YOLOv8: State-of-the-Art Computer Vision Model

What is YOLOv8?

YOLOv8 is a computer vision model architecture developed by Ultralytics, the creators of YOLOv5. You can deploy YOLOv8 models on a wide range of devices, including NVIDIA Jetson, NVIDIA GPUs, and macOS systems with Roboflow Inference, an open source Python package for running vision models.

Deploy a YOLOv8 Model

To deploy a YOLOv8 model, first install Inference with pip install inference. Then:

 from inference import get_model
import supervision as sv
from inference.core.utils.image_utils import load_image_bgr
 
image = load_image_bgr("https://media.roboflow.com/inference/vehicles.png")
model = get_model(model_id="yolov8n-640")
results = model.infer(image)[0]
results = sv.Detections.from_inference(results)
annotator = sv.BoxAnnotator(thickness=4)
annotated_image = annotator.annotate(image, results)
annotator = sv.LabelAnnotator(text_scale=2, text_thickness=2)
annotated_image = annotator.annotate(annotated_image, results)
sv.plot_image(annotated_image)

 from inference import InferencePipeline
from inference.core.interfaces.stream.sinks import render_boxes
 
pipeline = InferencePipeline.init(
    model_id="yolov8n-640",
    video_reference=0,
    on_prediction=render_boxes
)
pipeline.start()
pipeline.join()

Find YOLOv8 Datasets

Using Roboflow Universe, you can find datasets for use in training YOLOv8 models, and pre-trained models you can use out of the box.

You can train a YOLOv8 model using the Ultralytics command line interface.

To train a model, install Ultralytics:

pip install ultralytics

Then, use the following command to train your model:

 yolo task=detect
mode=train
model=yolov8s.pt
data=dataset/data.yaml
epochs=100
imgsz=640

Replace data with the name of your YOLOv8-formatted dataset. Learn more about the YOLOv8 format.

You can then test your model on images in your test dataset with the following command:

 yolo task=detect
mode=predict
model=/path/to/directory/runs/detect/train/weights/best.pt
conf=0.25
source=dataset/test/images

Once you have a model, you can deploy it with Roboflow.
