测试环境：cuda11.3 pytorch1.11 rtx3090 wsl2 ubuntu20.04
踩了很多坑，网上很多博主的代码根本跑不通，自己去github仓库复现修改的
网上博主的代码日常出现cpu,gpu混合，或许是人家分布式训练了，哈哈哈
下面上干货吧，宝子们点个关注，点个赞，没有废话
yolov8_yaml文件修改(目标检测就修改

self.m = SwinTransformer2Block(c_, c_, num_heads, n)

y1 = self.m(x1)
y2 = self.cv2(x1)
return self.cv3(torch.cat((y1, y2), dim=1))随后在这个目录的init.py里面把你的新的东西放进去
from .block import (C1, C2, C3, C3TR, DFL, SPP, SPPF, Bottleneck, BottleneckCSP, C2f, C3Ghost, C3x, GhostBottleneck,

'GCT','C3STR','SwinV2_CSPB')然后去task.py
在导包那里，把这个导入进去
rom ultralytics.nn.modules import (AIFI, C1, C2, C3, C3TR, SPP, SPPF, Bottleneck, BottleneckCSP, C2f, C3Ghost, C3x,
Classify, Concat, Conv, Conv2, ConvTranspose, Detect, DWConv, DWConvTranspose2d,
Focus, GhostBottleneck, GhostConv, HGBlock, HGStem, Pose, RepC3, RepConv,
RTDETRDecoder ,Segment,CBAM,GAM_Attention,ResBlock_CBAM,GCT,C3STR,SwinV2_CSPB)然后同样在task.py里面搜索if m in
把你的新的swin模块放进去
if m in (Classify, Conv, ConvTranspose, GhostConv, Bottleneck, GhostBottleneck, SPP, SPPF, DWConv, Focus,
BottleneckCSP, C1, C2, C2f, C3, C3TR, C3Ghost, nn.ConvTranspose2d, DWConvTranspose2d, C3x, RepC3
,CBAM , GAM_Attention ,ResBlock_CBAM,GCT,C3STR,SwinV2_CSPB):最后
命令行：python setup.py install 注册
命令行：你的训练命令
