安装pip install pydot、pydot-ng、graphviz,然后可视化模型
结果出现了错误,该如何解决,该错误和Exception: "dot.exe" not found in path.往往一起出现,解决方法相近。
我的解决
pip install pydot==1.2.3
pip install pydot-ng
graphviz的安装去[网址](https://www.graphviz.org/download/)
一直next(我装在C:/Program Files (x86)/Graphviz2.38/bin/)
添加此路径到环境变量
重启电脑(不然不行)
附:我还改了pydot.py --> class Dot(Graph): --> self.prog = 'dot.exe'(原来self.prog = 'dot'),不修改也许也行
