Hi! Found this issue when trying to build:

Let me know if there's anything I can do to help you debug this!

DoodleMaster is a really great job! I love it. And I want to try it by myself, but I don't know how to run. My python knowledge is not good yet. If you can post a how-to-build readme, it'll be very helpful. Thanks!

What's up with div method in layout.py ?

def div(margin_top,h,w):
    hv

Method isn't used anywhere. hv is unresolved.

Can the whole layout.py be removed? I don't see it being used in any other module.

Hello! I created a virtualenv with python 3.6 using the next command: mkvirtualenv --python=/usr/local/Cellar/python3/3.6.2/bin/python3 DoodleMaster -r requirements.txt

Everything was right during the installation, but not at the moment of the execution: python server.py

After that, I reinstall numpy 1.13.3 (as required in the requirements file) using pipenv:

I found (here)[https://stackoverflow.com/a/52717947/1674908] that a possible solution was to upgrade numpy to 1.15.2:

pipenv install numpy==1.15.2

The numpy upper version solves my problem.
