Ultralytics YOLOv8 Modes
Ultralytics YOLOv8 supports several modes that can be used to perform different tasks. These modes are:
Train: For training a YOLOv8 model on a custom dataset.
Val: For validating a YOLOv8 model after it has been trained.
Predict: For making predictions using a trained YOLOv8 model on new images or videos.
Export: For exporting a YOLOv8 model to a format that can be used for deployment.
Track: For tracking objects in real-time using a YOLOv8 model.
Benchmark: For benchmarking YOLOv8 exports (ONNX, TensorRT, etc.) speed and accuracy.
Train
Train mode is used for training a YOLOv8 model on a custom dataset. In this mode, the model is trained using the specified dataset and hyperparameters. The training process involves optimizing the model's parameters so that it can accurately predict the classes and locations of objects in an image.

Val
Val mode is used for validating a YOLOv8 model after it has been trained. In this mode, the model is evaluated on a validation set to measure its accuracy and generalization performance. This mode can be used to tune the hyperparameters of the model to improve its performance.

Predict
Predict mode is used for making predictions using a trained YOLOv8 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.

Export
Export mode is used for exporting a YOLOv8 model to a format that can be used for deployment. In this mode, the model is converted to a format that can be used by other software applications or hardware devices. This mode is useful when deploying the model to production environments.

Track
Track mode is used for tracking objects in real-time using a YOLOv8 model. In this mode, the model is loaded from a checkpoint file, and the user can provide a live video stream to perform real-time object tracking. This mode is useful for applications such as surveillance systems or self-driving cars.

Benchmark
Benchmark mode is used to profile the speed and accuracy of various export formats for YOLOv8. The benchmarks provide
information on the size of the exported format, its mAP50-95 metrics (for object detection and segmentation)
or accuracy_top5 metrics (for classification), and the inference time in milliseconds per image across various export
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.
