("AttributeError：'PhotoImage‘对象没有'_PhotoImage__photo’属性) [Tkinter]

Question

代码：

from tkinter import*
from PIL import Image,ImageTk

class Register:
    def __init__(self,root):
        self.root = root
        self.root.title("Registration Window")
        self.root.geometry("1350x700+0+0")

        self.bg = ImageTk.PhotoImage(file="Images/waterfall.jpg")
        bg = Label(self.root,image = self.bg).place(x=250,y=0,relwidth=1,relheight=1)

root = Tk()*emphasized text*
obj = Register(root)
root.mainloop()

上面是一小段代码，用于在python中创建注册表单，并得到以下错误。使用python中的tkinter模块，我创建了注册表，而当我在window self.bg = ImageTk.PhotoImage(file="Images/waterfall.jpg")中设置背景图像和错误提升时，我从网上获取图像，并设置其高度和宽度。

错误：

Traceback (most recent call last):
  File "d:\Login with Database\register.py", line 16, in <module>
    obj = Register(root)
  File "d:\Login with Database\register.py", line 10, in __init__

Answer 1

我是客人，而不是用这个。

self.bg = ImageTk.PhotoImage(file="Images/waterfall.jpg")
bg = Label(self.root,image = self.bg).place(x=250,y=0,relwidth=1,relheight=1)

试试这个。

self.bg=ImageTk.PhotoImage(file="Images/waterfall.jpg")
self.bg_image=Label(self.root, image=self.bg).place(x=0, y=0, relwidth=1, relheight=1)

另外，仔细检查waterfall.jpg所在的文件。
