Not at all! This is a personal bias - I happen to have been using Pytest.

Your objective is learning to program in Python. 'Chopping and changing' 
between ancillary tools would be a distraction and time-sink. If you 
have already started learning unittest, keep going.

We all have to start 'somewhere'! At the learning stage, any one of 
these tools will help you with testing, and testing should improve your 
overall programming skills. Once your expertise, in both Python and the 
testing tool, matures; you will be better placed to survey the 
opportunities and to choose the best alternative for you and your 
applications...
