Hi,
release 0.4 is not fully compatible with python 3.
If you check the commits you can see there is some work currently ongoing:
https://github.com/datacenter/acitoolkit/commits/master
you can try installing acitoolkit directly from github master branch and see if it already resolves your issues:
i.e.
pip install https://github.com/datacenter/acitoolkit/archive/master.zip
Note that this will still be visible as version 0.4.
If it doesn't resolve your problems, please submit an issue (ideally with a minimal script to reproduce) to github.
