error, during using iconbitmap tkinter.TclError: bitmap "image\inventory.ico" not defined
iconbitmap is to set the icon of the application you can set the title by root.title("window_name")And if you show your code then it would be easy to tell the problem.
Hard to tell what the exact problem is without seeing your code. From personal experience I had a similar error message when I used Frame() instead of LabelFrame().
