As the name sys is used in the imported module, that module has to import sys.
Importing it in the calling code doesn't help.
So I would say this is a bug in the module.

You should report the bug to its author. In the meantime you can correct your own copy at
~/opt/miniconda3/envs/py3/lib/python3.6/site-packages/ipyrad/analysis/treemix.py
by adding
import sys
for example around line 10
