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

问题

I have seen similar issue but it is not solved either, so I decided to ask.

I am trying to visualize my model in keras using

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

First, it showed error

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

Accordingly, I installed pydot and graphviz through Anaconda prompt activating my environment using

conda install -c https://conda.binstar.org/t/TOKEN/j14r pydot
conda install -c https://conda.binstar.org/t/TOKEN/j14r graphviz

Then, I closed spyder and reopened it. When I run code snippet, it is still showing the same error. What am I missing?

回答1:

Use next command to install them:

sudo apt install python-pydot python-pydot-ng graphviz

回答2:

The following commands solved the problem for me

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

回答3:

These commands work for me. I did:

conda install -c https://conda.binstar.org/t/TOKEN/j14r pydot
conda install -c https://conda.binstar.org/t/TOKEN/j14r graphviz
sudo apt install python-pydot python-pydot-ng graphviz

回答4:

For me, all I had to do was install graphviz and pydot:

On Python3:

pip3 install pydot-ng
pip3 install graphviz

On Python2:

pip3 install pydot-ng
pip3 install graphviz

That resolved the error for me.

回答5:

Restarting the Kernel solved the problem for me, without needing pydot-ng.

回答6:

Solution found from: https://github.com/XifengGuo/CapsNet-Keras/issues/69#issuecomment-483273641

I followed the advice of uninstalling and reinstalling pydot + pydotplus and that successfully solved the issue on my Windows 10 machine using Anaconda 3.

conda uninstall pydot
conda uninstall pydotplus
conda uninstall graphviz

then

conda install pydot
conda install pydotplus

Note: installing pydot also installed graphviz

import tensorflow as tf
tf.keras.utils.plot_model(
    model,
    to_file='model.png',
    show_shapes=False,
    show_layer_names=True,
    rankdir='TB',
    expand_nested=False,
    dpi=96
)
