Documentation

See below for a quickstart install and usage examples, and see our Docs for full documentation on training, validation, prediction and deployment.

Install

Pip install the ultralytics package including all requirements in a Python>=3.8 environment with PyTorch>=1.8.

pip install ultralytics

For alternative installation methods including Conda, Docker, and Git, please refer to the Quickstart Guide.

Usage

CLI

Ultralytics YOLO may be used directly in the Command Line Interface (CLI) with a yolo command:

yolo predict model=yolo26n.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 Ultralytics YOLO CLI Docs for examples.

Python

Ultralytics YOLO may also be used directly in a Python environment, and accepts the same arguments as in the CLI example above:

from ultralytics import YOLO
# Load a model
model = YOLO("yolo26n.pt")
# Train the model
train_results = model.train(
    data="coco8.yaml",  # path to dataset YAML
    epochs=100,  # number of training epochs
    imgsz=640,  # training image size
    device="cpu",  # device to run on, i.e. device=0 or device=0,1,2,3 or device=cpu
)
# Evaluate model performance on the validation set
metrics = model.val()
# Perform object detection on an image
results = model("path/to/image.jpg")
results[0].show()
# Export the model to ONNX format
path = model.export(format="onnx")  # return path to exported model

See Ultralytics YOLO Python Docs for more examples.

Models

Ultralytics YOLO26 Detect, Segment and Pose models pretrained on the COCO dataset are available here, as well as Ultralytics YOLO26 Classify models pretrained on the ImageNet dataset. Track mode is available for all Detect, Segment and Pose models.
