ubuntu下安装神经网络绘图工具Graphviz

1、Ubuntu下安装graphviz

sudo apt-get install graphviz

2、神经网络的绘图

digraph G {
       rankdir=LR
       splines=line
       nodesep=.05;
       node [label=""];

       subgraph cluster_0 {
          color=white;
          node [style=solid,color=blue4, shape=circle];
          x1 x2;
          label = "layer 1";
      }

      subgraph cluster_1 {
          color=white;
          node [style=solid,color=red2, shape=circle];
          a12 a22 a32;
          label = "layer 2";
      }

      subgraph cluster_2 {
          color=white;
          node [style=solid,color=seagreen2, shape=circle];
          O1 O2 ;
          label="layer 3";
      }

      x1 -> a12
      x1 -> a22
      x1 -> a32

      x2 -> a12
      x2 -> a22
      x2 -> a32

      a12 -> O1
      a22 -> O1
      a32 -> O1
}

3、运行

dot -Tsvg nn.dot -o nn.svg
#dot -Tpng nn.dot -o nn.png 图片格式可更改

4、得到的图片如下：
