Locust: No module named 'core' error

[CakeEddy]

I saw that there was an issue with this earlier but it was closed (back in Oct 2016). But I'm seeing the exact same thing.
I'm running Mint (ubuntu) and I'm seeing the "No module named 'core'" issue.

I installed locust via pip install which installs locust into the /usr/local/lib/python3.5/dist-packages/locust/ directory.

Any help would be greatly appreciated.

Seems that installing locust with this command fixed the issue for me...

sudo pip install -e git://github.com/locustio/locust.git@master#egg=locustio
