在Pytorch中能够应用tensorboardX画出网络结构图，但总感觉不太好看。pytorchviz 仿佛是一个不错的抉择。

应用办法：

from torchviz import make_dotfrom torch.autograd import Variablenet = Model()x = Variable(torch.randn(3,32,32))vis_graph = make_dot(net(x), params=dict(net.named_parameters()))vis_graph.directory = "Net_Structure"   # 设置可视化文件的导出门路vis_graph.format = "png"       # 如果不加这一句，生成的则是pdfvis_graph.view()

如果单纯地pip install torchviz，会报以下谬误：

graphviz.backend.ExecutableNotFound: failed to execute ['dot', '-Tpdf', '-O', 'Digraph.gv'], make sure the Graphviz executables are on your systems' PATH

正确的办法：

  1. 下载package并解压到本地，例如D:/test . 我下载的是：这个
  2. Add D:\test\Graphviz\bin to User path
  3. Add D:\test\Graphviz\bin\dot.exe to System Path
  4. 重启计算机

再运行下面的程序后就会发现网络结构图会呈现在一个pdf或png中
