What error this is fixing? Which version of nose do you use?

$ pip freeze | rg nose
nose==1.3.7
nose-parameterized==0.5.0

don't have the error handy but without this import I could not run the command DEVICE=cuda0 python -c "import pygpu; pygpu.test()"

This will fix the immediate problem, but there is the alternative problem that it triggers a flake8 warning.

#459 fixes the problem and avoids a flake8 warning.

This was addressed in #459 which was merged, but thanks for the fix.
