YOLOv8 is a unified computer vision framework that supports three tasks—object detection, image segmentation, and classification—in a single model, offering faster training and more lightweight architecture than previous versions. To train YOLOv8 on custom datasets, users must prepare data in the YOLO format with specific folder structures (train/validation/test containing images and corresponding label files) and a data.yaml configuration file specifying dataset paths and class names. The model can be trained using either command-line interface or Python scripts, with training commands requiring parameters like task type, model variant, data configuration, epochs, and image size. After training, the best.pt weights are saved in the runs directory, and the model can be validated and used for inference on new images.
