|
|
Usage examples for running YOLOv8:
|
|
|
|
1. Install the ultralytics package:
|
|
|
|
pip install ultralytics
|
|
|
|
2. Use the Python SDK:
|
|
|
|
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
|
|
results = model.train(data="coco128.yaml", epochs=3) # train the model
|
|
results = 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
|
|
|
|
3. Use the command line interface (CLI):
|
|
|
|
YOLOv8 'yolo' CLI commands use the following syntax:
|
|
|
|
yolo TASK MODE ARGS
|
|
|
|
Where TASK (optional) is one of [detect, segment, classify]
|
|
MODE (required) is one of [train, val, predict, export]
|
|
ARGS (optional) are any number of custom 'arg=value' pairs like 'imgsz=320' that override defaults.
|
|
See all ARGS at https://docs.ultralytics.com/usage/cfg or with 'yolo cfg'
|
|
|
|
- Train a detection model for 10 epochs with an initial learning_rate of 0.01
|
|
yolo detect train data=coco128.yaml model=yolov8n.pt epochs=10 lr0=0.01
|
|
|
|
- Predict a YouTube video using a pretrained segmentation model at image size 320:
|
|
yolo segment predict model=yolov8n-seg.pt source='https://youtu.be/Zgi9g1ksQHc' imgsz=320
|
|
|
|
- Val a pretrained detection model at batch-size 1 and image size 640:
|
|
yolo detect val model=yolov8n.pt data=coco128.yaml batch=1 imgsz=640
|
|
|
|
- Export a YOLOv8n classification model to ONNX format at image size 224 by 128 (no TASK required)
|
|
yolo export model=yolov8n-cls.pt format=onnx imgsz=224,128
|
|
|
|
- Run special commands:
|
|
yolo help
|
|
yolo checks
|
|
yolo version
|
|
yolo settings
|
|
yolo copy-cfg
|
