AttributeError: Can‘t get attribute ‘SPPF‘ on ＜module ‘models.common‘ from ‘H:\\yolov5-5.0\\models\\

yolo报错

解决方案：model/common.py里面去找到这个SPPF的类,把它拷过来到你这个Tags5的model/common.py里面,这样你的代码就也有这个类了,还要引入一个warnings包就行了！

有的同学找不到SPPF这个类，那我现在直接粘贴在这里，你们只需要复制到你们的common.py里面即可，记得把import warnings放在上面去：

import warnings
class SPPF(nn.Module):
    # Spatial Pyramid Pooling - Fast (SPPF) layer for YOLOv5 by Glenn Jocher
    def __init__(self, c1, c2, k=5):  # equivalent to SPP(k=(5, 9, 13))
        super().__init__()
        c_ = c1 // 2  # hidden channels
        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')  # suppress torch 1.9.0 max_pool2d() warning
            y1 = self.m(x)
            y2 = self.m(y1)
            return self.cv2(torch.cat([x, y1, y2, self.m(y2)], 1))
