Have you installed all the missing dependencies? Canvas is part of Tkinter. I know I missed adding the requirements.txt file and will do that as soon as possible.

I think Tkinter is not available anymore so used this-

import tkinter as tk
master = tk.Tk()

[saurabhbidwai]

this is working
w = tk.Canvas(master, width=canvas_width, height=canvas_height + 20)
b = tk.Button(master, text="Predict", command=call_predict)
