ImportError: No module named manalytics.M_Analytics.Analytics_Manager.Analytics_Process.ReadUnread_AP.ReadUnread_AP

Im using python3.6 in local and python2.7 in server. Im trying to import the a module using importlib.import_module() function. importlib.import_module() function is called in 'Analytics_Process.py'

In local machine its directory structure of my project is

 M_Analytics->
     __init__.py
     Analytics_Manager
        ->
          __init__.py
           Analytics_Manager.py
          Analytics_Process
           ->
            __init__.py
            Analytics_Process.py
            ReadUnread_AP
            ->
             __init__.py
             ReadUnread_AP.py

and in local it is working fine with

importlib.import_module('M_Analytics.Analytics_Manager.Analytics_Process.ReadUnread_AP.ReadUnread_AP')

manalytics
   __init__.py ,
   M_Analytics
   ->
     __init__.py,
     Analytics_Manager
        ->
          __init__.py,
           Analytics_Manager.py
          Analytics_Process
           ->
            __init__.py,
            Analytics_Process.py
            ReadUnread_AP
            ->
             __init__.py
             ReadUnread_AP.py

and in server it is giving error for importlib.import_module('manalytics.M_Analytics.Analytics_Manager.Analytics_Process.ReadUnread_AP.ReadUnread_AP')

directory path in server:
