How to change the tkinter icon when using tqdm.tk for a GUI progress bar?

Question

I have this python function that downloads a file and shows the progress bar using tqdm.tk. Now I'm getting the default tkinter icon and I want to change it. How would I do it?

import requests
import os
from tqdm.tk import tqdm

def download_update(url, destination):
   response = requests.get(url, stream=True)
   total_size = int(response.headers.get('content-length', 0))

   print('Update in Progress (Make sure the connection is stable)\n')

   with open(destination, 'wb') as file, tqdm(
       desc='Update in Progress',
       total=total_size,
       unit='B',
       unit_scale=True,
       unit_divisor=1024,  #1024
       colour= '#f8b4aa',
   ) as bar:
       for data in response.iter_content(chunk_size=1024): #1024
           size = file.write(data)
           bar.update(size)

And I get a default warning message in the console which says TqdmExperimentalWarning: GUI is experimental/alpha when I use tqdm.tk. How can I disable it?

Source code for tqdm.tk shows that it keeps main window tkinter.Tk() as self._tk_window so you can try to use

bar._tk_window.iconbitmap("myIcon.ico")

or

from PIL import Image, ImageTk

image = Image.open('image.jpg')    # or `.png`
photo = ImageTk.PhotoImage(image)

bar._tk_window.wm_iconphoto(False, photo)

EDIT:

It seems you may also first create own window, next set icon, and next send this window to tqdm.tk but it creates tqdm as second window (tk.Toplevel()) and icon will be assigned to main window. So it still needs to use bar._tk_window

import tkinter as tk

window = tk.Tk()
window.iconbitmap("main_windown.ico")  # or `window.wm_iconphoto(...)

with ...., tqdm.tk(..., tk_parent=window) as bar:
    bar._tk_window.iconbitmap("progressbar.ico")  # or `window.wm_iconphoto(...)

    # .... rest ...
    bar.update(...)

Full working example. It needs only some image.png.

import time 
from tqdm.tk import tqdm
from PIL import Image, ImageTk

size = 10

with tqdm(total=size) as bar:
    #bar._tk_window.iconbitmap('icon.ico')
    image = Image.open('image.png')    # or `.jpg`
    photo = ImageTk.PhotoImage(image)
    bar._tk_window.wm_iconphoto(False, photo)

    for _ in range(size):
        time.sleep(0.3)
        bar.update(1)
