以下是RestNet-18的Pytorch工具：https : //github.com/pytorch/vision/blob/master/torchvision/models/resnet.py 以下是ResNet-18的结构，谁知道为什么这个网络有18个层？

ResNet (
  (conv1): Conv2d(3, 64, kernel_size=(7, 7), stride=(2, 2), padding=(3, 3), bias=False)
  (bn1): BatchNorm2d(64, eps=1e-05, momentum=0.1, affine=True)
  (relu): ReLU (inplace)
  (maxpool): MaxPool2d (size=(3, 3), stride=(2, 2), padding=(1, 1), dilation=(1, 1))
  (layer1): Sequential (
    (0): BasicBlock (
      (conv1): Conv2d(64, 64, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1), bias=False)
