Python app engine non-standard package import -

i need non-standard app engine package named qrcode. pure python lib depends on pil, supported app engine.

my folder structure is:

app |--- handlers/ |------ my_handler.py |--- util/ |------ __init__.py |------ qrcode/ |--------- __init__.py |--------- qrcode/ |------------ __init__.py |------------ other lib files |--- index.py 

on index.py map my_handler.py , on my_handler.py call from util.qrcode import qrcode inside 1 of handler classes' method. problem importerror: no module named qrcode.main on __init__.py file.

__init__.py:

from qrcode.main import qrcode, make qrcode.constants import * qrcode import image 

qrcode.main 1 .py file inside qrcode package (to see whole package, check repository linked here)

i looked , can't find wrong. i'd appreciate help. thanks!

the python path include directory app.yaml lives. if that's app module lives, should use absolute imports:

# in index.py app.handlers import my_handler  # in my_handler.py app.util.qrcode import qrcode
