AttributeError: Can't get attribute 'SPPF' on <module 'models.common' from 'D:\\Users\\WangZL\\Desktop\\yolov5-5.0\\models\\common.py'>

在您提供的引用中，出现了一个错误信息：AttributeError: Can't get attribute 'SPPF' on <module 'models.common' from 'D:\\Users\\WangZL\\Desktop\\yolov5-5.0\\models\\common.py'>。这个错误是由于在models.common模块中找不到名为'SPPF'的属性所引起的。为了解决这个问题，可以尝试以下方法：

方法一：在models/common.py中增加一个类'SPPF'。这个类是用来实现Spatial Pyramid Pooling - Fast (SPPF)层的。通过在models/common.py中添加这个类，可以解决找不到'SPPF'属性的问题。

具体的代码修改如下：

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))

通过添加这个类，您应该能够解决在<module 'models.common' from 'D:\\Users\\WangZL\\Desktop\\yolov5-5.0\\models\\common.py'>中找不到'SPPF'属性的问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
