（“AttributeError:“PhotoImage”对象没有属性“\u PhotoImage\u photo”）[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()

上面是一段代码，用于在python中创建注册表单并获得以下错误。在python中使用tkinter模块，我正在创建注册表单，这意味着当我在窗口self.bg = ImageTk.PhotoImage(file="Images/waterfall.jpg")中设置背景图像并出错时，我从联机获取图像，并将其设置为高度和宽度

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__
    self.bg = ImageTk.PhotoImage(file="Images/waterfall.jpg")

    image = _get_image_from_kw(kw)

Answer 1

我不使用这个

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，请仔细检查瀑布.jpg所在的文件
