### 训练
|
|
|
|
|
|
YOLOv5分割训练支持自动下载 COCO128-seg 分割数据集，用户仅需在启动指令中包含 `--data coco128-seg.yaml` 参数。 若要手动下载，使用命令 `bash data/scripts/get_coco.sh --train --val --segments`， 在下载完毕后，使用命令 `python train.py --data coco.yaml` 开启训练。
|
|
|
|
|
|
```bash
|
|
|
# 单 GPU
|
|
|
python segment/train.py --data coco128-seg.yaml --weights yolov5s-seg.pt --img 640
|
|
|
|
|
|
# 多 GPU， DDP 模式
|
|
|
python -m torch.distributed.run --nproc_per_node 4 --master_port 1 segment/train.py --data coco128-seg.yaml --weights yolov5s-seg.pt --img 640 --device 0,1,2,3
|
|
|
```
|
|
|
|
|
|
### 验证
|
|
|
|
|
|
在 COCO 数据集上验证 YOLOv5s-seg mask mAP：
|
|
|
|
|
|
```bash
|
|
|
bash data/scripts/get_coco.sh --val --segments # 下载 COCO val segments 数据集 (780MB, 5000 images)
|
|
|
python segment/val.py --weights yolov5s-seg.pt --data coco.yaml --img 640 # 验证
|
|
|
```
|
|
|
|
|
|
### 预测
|
|
|
|
|
|
使用预训练的 YOLOv5m-seg.pt 来预测 bus.jpg：
|
|
|
|
|
|
```bash
|
|
|
python segment/predict.py --weights yolov5m-seg.pt --source data/images/bus.jpg
|
|
|
```
|
|
|
|
|
|
```python
|
|
|
model = torch.hub.load(
|
|
|
"ultralytics/yolov5", "custom", "yolov5m-seg.pt"
|
|
|
) # 从load from PyTorch Hub 加载模型 (WARNING: 推理暂未支持)
|
|
|
```
|
|
|
|
|
|
|  |  |
|
|
|
| ---------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
|
|
|
|
|
|
### 模型导出
|
|
|
|
|
|
将 YOLOv5s-seg 模型导出到 ONNX 和 TensorRT：
|
|
|
|
|
|
```bash
|
|
|
python export.py --weights yolov5s-seg.pt --include onnx engine --img 640 --device 0
|
|
