I'm not sure I understand what this concept is. What do you mean by
“top-level module”?

That looks okay. Does it work?
The code is readable and Pythonic as is. But I would suggest several
improvements::
if getattr(sys, "frozen"): # ‘getattr’ will return None by default
Also, why test for “sys.frozen” when you're about to use
“sys.executable”?
if getattr(sys, "executable"):
Lastly, it's slightly more Pythonic to execute the normal path
unconditionally, and let it raise an exception if there's a problem::
try:
executable = sys.executable
except AttributeError:
executable = __file__
path = os.path.dirname(executable)
