[Ultralytics YOLOv8](https://github.com/ultralytics/ultralytics), developed by [Ultralytics](https://ultralytics.com),
|
|
is a cutting-edge, state-of-the-art (SOTA) model that builds upon the success of previous YOLO versions and introduces
|
|
new features and improvements to further boost performance and flexibility. YOLOv8 is designed to be fast, accurate, and
|
|
easy to use, making it an excellent choice for a wide range of object detection, image segmentation and image
|
|
classification tasks.

<summary>Install</summary>
|
|
|
|
Pip install the ultralytics package including
|
|
all [requirements](https://github.com/ultralytics/ultralytics/blob/main/requirements.txt) in a
|
|
[**Python>=3.7**](https://www.python.org/) environment with
|
|
[**PyTorch>=1.7**](https://pytorch.org/get-started/locally/).
|
|
|
|
```bash
|
|
pip install ultralytics
|
|
```

<summary>Usage</summary>
|
|
|
|
#### CLI
|
|
|
|
YOLOv8 may be used directly in the Command Line Interface (CLI) with a `yolo` command:
|
|
|
|
```bash
|
|
yolo predict model=yolov8n.pt source='https://ultralytics.com/images/bus.jpg'
|
|
```
|
|
|
|
`yolo` can be used for a variety of tasks and modes and accepts additional arguments, i.e. `imgsz=640`. See the YOLOv8
|
|
[CLI Docs](https://docs.ultralytics.com/usage/cli) for examples.
|
|
|
|
#### Python
|
|
|
|
YOLOv8 may also be used directly in a Python environment, and accepts the
|
|
same [arguments](https://docs.ultralytics.com/usage/cfg/) as in the CLI example above:
|
|
|
|
```python
|
|
from ultralytics import YOLO
|
|
|
|
# Load a model
|
|
model = YOLO("yolov8n.yaml") # build a new model from scratch
|
|
model = YOLO("yolov8n.pt") # load a pretrained model (recommended for training)
|
|
|
|
# Use the model
|
|
model.train(data="coco128.yaml", epochs=3) # train the model
|
|
metrics = model.val() # evaluate model performance on the validation set
|
|
results = model("https://ultralytics.com/images/bus.jpg") # predict on an image
|
|
success = model.export(format="onnx") # export the model to ONNX format
|
|
```
