AttributeError: module 'pydot' has no attribute 'find_graphviz'

[ghost]

My os is Ubuntu 14.04 and python version is 3.5. I just simply did what the document said:

from keras.utils.visualize_util import plot

And what I got is:

   ---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

AttributeError: module 'pydot' has no attribute 'find_graphviz'

Indeed I have ensured that pydot, pydotplus, graphviz have been installed as I could import them properly. Do you know how to fix it? Thank you in advance!

[tboquet]

You can try to install pydot-ng.

[ghost]

@tboquet Thanks for your help! But this time I got this error: RuntimeError: Failed to import pydot. You must install pydot and graphviz forpydotprintto work. But I have installed pydot and graphviz already. Do you have any idea about that?

[oeway]

Here is how I fix the problem:
sudo pip install pydot==1.0.2 --upgrade
It seems pydot don't provide a function named find_graphviz anymore.

[ghost]

@oeway The same error still exists....

[oeway]

Could you try to install from here: https://github.com/nlhepler/pydot

As you can see from here https://github.com/nlhepler/pydot/blob/master/pydot/__init__.py#L474 , they do have find_graphviz function.

[litstrong]

@rylanchiu
I had same problem like you had.

I think it is caused by could not find the graphviz although graphviz is installed.

When I use brew install graphviz, there was a warning said not linked.

It works and linked successful after I tried to uninstall it and re-install. Or you can try brew link ?

[hadim]

Would it be possible to add support for pydotplus since it's available in conda-forge for python 3.5 while pydot is not available with conda ?

[nouiz]

The problem is that pydot changed a small part of its interface. We fixed
that in Theano in this commit:

Theano/Theano@aefd29d

It would be easy to do the same in keras to suport its newer version.

pydot-ng will give you pydot that satisfies the keras package, use
pip install pydot-ng
to install it in your virtualenv.

On ubuntu you need to have the "dot" executable in your PATH, you can do this by installing the graphviz package:
apt-get install graphviz

[zhourunlai]

First, the pydot will find_graphviz, in line 7 of visualize_util.py.
Then, it will check these PATH to judge whether the graphviz exists, in line 605 of pydot_ng/__init__.py.

'/usr/bin', '/usr/local/bin',
            '/opt/local/bin',
            '/opt/bin', '/sw/bin', '/usr/share',
            '/Applications/Graphviz.app/Contents/MacOS/'

So, we should install graphviz by these way:

1. download APP, this will put to /Applications/Graphviz.app/Contents/MacOS/;
2. command brew install graphviz, this will create the link to /usr/local/bin.

pydot pre 1.2.0 do not support python 3...

[dotasheepliu]

I can run it after installing everything mentioned above.

[manashmandal]

I faced similar problem and executing the following commands solved my problem.

pip install pydot-ng
sudo apt-get install graphviz

[Ellenisawake]

Same issue here...
Seems that pydot-ng supports up to Python 3.4?
And pydot 1.1.0 not available in conda...
For Keras to work properly with Python 3.5, any consideration to embed pydotplus?

http://stackoverflow.com/questions/36869258/how-to-use-graphviz-with-anaconda-spyder

Downloading Graphviz from their website (msi version in my case given I'm on windows) and adding
C:\Program Files (x86)\Graphviz2.38\bin to my system variables in PATH worked for me.

[sookinoby]

Thanks @Tahsin-Mayeesha . This is the right solution.

[CreatCodeBuild]

I tried install all the requirement both from pip and from binary installation on system and I configured my PATH. It doesn't work.
I am using Windows 10, Python 3.5.2 |Anaconda 4.0.0 (64-bit)| (default, Jul 5 2016, 11:41:13) [MSC v.1900 64 bit (AMD64)] on win32

Regardless, how useful is this visualization?
Is there any third-party library I can use?

[sookinoby]

What is the error you getting? I
Visualization is not very useful - sample - https://github.com/sookinoby/behavior-cloning/blob/master/images/model.png
I edited the image to wrap around.

model.summary() is more useful.
I don't know any third party library. `

I can import pydot, graphviz.
I can also use dot at Terminal.

install - http://www.graphviz.org/Download_windows.php. Add the bin folder to windows path. Everything will work fine.

[naotokui]

on Mac, the following commands fixed the issue:

sudo pip install pydot-ng
brew install graphviz

[tomas-angles]

On Mac: If you are working in a virtual environment with Anaconda (always do that to avoid messing up the python in your OS):

1. source activate virtualenv_name
2. conda install graphviz
3. pip install pydot-ng

And run your script from terminal. As a sanity check (in terminal):

1. python
2. import pydot_ng as pydot
3. pydot.find_graphviz()

The output should be a string similar to: "{'dot': 'your_path/bin/dot', 'twopi': ..."

But, @sookinoby is right, model.summary() is much more useful.

[tboggs]

I have this issue with python3 on ubuntu 16.04. Since I know I have the necessary packages installed, I do the following to avoid the error:

import pydot
pydot.find_graphviz = lambda: True

[jemshit]

For Mac, we need brew install graphviz besides pip install graphviz

[enduringstack]

try pydotplus

[diyali03]

I have this issue with ubuntu 16.04
But raises import error:

ImportError('Failed to import pydot. You must install pydot'
ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work.

This can help me

pip install pydot-ng
sudo apt-get install graphviz

[DerekGrant]

For window, this because python can't find graphviz path, in pydot_ng init.py
It just search path for linux and Mac user, will can fix this problem by add path

for path in (
            '/usr/bin', '/usr/local/bin',
            '/opt/local/bin',
            '/opt/bin', '/sw/bin', '/usr/share',
            '/Applications/Graphviz.app/Contents/MacOS/'
            ):
        progs = __find_executables(path)
        if progs is not None:
            print("Used path")
            return progs

We should modify to

    for path in (
            '/usr/bin', '/usr/local/bin',
            '/opt/local/bin',
            '/opt/bin', '/sw/bin', '/usr/share',
            '/Applications/Graphviz.app/Contents/MacOS/'
            ):
        myGraphVizPath='D:\\Programming\\Graphviz2.38\\bin'#my graphviz path 
        progs = __find_executables(myGraphVizPath)
        if progs is not None:
            print("Used path")
            return progs

    # Failed to find GraphViz
    return None

[tharuniitk]

HI @tomas-angles :
I followed the procedure given in your comments for installing pydot, graphviz. Every thing works fine as far as sanity check is concerned(in terminal):

python
import pydot_ng as pydot
pydot.find_graphviz()

import pydot_ng
pydot_ng.find_graphviz()
{'twopi': '/usr/bin/twopi', 'fdp': '/usr/bin/fdp', 'circo': '/usr/bin/circo', 'neato': '/usr/bin/neato', 'dot': '/usr/bin/dot', 'sfdp': '/usr/bin/sfdp'}

But the following lines of code in python script run under keras leaves an error below again and again:

from keras.utils import plot_model
plot_model(model1, to_file='model.png')

plot_model(model1, to_file='model.png')
File "/home/tharun/anaconda2/envs/kerasdl/lib/python2.7/site-packages/keras/utils/vis_utils.py", line 132, in plot_model
dot = model_to_dot(model, show_shapes, show_layer_names, rankdir)
File "/home/tharun/anaconda2/envs/kerasdl/lib/python2.7/site-packages/keras/utils/vis_utils.py", line 52, in model_to_dot
_check_pydot()
File "/home/tharun/anaconda2/envs/kerasdl/lib/python2.7/site-packages/keras/utils/vis_utils.py", line 27, in _check_pydot

Please see #5313 (comment) and #3216 (comment).

Comments about installation: https://stackoverflow.com/a/47209738/1959808
(GraphViz is needed; the Python package graphviz is unrelated to pydot).

[pyaf]

pip install pydot-ng
conda install graphviz

[stajilov]

On macOS:
pip3 install pydot-ng
brew install graphviz

[johnyf]

This issue has been addressed by #6398, specifically 54a417f. It can be closed.
Currently, there is no line in keras that calls the nonexistent find_graphviz:

keras/keras/utils/vis_utils.py

Lines 23 to 32 in e73199d

	def _check_pydot():
	try:
	# Attempt to create an image of a blank graph
	# to check the pydot/graphviz installation.
	pydot.Dot.create(pydot.Dot())
	except Exception:
	# pydot raises a generic Exception here,
	# so no specific class can be caught.
	raise ImportError('Failed to import pydot. You must install pydot'
	' and graphviz for `pydotprint` to work.')

[charusanmathi]

I had the same error on my MacBook and I installed pydot on Jupyter notebook

! pip install pydot

But grraphviz wouldn't work, so I went to graphviz documentations and installed home-brew on my terminal and then
used the following command

brew install graphviz

This worked well and I could see the plot
