- For training, we train YOLOv5 series with 300 epochs on COCO.
- For data augmentation, we use the large scale jitter (LSJ), Mosaic augmentation and Mixup augmentation, following the setting of YOLOv5.
- For optimizer, we use AdamW with weight decay 0.05 and base per image lr 0.001 / 64. We are not good at using SGD.
- For learning rate scheduler, we use linear decay scheduler.
- We use decoupled head in our reproduced YOLOv5, which is different from the official YOLOv5'head.
Train YOLOv5
Single GPU
Taking training YOLOv5-S on COCO as the example,
python train.py --cuda -d coco --root path/to/coco -m yolov5_s -bs 16 -size 640 --wp_epoch 3 --max_epoch 300 --eval_epoch 10 --no_aug_epoch 20 --ema --fp16 --multi_scale
Multi GPU
Taking training YOLOv5 on COCO as the example,
python -m torch.distributed.run --nproc_per_node=8 train.py --cuda -dist -d coco --root /data/datasets/ -m yolov5_s -bs 128 -size 640 --wp_epoch 3 --max_epoch 300 --eval_epoch 10 --no_aug_epoch 20 --ema --fp16 --sybn --multi_scale --save_folder weights/
Test YOLOv5
Taking testing YOLOv5 on COCO-val as the example,
python test.py --cuda -d coco --root path/to/coco -m yolov5_s --weight path/to/yolov5_coco.pth -size 640 --show
Evaluate YOLOv5
Taking evaluating YOLOv5 on COCO-val as the example,
python eval.py --cuda -d coco --root path/to/coco -m yolov5_s --weight path/to/yolov5_coco.pth
