只能使用yolov5m吗 #30

当使用https://github.com/ultralytics/yolov5中的yolov5m.pt时,报错tributeError: Can't get attribute 'C3' on <module 'models.common' from 'Yolov5-deepsort-inference/models/common.py'>

加个这个

在最上面需要引入warnings库

import warnings

class C3(nn.Module):

CSP Bottleneck with 3 convolutions

def __init__(self, c1, c2, n=1, shortcut=True, g=1, e=0.5):  # ch_in, ch_out, number, shortcut, groups, expansion
    super(C3, self).__init__()
    c_ = int(c2 * e)  # hidden channels
    self.cv1 = Conv(c1, c_, 1, 1)
    self.cv2 = Conv(c1, c_, 1, 1)
    self.cv3 = Conv(2 * c_, c2, 1)  # act=FReLU(c2)
    self.m = nn.Sequential(*[Bottleneck(c_, c_, shortcut, g, e=1.0) for _ in range(n)])
    # self.m = nn.Sequential(*[CrossConv(c_, c_, 3, 1, g, 1.0, shortcut) for _ in range(n)])

def forward(self, x):
    return self.cv3(torch.cat((self.m(self.cv1(x)), self.cv2(x)), dim=1))

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))
