yolov5 c3ghost代码

根据提供的引用内容，可以得知yolov5 c3ghost的代码如下所示：

class C3Ghost(nn.Module):
    def __init__(self, c1, c2, n=1, s=1, norm_layer=nn.BatchNorm2d, act_layer=nn.ReLU):
        super(C3Ghost, self).__init__()
        c_ = int(c2 * 0.5)  # hidden channels
        self.cv1 = Conv(c1, c_, 1, 1, norm_layer=norm_layer, act_layer=act_layer)
        self.cv2 = Conv(c_, c1, 1, 1, norm_layer=norm_layer, act_layer=act_layer)
        self.cv3 = Conv(c_, c_, 3, s, norm_layer=norm_layer, act_layer=act_layer)
        self.cv4 = Conv(2 * c_, c2, 1, 1, norm_layer=norm_layer, act_layer=act_layer)
        self.m = nn.Sequential(*<span class="em">1</span><span class="em">2</span><span class="em">3</span>
