# Train COCO Dataset

This guidence shows the training commands for reproducing our results on COCO Dataset.

## For P5 models

#### YOLOv6-N

```shell
# Step 1: Training a base model
# Be sure to open use_dfl mode in config file (use_dfl=True, reg_max=16)

python -m torch.distributed.launch --nproc_per_node 8 tools/train.py \
									--batch 128 \
									--conf configs/yolov6n.py \
									--data data/coco.yaml \
									--epoch 300 \
									--fuse_ab \
									--device 0,1,2,3,4,5,6,7 \
									--name yolov6n_coco

# Step 2: Self-distillation training
python -m torch.distributed.launch --nproc_per_node 8 tools/train.py \
									--batch 128 \
									--conf configs/yolov6n.py \
									--data data/coco.yaml \
									--epoch 300 \
									--device 0,1,2,3,4,5,6,7 \
									--distill \
									--teacher_model_path runs/train/yolov6n_coco/weights/best_ckpt.pt \
									--name yolov6n_coco
```


#### YOLOv6-S/M/L

```shell
# Step 1: Training a base model
# Be sure to open use_dfl mode in config file (use_dfl=True, reg_max=16)

python -m torch.distributed.launch --nproc_per_node 8 tools/train.py \
									--batch 256 \
									--conf configs/yolov6s.py \ # yolov6m/yolov6l
									--data data/coco.yaml \
									--epoch 300 \
									--fuse_ab \
									--device 0,1,2,3,4,5,6,7 \
									--name yolov6s_coco # yolov6m_coco/yolov6l_coco

# Step 2: Self-distillation training
python -m torch.distributed.launch --nproc_per_node 8 tools/train.py \
									--batch 256 \ # 128 for distillation of yolov6l
									--conf configs/yolov6s.py \ # yolov6m/yolov6l
									--data data/coco.yaml \
									--epoch 300 \
									--device 0,1,2,3,4,5,6,7 \
									--distill \
									--teacher_model_path runs/train/yolov6s_coco/weights/best_ckpt.pt \
									--name yolov6s_coco # yolov6m_coco/yolov6l_coco

```
