你好,我是一名初学者,如果我想得到经过我自己改良的预训练模型,请问我应该去哪里修改yolov8的对应的函数部分(就是修改诸如损失函数之类的),然后在得到不同于yolov8n.pt的不同的预训练模型,我是在github上将ultralytics-main文件夹整个下载下来了,但我找不到相应的部分😭 |

您好,请问yolov8怎么做增量训练。就比如我需要基于yolov8n.pt上训练识别一个个性化的水管。然后训练出来的模型不仅仅要能识别水管还要能识别本身yoloV8n.pt就有的人、猫、杯子等。就是本身yolov8n.pt上的都不被抹除,应该怎么操作 |

你好,這是我的代碼:from ultralytics import YOLO Load the YOLO modelmodel = YOLO('D:/yolov7-0.1/ultralytics-main/ultralytics/models/yolo/pose/runs/detect/train4/weights/best.pt') Predict on the videoresults = model.predict(source="C:/Users/whpd/Desktop/h.mp4", conf=0.35, iou=0.35, show=False, save=True) |

关于深度学习yolov8我有几个个疑问,我这个是官方的分割模型的训练参数,请问这两个地方(yolov8n-seg.pt)和(yolov8n.pt)为什么不一样? Load a modelmodel = YOLO("yolov8n-seg.yaml") # build a new model from YAML Train the modelresults = model.train(data="coco8-seg.yaml", epochs=100, imgsz=640) Load a modelmodel = YOLO("yolov8n-seg.pt") # load a pretrained model (recommended for training) Train the modelresults = model.train(data="crack-seg.yaml", epochs=100, imgsz=640) |

您好!我们想要实现对于建筑工地中特定物体的监视,比如工人、挖掘机等,请问您有推荐的YOLO版本吗。我们想要将这个程序集成到开发板中以达到摄像头能够实时监测的目的,但是这是硬件的范畴,对于我们来说是知识盲区了,请问您有推荐的教程或者说文档推荐吗。 |

自训练的模型,通过脚本转换为 ONNX 模型后,无法在 开启了 CUDA 的 OpenGL 下调用,调用结果中位置信息全部为空,但是置信度时正确的,这个是我处理存在问题嘛,直接转换官方的 pt 模型也一样无法正常工作,这是我的转换代码: from ultralytics import YOLO if name == 'main': 期待任何建议 ~ |
