I use jypyter notebook to write code.
in my code, there are
!dot -Tpng DecisionTree4.dot -o DecisionTree4.png
after I installed dot by conda install graphviz, I have checked the place it is installed, it succeeds. the dot.exe located in E:\Program Files\Anaconda3\envs\comp47350py37\Library\bin\graphviz
and then I just follow a guideline I found online to add the file location into my environment variables: Variable is "PATH" and Value is "E:\Program Files\Anaconda3\envs\comp47350py37\Library\bin\graphviz"
Now, my problems became:
'E:\Program' is not recognized as an internal or external command, operable program or batch file.
And even I deleted the file path that I added into "PATH" and restarted my computer, it is still like this.
and also I have tried to use "progra~1" to replace "Program Files" and quoted 'Program Files' or all the path by single quotation(double isn't accepted by environment variables), but all of them didn't work.
How could I solve this and make !dot -Tpng DecisionTree4.dot -o DecisionTree4.png work?
I install graphviz from http://www.graphviz.org/download/ and install it in "C" then add it to my environment variables
and in my anaconda terminal, use "condo uninstall graphviz" now it could work
