I ran it locally, for me it chokes with:

| autopkgtest [18:58:22]: test command1: xvfb-run --auto-servernum --server-num=20 -s "-screen 0 1024x768x24 -ac +extension GLX +render -noreset" sh debian/tests/run-unit-test

On checking, it stems from the fact that fury (python module) that dipy needs is not in (test-)depends, and neither is it in the
archive.
Probably other tests also are missing some or the other module. I also see a couple of circular imports that we need to fix.

This is my understanding ^^ so maybe packaging fury will help.
