Issue with keras.utils.plot_model -- Issue : You must install graphviz (see instructions at https://graphviz.gitlab.io/download/) for `plot_model` to work.

[debdeepsanyal]

When i was about to execute keras.utils.plot_model() from a snippet in chapter - 07, i got the following error -- You must install graphviz (see instructions at https://graphviz.gitlab.io/download/) for "plot_model" to work.

Now, i have graphviz version 0.20.1 installed. im using keras version 3.0.5 and tensorflow version 2.16.1. and im running the code with a Python 3.12.1 kernel in VS code .ipynb notebook.

Can someone help me with this?

'pip install pydot' is needed.
And don't forget to set environment variable for graphviz.
Try again if it works. I met this problem too when I was reading ch7. I don't remember if more setup steps are needed.

I had the same issue. I based on combining multiple solutions I found on various sites used this to fix it only after restarting kernel the output showed. I'm not sure which of these steps are necessary.

def import_or_install(package):
    try:
        __import__(package)
    except ImportError:
        pip.main(['install', package])

import_or_install("pydot")
import_or_install("pydotplus")
import_or_install("graphviz")

## apt-get install graphviz and restarting kernel worked for me

Edit: fix formatting
Edit2: I'm running this in locally hosted Docker container.
