在pycharm的命令终端输入

yolo task=detect mode=train model=pretrained/yolov8l.pt data=ultralytics/cfg/datasets/A_my_data.yaml batch=32 epochs=3 imgsz=100 workers=0 device=CPU cache=True

指令进行训练的时候出现报错

 raise RuntimeError(emojis(f"Dataset '{clean_url(self.args.data)}' error ❌ {e}")) from e
RuntimeError: Dataset 'ultralytics/cfg/datasets/A_my_data.yaml' error
Dataset 'ultralytics/cfg/datasets/A_my_data.yaml' images not found , missing path 'C:\ai\person_train\yolov8\images\val'
原本images和labels这两个文件的路径是'C:\ai\person_train\yolov8\demo1

现将两个文件放在C:\ai\person_train\yolov8目录下解决问题。或者修改路径。
