ImportError: Failed to import `pydot

When I open run.ipynb in jupiter, in block 2 (In: 2) I have a message:

---

ImportError Traceback (most recent call last)

Reinstalling keras and pydot on the required versions does not solve the problem

I had a similar issue, had to install pydot-ng as well, did you installed everything using the requirements file ?

[Vovak1919]

No, I just commented out the line with the code:
plot_model(current_NN.model, to_file=run_folder + 'models/model.png', show_shapes = True)

This helps

import os
os.environ["PATH"] += os.pathsep + 'C:/Program Files (x86)/Graphviz2.38/bin/'

I resolved this error(in docker container) with the following commands:

apt-get update
apt-get install python-pydot python-pydot-ng graphviz
pip install --upgrade pip
pip install pydot graphviz 

Hope this help.
