This issue cropped up during the py2->py3 migration and has already been fixed on the master branch, but it is still present in the latest pip package. You can fix your installation by manually patching display.py in your site-packages directory.

As an alternative, you can install the latest master branch

pip uninstall monkeys
git clone https://github.com/hchasestevens/monkeys
cd monkeys
python3 setup.py build

Thanks for the quick response, @klaufira !

Another way to solve that is installing directly from github, with a specific hash.

Consider this issue solved. Thanks! :)
