模型前提：采用Efficient VIT改进yolov5

Q：运行训练时报错：

NameError: name 'DWConvTranspose2d' is not defined

S：在common.py下创建该类：

class DWConvTranspose2d(nn.ConvTranspose2d):
    # Depth-wise transpose convolution
    def __init__(self, c1, c2, k=1, s=1, p1=0, p2=0):  # ch_in, ch_out, kernel, stride, padding, padding_out
        super().__init__(c1, c2, k, s, p1, p2, groups=math.gcd(c1, c2))
