一、模块介绍

论文速览：

通过将内核尽可能全局化，现代 ConvNet 在计算机视觉任务中显示出巨大的潜力。然而，深度神经网络（DNN）中多阶博弈论交互的最新进展揭示了现代ConvNet的表示瓶颈，即随着核大小的增加，表达互没有得到有效编码。为了应对这一挑战，我们提出了一个新的现代 ConvNet 系列，称为 MogaNet，用于在纯基于 ConvNet 的模型中进行判别视觉表示学习，并具有良好的复杂性-性能权衡。MogaNet将概念上简单而有效的卷积和门控聚合封装到一个紧凑的模块中，其中有效地收集了判别特征并自适应地进行情境化。与 ImageNet 上最先进的 ViT 和 ConvNet 以及各种下游视觉基准测试（包括 COCO 对象检测、ADE20K 语义分割、2D 和 3D 人体姿态估计和视频预测）相比，MogaNet 表现出强大的可扩展性、令人印象深刻的参数效率和具有竞争力的性能。

2.2更改yaml文件 (以自研模型为例)

yam文件解读：YOLO系列 “.yaml“文件解读_yolo yaml文件-CSDN博客

打开更改ultralytics/cfg/models/11路径下的YOLOv11.yaml文件，替换原有模块。

os.environ['KMP_DUPLICATE_LIB_OK'] = 'TRUE'if __name__ == '__main__':model = YOLO(model='ultralytics/cfg/models/xy_YOLO/xy_yolov1.yaml')# model = YOLO(model='ultralytics/cfg/models/11/yolo11l.yaml')model.train(data='./datasets/data.yaml', epochs=1, batch=1, device='0', imgsz=320, workers=1, cache=False,amp=True, mosaic=False, project='run/train', name='exp',)
