg)
