我正在Jupyter上開發圖表，並且由於networkx沒有提供良好的圖形表示形式，我嘗試使用GraphViz軟件包，更具體地說找到了發現的軟件包有：https://github.com/chebee7i/nxpd。無法訪問GraphViz可執行文件，即使在PATH中添加GraphViz文件夾
我第一次進口nxpd包，但是當我試圖在draw（）函數，我遇到這個錯誤：
InvocationException: GraphViz's executables not found.
我首先想到的是它，因爲我沒有安裝pygraphviz包，這是我試圖這樣做，但我現在面對這樣的錯誤：

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.
在計算器上搜索後，我添加這些目錄：
D:\Program Files (x86)\Anaconda3\Lib\site-packages\graphviz\bin
D:\Program Files (x86)\Anaconda3\Lib\site-packages\graphviz\include\graphviz
我的路徑，但它沒有改變任何東西。
謝謝你的幫助。
