要使用Graphviz生成PyTorch网络结构图,需要安装Graphviz软件包和Python的Graphviz包。安装完成后,可以使用以下代码生成网络结构图:
```python
import torch
from torchviz import make_dot
# 定义网络
class Net(torch.nn.Module):
def __init__(self):
super(Net, self).__init__()
self.conv1 = torch.nn.Conv2d(3, 6, kernel_size=5)
self.pool = torch.nn.MaxPool2d(kernel_size=2, stride=2)
self.conv2 = torch.nn.Conv2d(6, 16, kernel_size=5)
self.fc1 = torch.nn.Linear(16 * 5 * 5, 120)
self.fc2 = torch.nn.Linear(120, 84)
self.fc3 = torch.nn.Linear(84, 10)
def forward(self, x):
x = self.pool(torch.nn.functional.relu(self.conv1(x)))
x = self.pool(torch.nn.functional.relu(self.conv2(x)))
x = x.view(-1, 16 * 5 * 5)
x = torch.nn.functional.relu(self.fc1(x))
x = torch.nn.functional.relu(self.fc2(x))
x = self.fc3(x)
return x
# 创建随机输入
x = torch.randn(1, 3, 32, 32)
# 创建网络实例
net = Net()
# 生成网络结构图
dot = make_dot(net(x), params=dict(net.named_parameters()))
# 保存为PDF文件
dot.render('net', format='pdf')
```
运行以上代码后,会生成一个名为“net.pdf”的PDF文件,其中包含了生成的网络结构图。
