PyTorch Tutorial 17 - Saving and Load...

教程Python代码如下：

import torch.nn as nn

# 定义卷积神经网络模型

class ConvNet(nn.Module):

  def __init__(self):

    super(ConvNet, self).__init__()

    self.conv1 = nn.Conv2d(3, 16, kernel_size=3, stride=1, padding=1)

    self.conv2 = nn.Conv2d(16, 32, kernel_size=3, stride=1, padding=1)

    self.conv3 = nn.Conv2d(32, 64, kernel_size=3, stride=1, padding=1)

    self.pool = nn.MaxPool2d(kernel_size=2, stride=2)

    self.fc1 = nn.Linear(64 * 28 * 28, 512)

    self.fc2 = nn.Linear(512, 5)

    self.dropout = nn.Dropout(0.5)

  def forward(self, x):

    x = self.pool(nn.functional.relu(self.conv1(x)))

    x = self.pool(nn.functional.relu(self.conv2(x)))

    x = self.pool(nn.functional.relu(self.conv3(x)))

    x = x.view(-1, 64 * 28 * 28)

    x = self.dropout(nn.functional.relu(self.fc1(x)))

    x = self.fc2(x)

    return x
