安装

```shell
pip install ultralytics
```

使用预训练的模型（会自动下载）

> 预训练模型分为[10档](https://github.com/ultralytics/yolov5#pretrained-checkpoints)
>

```python
from ultralytics import YOLO

model = YOLO("yolov8n.pt")
```

预测

```python
inputs = [img, img] # list of np arrays
results = model(inputs) # List of Results objects
for result in results:
    boxes = result.boxes # Boxes object for bbox outputs
    masks = result.masks # Masks object for segmenation masks outputs
    probs = result.probs # Class probabilities for classification outputs
    ...
```
