ImportError: You must install pydot and graphviz for `pydotprint` to work.

[bukosabino]

When I run capsulenet.py, I have this error:

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

But, I have installed pydot and graphviz: pydot==1.2.3 graphviz==0.8.1

Any idea?

Solved. I commented the plot_model line.

Thanks you. Good code @XifengGuo

hi @bukosabino, can you tell me what you commented out to get the plot_model to work?

[bukosabino]

hi @brownpanther ,

I think my reply doesn't make sense now because this line is out of current code.

hi @bukosabino, can you tell me what you commented out to get the plot_model to work?

I got this to work by "brew install graphviz".

[ReneWu1117]

sudo apt-get install graphviz

[pcko1]

pip install graphviz within my conda env solved it for me

p.s. I also tried conda install graphviz but problem persisted

This fixed it for me on my Mac.

Just in case someone using windows might need it, modify the pydot.py file. It should be in <python_install_path>\Lib\Site-packages\pydot.py. Besides pip install pydot and pip install graphviz, also install graphviz software. And add the software bin directory to the system's path. And in class Dot(Graph), change self.prog = 'dot' to self.prog = 'dot.exe'

Seems that the package was written for *nix system. So in windows, assign it to be an .exe file.

I was able to get it to work with Tensorflow 2 on Ubuntu with:

pip install pydot
pip install pydotplus
apt-get install graphviz
pip install graphviz

@swun90 Thank you for your solution. It works for me :)

Also I needed to open CMD with administrator privileges and run dot -c or dot.exe -c.

Install pydot, graphviz using conda/pip Add a couple of changes in <python_install_path>\Lib\Site-packages\pydot.py as below:

def get_executable_extension():
    # type: () -> str
    if is_windows():
        #return '.bat' if is_anacoda() else '.exe'
        return '.exe'
    else:
        return ''

return.bat didn't exist in Graphviz install directory.

class Dot(Graph):
    """A container for handling a dot language file.

    This class implements methods to write and process
    a dot language file. It is a derived class of
    the base class 'Graph'.
    """

    def __init__(self, *argsl, **argsd):
        Graph.__init__(self, *argsl, **argsd)

        self.shape_files = list()
        self.formats = [
            'canon', 'cmap', 'cmapx',
            'cmapx_np', 'dia', 'dot',
            'fig', 'gd', 'gd2', 'gif',
            'hpgl', 'imap', 'imap_np', 'ismap',
            'jpe', 'jpeg', 'jpg', 'mif',
            'mp', 'pcl', 'pdf', 'pic', 'plain',
            'plain-ext', 'png', 'ps', 'ps2',
            'svg', 'svgz', 'vml', 'vmlz',
            'vrml', 'vtx', 'wbmp', 'xdot', 'xlib']

        #self.prog = 'dot' # Unix
        self.prog = r'C:\Program Files\Graphviz\bin\dot' # Windows absolute path

For some reason subprocess.Popen was not able to find 'dot.exe' from my system (I had Graphviz/bin to the system path variables), used absolute path instead and it worked!
