General Questions
- What is YOLOv8?
YOLOv8 is the latest iteration of the You Only Look Once (YOLO) object detection framework developed by Ultralytics. It builds upon the successes of previous YOLO versions, introducing advancements in speed, accuracy, and flexibility.
- What are the benefits of using YOLOv8?
YOLOv8 offers several key benefits:
- How do I get started with YOLOv8?
- Install the Ultralytics library: `pip install ultralytics`
- Explore the documentation and code examples on the Ultralytics website.
- Follow the tutorials available on the Ultralytics website or GitHub repository.
- Where can I find pre-trained YOLOv8 models?
The Ultralytics Hub offers a vast repository of pre-trained YOLOv8 models for various datasets and tasks.
Training and Evaluation
- How do I train a YOLOv8 model?
Use the `train.py` script within the Ultralytics library, providing your dataset configuration (`data.yaml`) and model configuration (`model.yaml`) files.
- What metrics should I use to evaluate my model?
Common metrics for object detection include:
- What are some common training errors and how to fix them?
- GPU Memory Errors: Reduce batch size, model size, or image resolution.
- Dataset Loading Errors: Verify dataset paths and format.
- Hyperparameter Tuning: Experiment with different learning rate, epochs, and optimizer settings.
Inference and Deployment
- How do I perform inference with a trained YOLOv8 model?
Load your model using `torch.hub.load('ultralytics/yolov8', 'your_trained_model')`, then run inference on your input data.
- How do I deploy my YOLOv8 model?
YOLOv8 models can be deployed on various platforms:
- What are some common deployment challenges?
- Environment Compatibility: Ensure your deployment environment meets library and hardware requirements.
