Thanks @Suteja Kanuri​ for your answer. Indeed I'm aware of the GUI situation. In fact, I have no intention of using the GUI feature, however, tkinter is imported on a module level. Even if I'm not calling Tkinter code at all, since the import is in the same file as other code that I'm calling, then it's gonna raise an exception.

so, the question is.. is there a way to install Tkinter when I'm not planning to use it?
