[英]Can't access GraphViz executables, even after adding GraphViz folder in PATH
我正在使用Jupyter进行图形处理，并且由于networkx无法提供良好的图形表示，我尝试使用GraphViz软件包，更具体地说是使用在那里找到的软件包： https : //github.com/chebee7i/nxpd 。
我首先导入了nxpd包，但是当我尝试draw（）函数时，遇到了这个错误：
InvocationException：找不到GraphViz的可执行文件。
我首先以为是因为我没有安装pygraphviz软件包，这是我试图做的，但是现在我遇到了这个错误：

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
在StackOverflow上搜索之后，我添加了以下目录：
D:\Program Files (x86)\Anaconda3\Lib\site-packages\graphviz\bin
D:\Program Files (x86)\Anaconda3\Lib\site-packages\graphviz\include\graphviz
到我的路径，但没有任何改变。
谢谢您的帮助。
您是否使用以下命令在命令提示符中添加了路径？
PATH = %PATH%;<new path stuff>
还是使用“系统属性”中的环境变量添加了它？
我发现我需要使用系统属性来添加它，以使其在整个系统范围内起作用。 仅使用命令提示符添加时，它仍然不起作用。
尝试使用os.environ在jupyter笔记本本身中添加路径。
import os
os.environ["PATH"] += os.pathsep + 'C:/Program Files (x86)/Graphviz2.38/bin/'
是否可以在不向系统PATH添加任何内容的情况下解决“ InvocationException：找不到GraphViz的可执行文件”的问题？
[英]Can I resolve “InvocationException: GraphViz's executables not found” without adding anything to system PATH?
安装 Graphviz 2.38 后“运行时错误：确保 Graphviz 可执行文件位于系统路径上”

`pydot` 调用 GraphViz 失败。请安装 GraphViz 并确保其可执行文件在 $PATH 中
