keras.utils.plot_model keeps telling me to install pydot and graphviz

Question

I tried at least 5 different solutions from numerous posts online but to no avail. This is where I'm at:

In my conda virtual environment, I installed pydot, pydotplus, and graphviz via conda. I went to https://www2.graphviz.org/Packages/stable/windows/10/ and installed both cmake and msbuild and added both /bin folders to User PATH and System PATH variables. I've tried uninstalling and reinstalling packages with conda and with pip yet upon running

keras.utils.plot_model(model, to_file='model_test.png', show_shapes=True, show_layer_names=True)

I still get this error message:

('Failed to import pydot. You must pip install pydot and install graphviz (https://graphviz.gitlab.io/download/), ', 'for pydotprint to work.')

I am able to import pydot and graphviz individually via

import pydot
import graphviz

I'm not entirely sure what's the issue here. Thanks in advance.

Answer 1

On Mac:

pip install pydot 
pip install graphviz 

wasn't sufficient.

I had to do a -

brew install graphviz
