Plain 'python' on Ubuntu usually runs Python v2.
It looks like you don;t have Matplotlib inastalled for Python 2.
Matplotlib is part of the 3rd party SciPy libraries and not
part of the standard python install.
Having looked at the web page it seems you need to use python3
and have scipy, numpy and matplotlib packages installed.
You should have them in your software centre as
python3-scipy, python3-numpy and python3-matplotlib

That's correct. But without seeing the code and data it's
hard to guess but you could at least verify that it runs
by editing the python file to include print lines.
Go to the end of the file and modify the last segment
to look like:
if __name__ == "__main__":
print("Starting....")
main()
print("Stopping...")

I see the code but I don't see a path that
doesn't print anything... You should see some
kind of output.
