Error in GoogleColab (Python)- TclError: no display name and no $DISPLAY environment variable

Question

有人知道如何修复 GoogleColab Notebook 中 Python 中的以下错误吗？我是运行下面的代码：-

import matplotlib.pyplot as plt

from matplotlib import style
style.use('fivethirtyeight')

import tkinter as tk
from tkinter import filedialog
from tkinter import *
from PIL import ImageTk, Image

import numpy
import keras 
from keras.models import load_model

from sklearn.metrics import accuracy_score

model = load_model('training_model.h5')

classes = { 1: 'Speed Limit 20 km/h',
            2: 'Speed Limit 30 km/h',
            3: 'Speed Limit 50 km/h' }

#initialize GUI

top = tk.Tk()
top.geometry('800x600')
top.title('Traffic Sign Recognition Project Report')
top.configure(background='#EEE')

label=Label(top,background='#CDCDCD', font=('arial',15,'bold'))

sign_image = Label(top)

我在 -> top = tk.Tk()

行收到错误

由于很多原因，无法在 Google Colaboratory 上使用 tkinter。首先，即使您按照 here 设法让它工作，正如它提到的那样：

However, if you want to interact with the GUI, that's going to be hard, 'cuz Colab doesn't support interactive screens out of the box.

也来自那里的其他答案：

Servers generally don't even have a display. And even if they had, you wouldn't see it. You will have to run Python on your desktop or laptop to use tkinter.

我无法将此问题作为重复问题关闭，因为另一个问题没有选择正确答案。
