```

### Multi GPU
Taking training **YOLOF_R18_C5_1x** on COCO as the example,
```Shell
python -m torch.distributed.run --nproc_per_node=8 train.py --cuda -dist -d coco --root path/to/coco -m yolof_r18_c5_1x --batch_size 16 --eval_epoch 2 
```

## Test YOLOF
Taking testing **YOLOF_R18_C5_1x** on COCO-val as the example,
```Shell
python test.py --cuda -d coco --root path/to/coco -m yolof_r18_c5_1x --weight path/to/yolof_r18_c5_1x.pth -vt 0.4 --show 
```

## Evaluate YOLOF
Taking evaluating **YOLOF_R18_C5_1x** on COCO-val as the example,
