Из-за чего ошибка и как исправить?

from tkinter import *
from tkinter import PhotoImage

root=Tk()
root.geometry('141x124')
root.resizable(0, 0)

our_image= PhotoImage(file= "1.png")
our_label= Label(root)
our_label.image=our_image
our_label['image']=our_label.image
our_label.place(x=0, y=0)

root.mainloop()

Вот ошибка:
