When using the v8 version for training, I added the pre-training weight file of yolov8l.pt to mot17_train_cfg.py and encountered a problem.

[luke110]

I rewrote the build trainer in mot17_train_config.py

Like this:

train = dict( output_dir="./yolov8_mot17_train-all", init_checkpoint="/HOME/scw6492/run/luke/yolov8/pretrain/yolov8l.pt",

I only change this.

Next I encountered the following problem： [01/19 14:05:56 d2.checkpoint.detection_checkpoint]: [DetectionCheckpointer] Loading from /HOME/scw6492/run/luke/yolov8/pretrain/yolov8l.pt ...
