【graphviz】failed to execute [‘dot’, ‘-Tsvg’], make sure the Graphviz executables are on your systems

在jupyter lab中进行数据可视化时候报错:failed to execute [‘dot’, ‘-Tsvg’], make sure the Graphviz executables are on your systems

之前用pip install 命令装过这个安装包,查证后是因为没有添加环境变量

先用 pip show graphviz找到安装路径

然后添加环境变量,还是无效

conda install graphviz 无效
conda install python-graphviz,有效。。。
