我正在嘗試conv1根據下面的代碼和架構可視化層的 cnn 網絡特征圖。它在沒有 DataParallel 的情況下正常工作，但是當我激活model = nn.DataParallel(model)它時，它會引發錯誤：“DataParallel”對象沒有屬性“conv1”。任何建議表示贊賞。class Model(nn.Module):    def __init__(self, kernel, num_filters, res = ResidualBlock):        super(Model, self).__init__()                self.conv0 = nn.Sequential(            nn.Conv2d(4, num_filters, kernel_size = kernel*3,                        padding = 4),            nn.BatchNorm2d(num_filters),            nn.ReLU(inplace=True))                self.conv1 = nn.Sequential(            nn.Conv2d(num_filters, num_filters*2, kernel_size = kernel,                       stride=2, padding = 1),            nn.BatchNorm2d(num_filters*2),            nn.ReLU(inplace=True))                self.conv2 = nn.Sequential(            nn.Conv2d(num_filters*2, num_filters*4, kernel_size = kernel, stride=2, padding = 1),            nn.BatchNorm2d(num_filters*4),            nn.ReLU(inplace=True))                       self.tsconv0 = nn.Sequential(            nn.ConvTranspose2d(num_filters*4, num_filters*2, kernel_size = kernel, padding = 1),            nn.Upsample(scale_factor=2, mode='bilinear', align_corners=True),            nn.ReLU(inplace=True),            nn.BatchNorm2d(num_filters*2))        self.tsconv1 = nn.Sequential(            nn.ConvTranspose2d(num_filters*2, num_filters, kernel_size = kernel, padding = 1),            nn.Upsample(scale_factor=2, mode='bilinear', align_corners=True),            nn.ReLU(inplace=True),            nn.BatchNorm2d(num_filters))                self.tsconv2 = nn.Sequential(            nn.Conv2d(num_filters, 1, kernel_size = kernel*3, padding = 4, bias=False),            nn.ReLU(inplace=True))model = Model(kernel, num_filters)model = nn.DataParallel(model)
