Multilevel relative import
I have following folder structure
top\
__init__.py
util\
__init__.py
utiltest.py
foo\
__init__.py
foo.py
bar\
__init__.py
foobar.py
I want to access from foobar.py
the module utiltest.py
. I tried following relative import, but this doesn't work:
from ...util.utiltest import *
I always get
ValueError: Attempted relative import beyond toplevel package
How to do such a multileve relative import?

I realize this is an old question, but I feel the accepted answer likely misses the main issue with the questioner's code. It's not wrong, strictly speaking, but it gives a suggestion that only coincidentally happens to work around the real issue.
That real issue is that the
foobar.py
file intop\foo\bar
is being run as a script. When a (correct!) relative import is attempted, it fails because the Python interpreter doesn't understand the package structure.The best fix for this is to run
foobar.py
not by filename, but instead to use the-m
flag to the interpreter to tell it to run thetop.foo.bar.foobar
module. This way Python will know the main module it's loading is in a package, and it will know exactly where the relative import is referring.
