YOLOv7-AF-T 1xb16 640 80.6 ckpt log
  • For training, we train redesigned YOLOv7-AF with 500 epochs on COCO. We also use the gradient accumulation.
  • For data augmentation, we use the RandomAffine, RandomHSV, Mosaic and YOLOX's Mixup augmentation.
  • For optimizer, we use AdamW with weight decay of 0.05 and per image base lr of 0.001 / 64.
  • For learning rate scheduler, we use cosine decay scheduler.
  • For batch size, we set it to 16, and we also use the gradient accumulation to approximate batch size of 256.

Train YOLOv7-AF

Single GPU

Taking training YOLOv7-AF-S on COCO as the example,

python train.py --cuda -d coco --root path/to/coco -m yolov7_af_s -bs 16 --fp16 

Multi GPU

Taking training YOLOv7-AF-S on COCO as the example,

python -m torch.distributed.run --nproc_per_node=8 train.py --cuda --distributed -d coco --root path/to/coco -m yolov7_af_s -bs 16 --fp16 

Test YOLOv7-AF

Taking testing YOLOv7-AF-S on COCO-val as the example,

python test.py --cuda -d coco --root path/to/coco -m yolov7_af_s --weight path/to/yolov7.pth --show 

Evaluate YOLOv7-AF

Taking evaluating YOLOv7-AF-S on COCO-val as the example,
