Tkinter和PIL映像在__init__之外不起作用

Question

我正在使用tkinter和PIL在GUI上显示一些图像当我在__init__函数中打开图像时，在self外部使用它可以工作，但是当我在函数内部打开图像并在同一函数中使用时尽管图像在文件夹中，但基本上不会出现任何错误的图像。 这是代码

import datetime 
import time
import os
from tkinter import *

    import tkinter

    from PIL import Image, ImageTk
    from json_helper import JSONHelper
    from babel.dates import format_date, format_datetime, format_time

        class GUI():
        def __init__(self, configs, settings):
                self.configs=configs
                self.settings=settings
                self.root =  Tk()
                #self.root.attributes('-fullscreen', True)
                self.canvas = Canvas(self.root, width=480, height=800)
                self.canvas.pack()

        def _days(self, x, y, anc, visibility):
                day_list= ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"] 

                for day_item in day_list:
                    response_days = self.settings.Weather.Days

                    #These are from config file. So you can print 7 of them.
                    day_name = getattr(self.configs.Gui.Weather.Days, day_item) # pzt,sali,cars
                    self.canvas.create_text(x, y, fill= "white", font = "Corbel 16",   anchor = anc, state= NORMAL, text = day_name)

                    for response_day in response_days:
                        if response_day.Day == day_item:

                            weather_image = getattr(self.configs.Gui.Weather.Images, response_day.Text)

                            opened_image = Image.open(self.configs.Folders.Gui + str(weather_image.Small))
                            image1 = ImageTk.PhotoImage(opened_image)
                            print(self.configs.Folders.Gui + str(weather_image.Small))

                            self.border(self.canvas.create_image(x, y+30, image=self.image_sunny_small, anchor=anc ,state=NORMAL))
                            self.canvas.create_text(x, y+60, fill= "white", font = "Corbel 16",   anchor = anc, state= NORMAL, text = response_day.Degree)

                    x+=62

这是文件夹

~/Desktop/hodor/src/images/gui $ ls
