3.1 HWD-ADown模块的代码
try:from mmcv.cnn import build_activation_layer, build_norm_layerfrom mmcv.ops.modulated_deform_conv import ModulatedDeformConv2dfrom mmengine.model import constant_init, normal_init
except ImportError as e:pass

阅读YOLOv9添加模块教程或使用下文操作 1. 将YOLOv9工程中models下common.py文件中的最下行增加模块的代码。
2. 将YOLOv9工程中models下yolo.py文件中的第681行可能因版本变化而变化增加以下代码。 RepNCSPELAN4, SPPELAN, HWD_ADown}:3.3 运行配置文件
