使用GraphViz添加多重编号时，无法从点渲染SVG图

Question

我试图使用：grv.render（'Neato'，'svg'，'graph.dot'）渲染我的点文件。

点文件位于问题的底部。（很大，1500多行）。

Magjac的

我运行此代码的Heroku应用程序正在运行Python 3.9，GraphViz Python模块0.2和GraphViz 2.43。

我尝试了多个ESEP和SEP配置。 花键被关闭工作，因此错误似乎来自多重编号的路由，因为此问题仅在我的图表具有它们时发生。

错误读取的图形与工作正常，节点大小的警告太大：

2.43.0很旧（几年）。如果您安装了GraphViz（4.0）的新版本，则可以正常工作。不幸的是，“安装较新版本”可以进行一些真正的工作。
