运行YOLOv5出现报错找不到SPPF错误，进行解决AttributeError: Can‘t get attribute ‘SPPF‘ on ＜module ‘models.common‘ from

运行YOLOv5时报错：AttributeError: Can't get attribute 'SPPF' on <module 'models.common' from 'D:\PyCharmProject\yolov5-5.0\yolov5-5.0\models\common.py'>

解决办法如下：首先找到YOLOv5下的这个文件打开

 打开文件往下翻找到class SPP这一行，我的是在166行，在这一行上面添加下面的程序添加class SPPF

class SPPF(nn.Module):
    def __init__(self, c1, c2, k=5):
        super().__init__()
        c_ = c1 // 2
        self.cv1 = Conv(c1, c_, 1, 1)
        self.cv2 = Conv(c_ * 4, c2, 1, 1)
        self.m = nn.MaxPool2d(kernel_size=k, stride=1, padding=k // 2)

    def forward(self, x):
        x = self.cv1(x)
        with warnings.catch_warnings():
            warnings.simplefilter('ignore')
            y1 = self.m(x)
            y2 = self.m(y1)
            return self.cv2(torch.cat([x, y1, y2, self.m(y2)], 1))

如图所示：

 

再运行程序就不会报错啦。
