From the comments:

There may have been two problems:

• The path to myapplication/ not added to the $PYTHONPATH environment variable (more here and here ) Let's say the code lives under /home/peg/myapplication/ . You need to enter your terminal export PYTHONPATH=${PYTHONPATH}:/home/peg/myapplication/

• __init__.py could be a typo. There should be no spaces between the __ underscores and the init.py node ( __init__.py good, __ init __.py n’t)
