Cant Use Tkinter module in setuptools for python2

Question

I have used module for Tkinter in python2 app. But don't know how to put it as install requirements in setup.py. My setup.py file has following modules

install_requires=[
    'pushbullet.py',
    'tweepy',
    'beautifulsoup4',
    'requests',
    'yweather'
],

i want to include Tkinter (python-tk), but I am not able to do so.
