@ChenJian7578 to disable mosaic augmentation in YOLOv5 during the last few epochs, you can modify the training script to adjust the mosaic parameter in the data augmentation settings. You can manually set it to False in the hyp.scratch-low.yaml file or adjust it dynamically in the training loop. For more detailed guidance, you might want to explore the training scripts and augmentation settings in the repository.
