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

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

sudo apt-get install graphviz

---

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.

---

This one should solve the problem on MAC:

  brew install graphviz

---

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!

---

Try using:

conda install python-graphviz

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

---

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

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.

---

This is showing some path issue:

pip install graphviz

So this worked for me:

sudo apt-get install graphviz

---

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

---

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.

---

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

---

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.

---

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).

---

conda install python-graphviz

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

---

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.

---

1) 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'

2) 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()

---

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")

---

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

---

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\

---

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

choco install graphviz

---

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.

---

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.

---

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

---

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!

---

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.

---

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.

---

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.

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.

#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))

---

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'
