KeyError: 'Non-existent config key: SGT'

[liuqigui]

Hello, when I execute python projects/SGT/train_net.py --config-file projects/SGT/configs/MOT17/sgt_dla34.yaml --data-dir /root/datasets --num-gpus 1 -- eval-only OUTPUT_DIR /root/sgt_output/mot17_test/dla34_mot17-CH command, I encountered KeyError: 'Non-existent config key: SGT'. What should I do to fix it?
thank you!
