- For training, we train redesigned YOLOv3 with 150 epochs on COCO. We also gradient accumulate.
- For data augmentation, we only use the large scale jitter (LSJ), no Mosaic or Mixup augmentation.
- For optimizer, we use SGD with momentum 0.937, weight decay 0.0005 and base lr 0.01.
- For learning rate scheduler, we use linear decay scheduler.
Train YOLOv3
Single GPU
Taking training YOLOv3 on COCO as the example,
python train.py --cuda -d coco --root path/to/coco -m yolov3 -bs 16 -size 640 --wp_epoch 3 --max_epoch 150 --eval_epoch 10 --no_aug_epoch 10 --ema --fp16 --multi_scale
Multi GPU
Taking training YOLOv3 on COCO as the example,
python -m torch.distributed.run --nproc_per_node=8 train.py --cuda -dist -d coco --root /data/datasets/ -m yolov3 -bs 128 -size 640 --wp_epoch 3 --max_epoch 150 --eval_epoch 10 --no_aug_epoch 20 --ema --fp16 --sybn --multi_scale --save_folder weights/
Test YOLOv3
Taking testing YOLOv3 on COCO-val as the example,
python test.py --cuda -d coco --root path/to/coco -m yolov3 --weight path/to/yolov3.pth -size 640 -vt 0.3 --show
Evaluate YOLOv3
Taking evaluating YOLOv3 on COCO-val as the example,
python eval.py --cuda -d coco-val --root path/to/coco -m yolov3 --weight path/to/yolov3.pth
