Quickstart
Installation
Install YOLOv8 via the ultralytics
pip package for the latest stable release or by cloning the https://github.com/ultralytics/ultralytics repository for the most up-to-date version.
git clone

The command line YOLO interface lets you simply train, validate or infer models on various tasks and versions.
CLI requires no customization or code. You can simply run all tasks from the terminal with the yolo
command.
Note
Python API
The Python API allows users to easily use YOLOv8 in their Python projects. It provides functions for loading and running the model, as well as for processing the model's output. The interface is designed to be easy to use, so that users can quickly implement object detection in their projects.
Overall, the Python interface is a useful tool for anyone looking to incorporate object detection, segmentation or classification into their Python projects using YOLOv8.
Note
from ultralytics import YOLO
model = YOLO('yolov8n.yaml') # build a new model from scratch
model = YOLO('yolov8n.pt') # load a pretrained model (recommended for best training results)
results = model.train(data='coco128.yaml') # train the model
results = model.val() # evaluate model performance on the validation set
results = model.predict(source='bus.jpg') # predict on an image
success = model.export(format='onnx') # export the model to ONNX format
