Solution 1

先安裝graphviz否則會出現類似："dot" not found in path 的問題

安裝graphviz不要用pip install安裝，否則還是會找不到可執行程序

安裝：sudo apt-get insall graphviz

然后安裝pydot：pip install pydot

其中pyparsing會自動安裝

 

 Solution 2

If you have Anaconda installed the simplest way to go about this is to run the following from CMD:

conda install pydot-ng 

conda install graphviz
