Attempted relative imports to non-batch

My project has the following structure:

+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.pyboth depend on user_operations, and when I try to call them, I get an error relative import in non-package.

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)

Module called 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

ValueError: Attempted relative import in non-package

Does anyone know how I can save my file structure and include modules under modulesto use modules under common?
