Предсказывай

Predict mode is used for making predictions using a trained YOLO11 model on new images or videos. In this mode, the model is loaded from a checkpoint file, and the user can provide images or videos to perform inference. The model predicts the classes and locations of objects in the input images or videos.

Benchmark mode is used to profile the speed and accuracy of various export formats for YOLO11. The benchmarks provide information on the size of the exported format, its mAP50-95 metrics (for object detection, segmentation, and pose) or accuracy_top5 metrics (for classification), and the inference time in milliseconds per image across various formats like ONNX, OpenVINO, TensorRT, and others. This information can help users choose the optimal export format for their specific use case based on their requirements for speed and accuracy.

ВОПРОСЫ И ОТВЕТЫ

How do I train a custom object detection model with Ultralytics YOLO11?

Training a custom object detection model with Ultralytics YOLO11 involves using the train mode. You need a dataset formatted in YOLO format, containing images and corresponding annotation files. Use the following command to start the training process:

from ultralytics import YOLO

# Load a pre-trained YOLO model (you can choose n, s, m, l, or x versions)
model = YOLO("yolo11n.pt")

# Start training on your custom dataset
model.train(data="path/to/dataset.yaml", epochs=100, imgsz=640)

# Train a YOLO model from the command line
yolo train data=path/to/dataset.yaml epochs=100 imgsz=640

За более подробными инструкциями ты можешь обратиться к руководству по тренировкамUltralytics .

What metrics does Ultralytics YOLO11 use to validate the model's performance?

Ultralytics YOLO11 uses various metrics during the validation process to assess model performance. These include:

• mAP (средняя средняя точность): Здесь оценивается точность обнаружения объектов.
• IOU (Intersection over Union): Измеряет перекрытие между предсказанными и истинными границами.
• Precision and Recall: Precision measures the ratio of true positive detections to the total detected positives, while recall measures the ratio of true positive detections to the total actual positives.

Ты можешь выполнить следующую команду, чтобы запустить проверку:

from ultralytics import YOLO

# Load a pre-trained or custom YOLO model
model = YOLO("yolo11n.pt")

# Run validation on your dataset
model.val(data="path/to/validation.yaml")

# Validate a YOLO model from the command line
yolo val data=path/to/validation.yaml

Подробнее об этом читай в руководстве по валидации.

How can I export my YOLO11 model for deployment?

Ultralytics YOLO11 offers export functionality to convert your trained model into various deployment formats such as ONNX, TensorRT, CoreML, and more. Use the following example to export your model:

from ultralytics import YOLO

# Load your trained YOLO model
model = YOLO("yolo11n.pt")

# Export the model to ONNX format (you can specify other formats as needed)
model.export(format="onnx")

# Export a YOLO model to ONNX format from the command line
yolo export model=yolo11n.pt format=onnx

Подробные шаги для каждого формата экспорта можно найти в руководстве по экспорту.

What is the purpose of the benchmark mode in Ultralytics YOLO11?

Benchmark mode in Ultralytics YOLO11 is used to analyze the speed and accuracy of various export formats such as ONNX, TensorRT, and OpenVINO. It provides metrics like model size, mAP50-95 для обнаружения объектов, а также время вывода для различных аппаратных установок, что поможет тебе выбрать наиболее подходящий формат для твоих потребностей в развертывании.

from ultralytics.utils.benchmarks import benchmark

# Run benchmark on GPU (device 0)
# You can adjust parameters like model, dataset, image size, and precision as needed
benchmark(model="yolo11n.pt", data="coco8.yaml", imgsz=640, half=False, device=0)

# Benchmark a YOLO model from the command line
# Adjust parameters as needed for your specific use case
yolo benchmark model=yolo11n.pt data='coco8.yaml' imgsz=640 half=False device=0

How can I perform real-time object tracking using Ultralytics YOLO11?

Real-time object tracking can be achieved using the track mode in Ultralytics YOLO11. This mode extends object detection capabilities to track objects across video frames or live feeds. Use the following example to enable tracking:

from ultralytics import YOLO

# Load a pre-trained YOLO model
model = YOLO("yolo11n.pt")

# Start tracking objects in a video
# You can also use live video streams or webcam input
model.track(source="path/to/video.mp4")

# Perform object tracking on a video from the command line
# You can specify different sources like webcam (0) or RTSP streams
yolo track source=path/to/video.mp4
