### CLI
YOLO 可以直接在命令行接口(CLI)中使用 `yolo` 命令:
```bash
yolo predict model=yolo11n.pt source='https://ultralytics.com/images/bus.jpg'
```
`yolo` 可以用于各种任务和模式,并接受额外参数,例如 `imgsz=640` 。请参阅 YOLO [CLI 文档 ](https://docs.ultralytics.com/usage/cli/ ) 以获取示例。
### Python
YOLO 也可以直接在 Python 环境中使用,并接受与上述 CLI 示例中相同的[参数](https://docs.ultralytics.com/usage/cfg/):
```python
from ultralytics import YOLO
# 加载模型
model = YOLO("yolo11n.pt")
# 训练模型
train_results = model.train(
data="coco8.yaml", # 数据集 YAML 路径
epochs=100, # 训练轮次
imgsz=640, # 训练图像尺寸
device="cpu", # 运行设备,例如 device=0 或 device=0,1,2,3 或 device=cpu
)
# 评估模型在验证集上的性能
metrics = model.val()
# 在图像上执行对象检测
results = model("path/to/image.jpg")
results[0].show()
# 将模型导出为 ONNX 格式
path = model.export(format="onnx") # 返回导出模型的路径
```
