Attempted relative import in non-package

I have the following structure in my project:

+main_proj

    +modules
        +user_ops
            -add_user.py
            -remove_user.py
            -__init.py
    +common
        -user_operations.py
        -__init__.py
    -main.py
    -__init__.py

My problem is that add_user.py and remove_user.py both depend on user_operations and when I try to call them, I get a relative import in non-package error.

Main.py

from common import user_operations as user_operations  #This works ok

if __name__ == '__main__':

    command = "remove_user"

    #Load usage, functions and paths to modules
    __doc__, function_dictionary, modules = utilities.load_modules()

    #Get function from dictionary
    func = function_dictionary[command]

    #Execute function
    result = func(api_root, arguments, simulate, headers)

The module that gets called by func(api_root, arguments, simulate, headers)

remove_user_front.py

from ...common import user_operations as user_operations

    def remove_user_front(api_root, arguments, simulate, headers):

        #Get users in this account
        users = user_operations.get_users(api_root, arguments["<source_account>"], headers)

        #This is smelly
        if arguments["--id"]:
            type = "id"
        elif arguments["--username"]:
            type = "username"
        #End smell

        result = remove_user(api_root, arguments["<source_account>"], arguments["<user_id>"], type, simulate, headers)

        if not result:
            return False
        else:
            return True

    function_dictionary = {"remove_user" : remove_user_front}

Error:

Traceback (most recent call last):
  File "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensio

    exec(code_obj, global_variables)

    recovery.start_recovery(recovery_file, auto_recovery, headers, modules)
  File "C:\Users\mryan\Documents\Code\cli\recovery.py", line 1

    imported_module = imp.load_source('recovery',module)
  File "C:\Users\mryan\Documents\Code\cli\modules\cam_ops\
remove_user_front.py", line 1, in <module>
    from ...common import user_operations as user_operations
ValueError: Attempted relative import in non-package

Does anybody know how I can keep my file structure and enable modules under modules to use modules under common?

When your application starts up it get's an os.path attributed.

Each modules that will try to import anything will have that same path. It means that your files in common that will need to import something out of user_ops will need to import it like if it was your main.py which would import them.

try

from modules.user_ops import add_user

in your user_operations
