How to use the pyinstaller.buildtests.import.relimp.relimp.relimp2.__name__ function in pyinstaller

from __future__ import absolute_import

name = 'relimp.relimp1'

from . import relimp2 as upper
from . relimp import relimp2 as lower

assert upper.name == 'relimp.relimp2'
assert lower.name == 'relimp.relimp.relimp2'

if upper.__name__ == lower.__name__:
    raise SystemExit("Imported the same module")

if upper.__file__ == lower.__file__:
    raise SystemExit("Imported the same file")
