Comment out:
i) from keras.utils import plot_model
and
ii) line 366 where it plots the model

thank you! it seems now i got another error for a different line.
for the line: dae.train(train_mains, train_meter, epochs=25, sample_period=1)
i get the error: ValueError: NaTType does not support dst

I tried to replicate the result and stuck at this stage as well. I imported daedisaggregator.py using %load daedisaggregator.py
Even I had installed pydot but the error on installation came out. The commenting out of the 2 lines was also done.
ImportError: Failed to import pydot. Please install pydot. For example with pip install pydot`
Please help, thanks.

Usually, installing GraphViz means

sudo apt-get install graphvis

in Ubuntu/Debian or the equivalent command in other operating systems.

As for pydot you can also discuss here #8
