When I run python projects/SGT/train_net.py --config-file projects/SGT/configs/MOT17/sgt_dla34.yaml --data-dir /data/liuqigui/project/dataset --num-gpus 1 OUTPUT_DIR /data/liuqigui/project/SGT-main/sgt_output/mot17_train/dla34_mot17-CH2， this problem happened.

I don't know why this problem occurred. The dataset was also downloaded from yours. The CrowdHuman dataset also has this problem.

Hi. Sorry for the late reply. This logging output is not the error. When the visibility threshold of 0.0 is used, it means that all images should be used. Thus, none of the images is removed and all images are left as shown in the logging output.
