私はJupyterのグラフで作業していますが、networkxは適切なグラフ表現を提供しないため、GraphVizパッケージを使用しようとしましたそこに：https://github.com/chebee7i/nxpd。PATHにGraphVizフォルダを追加してもGraphViz実行ファイルにアクセスできない
私が最初nxpdパッケージをインポートしたが、私は引き分け（）関数をしようとしたとき、私はこのエラーに直面していました：
InvocationException: GraphViz's executables not found.
私は最初、それが私があるpygraphvizパッケージを、インストールしていなかったためと考えられ私が実行しようとしましたが、私は今、このエラーに直面するもの：

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.
StackOverflowの上で検索した後、私はこれらのディレクトリを追加しました：
D:\Program Files (x86)\Anaconda3\Lib\site-packages\graphviz\bin
D:\Program Files (x86)\Anaconda3\Lib\site-packages\graphviz\include\graphviz
私のPATHには、何も変更されませんでした。
ありがとうございました。
