"RuntimeError: Make sure the Graphviz executables are on your system's path" after installing Graphviz 2.38

Python Problem Overview

I downloaded Graphviz 2.38 MSI version and installed under folder C:\Python34, then I run pip install Graphviz, everything went well. In system's path I added C:\Python34\bin. When I tried to run a test script, in line filename=dot.render(filename='test'), I got a message

 RuntimeError: failed to execute ['dot', '-Tpdf', '-O', 'test'], make sure the Graphviz executables are on your systems' path

I tried to put "C:\Python34\bin\dot.exe" in system's path, but it didn't work, and I even created a new environment variable "GRAPHVIZ_DOT" with value "C:\Python34\bin\dot.exe", still not working. I tried to uninstall Graphviz and pip uninstall graphviz, then reinstall it and pip install again, but nothing works.

The whole traceback message is:

Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\graphviz\files.py", line 220, in render
    proc = subprocess.Popen(cmd, startupinfo=STARTUPINFO)
  File "C:\Python34\lib\subprocess.py", line 859, in __init__
    restore_signals, start_new_session)
  File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\Documents\Kissmetrics\curves and lines\eventNodes.py", line 56, in <module>
    filename=dot.render(filename='test')
  File "C:\Python34\lib\site-packages\graphviz\files.py", line 225, in render
    'are on your systems\' path' % cmd)
RuntimeError: failed to execute ['dot', '-Tpdf', '-O', 'test'], make sure the Graphviz executables are on your systems' path

Does anybody have any experience with it?

Python Solutions

Solution 1 - Python

You should install the graphviz package in your system (not just the python package). On Ubuntu you should try:

sudo apt-get install graphviz

Solution 2 - Python

import os
os.environ["PATH"] += os.pathsep + 'D:/Program Files (x86)/Graphviz2.38/bin/'

In windows just add these 2 lines in the beginning, where 'D:/Program Files (x86)/Graphviz2.38/bin/' is replaced by the address of where your bin file is.

That solves the problem.

Solution 3 - Python

This one solved the problem for me on MAC:

  brew install graphviz

Solution 4 - Python

For Windows:

Install windows package from: https://graphviz.gitlab.io/_pages/Download/Download_windows.html
Install python graphviz package
Add C:\Program Files (x86)\Graphviz2.38\bin to User path
Add C:\Program Files (x86)\Graphviz2.38\bin\dot.exe to System Path

This worked for me!

Solution 5 - Python

Try using:

conda install python-graphviz

The graphviz executable sit on a different path from your conda directory, if you use pip install graphviz.

Solution 6 - Python

Step 1: Install Graphviz binary

> Windows:

Download Graphviz from http://www.graphviz.org/download/
Add below to PATH environment variable (mention the installed graphviz version):

C:\Program Files (x86)\Graphviz2.38\bin
C:\Program Files (x86)\Graphviz2.38\bin\dot.exe

Close any opened Juypter notebook and the command prompt
Restart Jupyter / cmd prompt and test

> Linux:

sudo apt-get update
sudo apt-get install graphviz
or build it manually from http://www.graphviz.org/download/

Step 2: Install graphviz module for python

> pip:

pip install graphviz

> conda:

conda install graphviz

Solution 7 - Python

OSX Sierra, Python 2.7, Graphviz 2.38

Using pip install graphviz and conda install graphviz BOTH resolves the problem.

pip only gets path problem same as yours and conda only gets import error.

Solution 8 - Python

Just add below to your Environmental Variable(system) PATH on Windows

> C:\Program Files (x86)\Graphviz2.38\bin > > there, you can find .exe files

If not work

Find Graphviz2.38/bin folder in your Program Files not in python lib

Then, add to your PATH

It's important to find a folder where .exe files exist

Solution 9 - Python

This is showing some path issue:

pip install graphviz

So this worked for me:

sudo apt-get install graphviz

Solution 10 - Python

Using conda install graphviz and conda install python-graphviz to install GraphViz on Windows10 the path needed was C:/ProgramData/Anaconda3/Library/bin/graphviz/ for me. I.e. adding

import os
os.environ["PATH"] += os.pathsep + 'C:/ProgramData/Anaconda3/Library/bin/graphviz/'

solved the issue for me.

Solution 11 - Python

Try conda install graphviz. I had the same problem, I resolved it by mentioned command in MacOS.

Solution 12 - Python

On Ubuntu Linux this solved it for me:

pip install graphviz
sudo apt-get install graphviz

You could also try conda install -c conda-forge graphviz instead of pip if using Anaconda.

Solution 13 - Python

I'm on macOS Catalina 10.15.3, and I had a similar error: ExecutableNotFound: failed to execute ['dot', '-Tsvg'], make sure the Graphviz executables are on your systems' PATH

Fixed it with:

pip3 install graphviz AND brew install graphviz

Note the pip3 install will only return the success message Successfully installed graphviz-0.13.2 so we still need to run brew install to get graphviz 2.42.3 (as of 10 Mar 2020, 6PM).

Solution 14 - Python

conda install python-graphviz

For Windows, install the Python Graphviz which will include the executables in the path.

Solution 15 - Python

When solving this issue for myself, I used this GitHub tutorial, which analysed the cause of this issue. If we read in between the lines, it says it needs system as well as python graph viz. In addition to conda install, we would need to run:

conda install -c conda-forge python-graphviz

Then restart the kernel; it works like a charm.

Solution 16 - Python

Graphviz – download unzip in a particular place in the system (pip does not work in windows ) and include the bin folder in the path (‘set environment variables in windows’ OR) set manually in each program

import os os.environ["PATH"] += os.pathsep + 'C:/GraphViz/bin'
Then put the model to plot

clf = xgb.train(params, d_train, 1000, evals=evallist, early_stopping_rounds=10) xgb.plot_tree(clf) plt.rcParams['figure.figsize'] = [50, 10] plt.show()

Solution 17 - Python

I had the same issue on Linux with Jupyter.

To solve it I've added the dot library to python sys.path

First: check if dot is installed,

Then:
find his path whereis dot -> /local/notebook/miniconda2/envs/ik2/bin/dot

Finally in python script : sys.path.append("/local/notebook/miniconda2/envs/ik2/bin/dot")

Solution 18 - Python

After you've installed the package (link if you haven't), add the path to dot.exe as a new system variable.

Default path is: > C:\Program Files (x86)\Graphviz2.38\bin\dot.exe

Solution 19 - Python

1- first downlaod it(graphviz 2.38).

2- install org.graphviz.Graphviz-2.38-graphviz-2.38.

3- now add "C:\Program Files (x86)\Graphviz2.38\bin" and "C:\Program Files (x86)\Graphviz2.38\bin\dot.exe" to path like this video
note:in windows 8 you must use ; for path example: C:\Program Files;D:\Users;E:\file\

Solution 20 - Python

In Windows environment, use chocolately to install, it will ensure the environmental vars are set correctly.

choco install graphviz

Solution 21 - Python

First, you should use pip install, and then download another package in http://www.graphviz.org/Download_windows.php and add the install location into the environmental path, then it works.

Solution 22 - Python

I had the same error message on Mac OS (El Capitan), using the PyCharm IDE. I had installed Graphviz using brew, as recommended in RZK's answer, and installed the graphviz python package using PyCharm (I could check Graphviz was installed correctly by trying dot -V in a terminal and getting: dot - graphviz version 2.40.1 (20161225.0304)). Yet I was still getting the error message when trying to call Graphviz from PyCharm.

I had to add the path /usr/local/bin in PyCharm options, as recommended in the answer to this question to resolve the problem.

Solution 23 - Python

Add graphviz to the System Path

Windows - Edit the System Environment Variables.
Choose Environment Variables.
Select Path - New
Add the Path of graphviz

Ex: C:\Users\AppData\Local\Continuum\anaconda3\Library\bin\graphviz

Solution 24 - Python

try typing the following code in anaconda prompt one by one.

this worked for me.

Source: https://anaconda.org/conda-forge/python-graphviz

conda install -c conda-forge python-graphviz
conda install -c conda-forge/label/broken python-graphviz
conda install -c conda-forge/label/cf201901 python-graphviz
conda install -c conda-forge/label/cf202003 python-graphviz

Restart the kernel afterwards!

Solution 25 - Python

For Linux users who don't have root access and hence can't use sudo command as suggested in other answers...

First, activate your conda virtual-environment (if you want to use one) by:

source activate virtual-env-name

Then install graphviz, even if you have already done it using pip:

conda install graphviz

then copy the result of the following command:

whereis dot

In my case, its output is:

/home/nader/anaconda2/bin/dot

and add it to your PATH variable. Just run the command below

nano ~/.bashrc

and add these lines to the end of the opened file:

PATH="/home/username/anaconda2/bin/dot:$PATH"
export PATH

now press Ctrl+O and then Ctrl+X to save and exit.

Problem should be solved by now.

Pycharm users, please note: Pycharm does not always see the PATH variable the same as your terminal. This solution does not work for Pycharm, and maybe other IDEs. But you can fix this by adding this line of code:

os.environ["PATH"] += os.pathsep + '/home/nader/anaconda2/bin'

to your python program. Do not forget to

import os

first :)

Edit: If you don't want to use conda, you can still install graphviz from here without any root permissions and add the bin folder to your PATH variable. I didn't test this.

Solution 26 - Python

1.install windows package from: https://graphviz.gitlab.io/_pages/Download/Download_windows.html and download msi file

Add in Environmental variables 2. Add C:\Program Files (x86)\Graphviz2.38\bin to User path

Add C:\Program Files (x86)\Graphviz2.38\bin\dot.exe to System Path
Restart your python notebook.

It will work.

Solution 27 - Python

OS Mojave 10.14., Python 3.6

Using pip install graphviz had good feedback in terminal, but lead to this error when I tried to make a graph in a Jupyter notebook. I then ran brew install graphviz, which gave an error in terminal. Then I ran conda install graphviz and the graph worked.

From @Leighton's comment: pip only gets path problem same as yours and conda only gets import error.

Solution 28 - Python

#Write this on anaconda prompt in admin mode
conda install -c anaconda graphviz
conda install -c conda-forge python-graphviz
conda install -c conda-forge/label/broken python-graphviz
conda install -c conda-forge/label/cf201901 python-graphviz
conda install -c conda-forge/label/cf202003 python-graphviz

#check dot -v in window's cmd prompt
C:\WINDOWS\system32>dot -V
dot - graphviz version 2.38.0 (20140413.2041)
(this means graphviz installed successfully)

#Add path to sys and user eve variables
PATH
C:\Anaconda3\pkgs\graphviz-2.38-hfd603c8_2\Library\bin
(search bin folder of graphviz and then copy n paste path in env variables)

#Re-run all cmds in jyupter notebook
#if error occurs (less chances)
#then 
#Restart anaconda and again run all cmds in jyupter notebook
eg.
import graphviz as gp
with open("tree.dot") as f:
    dot_read=f.read()
display(gp.Source(dot_read))

Solution 29 - Python

I am using windows10 , I tried installing graphwiz in program files and setting the path: Didn't worked for me

Tried

conda install -c anaconda graphviz

doesn't work.

Then tried

conda install python-graphviz

It worked, It seems our python compiler is not able to access the Graphwiz. Hence python-graphwize worked. pip install graphviz also didn't work.

Solution 30 - Python

When I first installed pydot and graphviz it showed me the error, but the command below worked for me:

import os
os.environ["PATH"] += os.pathsep + r'C:\Users\vivek\Downloads\graphviz-2.44.1-win32\Graphviz\bin'

Solution 31 - Python

import os
os.environ["PATH"] += os.pathsep + "/Macintosh HD⁩/anaconda3⁩/lib⁩/⁨python3.7⁩/site-packages⁩/sphinx⁩/templates⁩/graphviz"

This solved the PATH issue on MAC for me!

Solution 32 - Python

If you are not using Conda but vanilla Python, 'brew install graphviz' works.

Solution 33 - Python

Mac & Big Sur. Python 3.8.6 w/vs code. While it should have been included in diagrams package, I had to manually install graphviz.

(mymltools) ➜  infrastructure git:(master) pip list
Package    Version
---------- -------
diagrams   0.18.0
graphviz   0.13.2
Jinja2     2.11.2
MarkupSafe 1.1.1
pip        20.3.2
setuptools 51.0.0
wheel      0.36.2

Running diagrams failed. Then manually ran

pipenv install graphviz

Works like a charm.

Solution 34 - Python

MACOS - Solution for Monterey

Open: Terminal
Run: pip install graphviz
Run: brew install graphviz
Close: Terminal
Open: Anaconda (Jupyter or Spyder)
Run: import os
os.environ["PATH"] += os.pathsep + "/usr/local/Cellar/graphviz/2.49.3/bin/dot"

(You'll have to run this EACH time until the bug is fixed.) The tricky part is finding the dot file. It is the location where brew installs the package. (But it should be something similar to the path that I gave.) Test by running:

import mglearn as mglearn
mglearn.plots.plot_animal_tree()

Hopefully, you are good to go now!

Solution 35 - Python

you can use the following command in Anaconda prompt :

> conda install python-graphviz

and make sure to install pm4py in Anaconda prompt : > pip install pm4py

and in the end you have to try running your python code with Anaconda propmpt.

Solution 36 - Python

trying doing this in python import sys !conda install --yes --prefix {sys.prefix} graphviz import graphviz
