I confirm what @guifeliper wrote work also on MacOS: you have to install graphviz on the system (brew install graphviz
) and not with Pip.

I solved it by installing pydot and graphiz with command
sudo apt install python-pydot python-pydot-ng graphviz
ref
from data-analysis.
This worked for me in virtual machine with anaconda:
sudo apt install graphviz
from data-analysis.
Same error here. after i install pydot and graphviz, still getting the error. Any advise on how to solve this? Thanks!

@jyoz90 you need to download the binary as well, that worked for me.
apk add --update --no-cache graphviz
from data-analysis.

Any idea why this is needed?
Installing via homebrew simply installs the binary in /usr/local/Cellar as opposed to pip which installs in /usr/local/lib/python@version/site-packages.
Both are available on PATH so i struggle to see why there would be a difference, even though there definitely is..

sudo apt install graphviz

The solution using "brew install graphviz" works very fine after trying to do something in Python. Thankyou @guifeliper

我通过使用命令ref安装pydot和graphiz解决了它
sudo apt install python-pydot python-pydot-ng graphviz
from data-analysis.

I 'brew install graphviz' , but still has this problem. what I did is following the introduction to statistic learning by python, before this code, there is a code to find the location of graphviz
find the location of graphviz so dot.exe is in the PATH
import os
common_path = os.path.commonpath([path for path in os.environ["PATH"].split(';') if 'Anaconda' in path])
dot_path = os.path.join(common_path, 'Library', 'bin', 'graphviz')
os.environ["PATH"] += os.pathsep + dot_path
but my case is no 'Anaconda' capitalized A, I used 'anaconda' instead, that's all.
Then I got the error message.

While in the virtual environment, the following installation methods does not works
sudo apt install python-pydot python-pydot-ng graphviz
from data-analysis.

What about Red Hat

What about
Red Hat
system?
This worked for me on Fedora 36
sudo dnf install graphviz

I confirm what @guifeliper wrote work also on MacOS: you have to install graphviz on the system (
brew install graphviz
) and not with Pip.
And the Homebrew command from @vlavorini works with Jupyter Notebook as well. Thanks!

I confirm that this works on macbook. Thank you so much
