I have installed correct libraries and version, after deploying its working on my local environment but not showing error on deployed url

Hey,

It appears that you are attempting to install https://docs.python.org/3/library/tkinter.html, which relies on OS-level dependencies. However, please note that even if you were able to install this library, it would not be usable on Render since we do not support exposing a graphical user interface (GUI).

Regards.
Jérémy, Render Support
