I'm using

check_call(['dot', '-Tpng', 'tree.dot', '-o', 'tree.png'])

but I got

FileNotFoundError: [Errno 2] No such file or directory: 'dot'

When I specify the path to replace the 'dot' I got

PermissionError: [Errno 13] Permission denied

I used import os to check my current working directory, it is correct. Why it still says no such file?

Can you run the command from the terminal? – Klaus D. Jun 05 '17 at 04:58
Yes, I just tried in terminal. I tried to specify directory and set the directory, I got same errors as I got in Jupyter – Tyree Wang Jun 05 '17 at 06:45

Then your problem is unrelated to the Python code. It looks more like a graphwiz installation issue. – Klaus D. Jun 05 '17 at 06:50
