  1. #AlexNet 搭建
  2. import torch
  3. import torch.nn as nn
  4. class AlexNet(nn.Module):
  5.     def __init__(self):
  6.         super(AlexNet,self).__init__()
  7.         self.features=nn.Sequential(
  8.             nn.Conv2d(3,96,11,4,0),
  9.             nn.ReLU(True),
  10.             nn.MaxPool2d(3,2),
  11.             nn.Conv2d(96,256,5,1,2),
  12.             nn.ReLU(True),
  13.             nn.MaxPool2d(3,2),
  14.             nn.Conv2d(256,384,3,1,1),
  15.             nn.ReLU(True),
