![]() ![]() Number of epochs to wait without improvement in validation metrics before early stopping the training. Useful for time-constrained training scenarios. If set, this overrides the epochs argument, allowing training to automatically stop after the specified duration. ![]() Adjusting this value can affect training duration and model performance. Each epoch represents a full pass over the entire dataset. This file contains dataset-specific parameters, including paths to training and validation data, class names, and number of classes. Path to the dataset configuration file (e.g., coco128.yaml). Essential for defining the model structure or initializing weights. Careful tuning and experimentation with these settings are crucial for optimizing performance. Additionally, the choice of optimizer, loss function, and training dataset composition can impact the training process. Key training settings include batch size, learning rate, momentum, and weight decay. These settings influence the model's performance, speed, and accuracy. The training settings for YOLO models encompass various hyperparameters and configurations used during the training process. Remember that checkpoints are saved at the end of every epoch by default, or at fixed interval using the save_period argument, so you must complete at least 1 epoch to resume a training run. If the resume argument is omitted or set to False, the train function will start a new training session. # Resume an interrupted training yolo train resume model =path/to/last.ptīy setting resume=True, the train function will continue training from where it left off, using the state stored in the 'path/to/last.pt' file. pt file containing the partially trained model weights.īelow is an example of how to resume an interrupted training using Python and via the command line: You can easily resume training in Ultralytics YOLO by setting the resume argument to True when calling the train method, and specifying the path to the. This allows you to continue the training process seamlessly from where it was left off. When training is resumed, Ultralytics YOLO loads the weights from the last saved model and also restores the optimizer state, learning rate scheduler, and the epoch number. This can come in handy in various scenarios, like when the training process has been unexpectedly interrupted, or when you wish to continue training a model with new data or for more epochs. Resuming training from a previously saved state is a crucial feature when working with deep learning models. ![]() For more detailed guidance and advanced configuration options, please refer to the PyTorch MPS documentation. While leveraging the computational power of the M1/M2 chips, this enables more efficient processing of the training tasks. # Start training from a pretrained *.pt model using GPUs 0 and 1 yolo detect train data =coco128.yaml model =yolov8n.pt epochs = 100 imgsz = 640 device =mps
