AttributeError: module 'cardio.dataset' has no attribute 'Batch'

I got this while trying to follow the tutorial:

import cardio.dataset as ds

Here are the install steps I used - I had to manually install numba after getting an error about it being missing:

cd cardio
virtualenv --python=python3 venv
source venv/bin/activate
pip install .
pip install jupyter
jupyter notebook --port=8089
# I got ImportError: No module named 'numba'
pip install numba

I'm running Python 3.5 on OS X.

Thank you for letting us know.

Did you use the flag --recursive when you cloned the repo?

git clone --recursive https://github.com/analysiscenter/cardio.git

I did not! Will try that later tonight.

Thanks, that fixed the problem I was having. Everything works as expected now.
