如何在python3.4中修復ImageTk和Tkinter的AttributeError？

Question

這是我寫的代碼，我在其他用戶的幫助下修復了以前的錯誤。但是，這一個殘缺我。這是我的代碼

我在我認爲是問題的地區周圍放置了評論標記。爲了解決這個問題，我已經通讀了一些資料，但沒有發現任何結果。

import tkinter as tk 
import sys 
from timeit import default_timer as timer 
import time 
from PIL import ImageTk, Image 



tot_time=0 
del_time=0 
imgpath=r'logo.jpg' 

def NewTab(): 
    start=timer() 
    time.sleep(del_time) #user defined delay time 
    window.withdraw() 
    win2.deiconify() 
    end=timer() 
    tot_time=end-start 

    labW2.configure(text=('That took %s miliseconds or %s seconds'%(str(round(tot_time*1000,5)),str(round(tot_time,5))))) 

def close(): 
    sys.exit() 

def NTButt(): 
    win2.withdraw() 
    window.deiconify() 


win2=tk.Tk() 
win2.geometry('1100x900') 
win2.title('Button Click') 
labW2=tk.Label(win2, text='ERROR: Time could not be calculated') 
butW2=tk.Button(win2, text='Go back', bg='White', command=NTButt) 
btn2W2=tk.Button(win2, text='Leave', bg='Red', command=close) 
labW2.pack() 
butW2.pack() 
btn2W2.pack() 
win2.withdraw() 



window=tk.Tk() 
window.geometry('1100x900') 
window.title('Hello World') 
lab1= tk.Label(window, text='Input the desired delay time') 
ent=tk.Entry(window) 
btn=tk.Button(window, text='Go to new window', bg='Blue', command=NewTab) 
btn2=tk.Button(window, text='Leave', bg='Red', command=close) 
############################################### 
imgset=ImageTk.PhotoImage(Image.open(imgpath)) 
photo = ImageTk.PhotoImage(imgset) 
labimg = tk.Label(window, image=photo) 
labimg.image = photo 
labimg.pack() 
############################################### 
lab1.pack() 
ent.pack() 
btn.pack() 
btn2.pack() 

window.mainloop() 

虐待包括我收到

錯誤消息我是新來的Tkinter，這可能只是我的一個錯誤，請評論解決方案，幫助我理解。在此先感謝

我不是TKinter專家，但它似乎是提出例外的行： ​​是不需要;您已經在前一行加載了圖像。

因爲你傳遞的ImageTk.PhotoImage()一個實例ImageTk.PhotoImage()

所以異常升高，有問題的代碼位變爲：

############################################### 
photo = ImageTk.PhotoImage(Image.open(imgpath)) 
labimg = tk.Label(window, image=photo) 
labimg.image = photo 
labimg.pack() 
###############################################
