Hello!
Please tell me how you can save a dictionary with a picture of pil with pickle.
Without pickle, everything works well, and when I connect pickle it does not work, it gives an error:
TypeError: cannot pickle '_tkinter.tkapp' object

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

root = tk.Tk()
root.title('WS_2736_01')
root.geometry('500x500+2+10')


def create_gamer():
    
    id_gamer = '001'
    name     = 'name'
    
    gamer = {'id': id_gamer, 'name': name}
    
    planet_num   = 1
    planet_coord = (100, 100)
    planet_image = fon01_im
    
    planet = {'num':   planet_num, 'coord': planet_coord, 'image': planet_image}
    gamers = {'gamer': gamer, 'planet' : planet}
    
    with open('C:\\ws4\\general\\gamers_prim.pickle', 'wb') as f:
        pickle.dump(gamers, f)
    
    create_map(gamers)



def create_map(gamers):
    im_001 = canvas1.create_image(gamers['planet']['coord'], image = gamers['planet']['image'])


canvas1 = Canvas(root, width = 500, height = 500, bg = "#00EFDD", highlightthickness = 0)    
canvas1.place(x = 0, y = 0)


fon01    = Image.open('C:\\ws4\\general\\gamer_image.PNG').convert('RGBA')
fon01.putalpha(100)
fon01_im = ImageTk.PhotoImage(fon01)

create_gamer()

root.mainloop()

can I somehow save the dictionary with pictures in any way, not necessarily pickle?

I solved the problem with saving the image in the dictionary, but another appeared - the image does not appear in canvas. I know that it’s kind of because of garbage collection, but I don’t remember how to solve it. Tell me please.

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


root = tk.Tk()
root.title('WS_2736_01')
root.geometry('500x500+2+10')


def create_gamer():
    
    id_gamer = '001'
    name     = 'name'
    
    gamer = {'id': id_gamer, 'name': name}
    
    planet_num   = 1
    planet_coord = (100, 100)
    planet_image = Image.open('C:\\ws4\\general\\gamer_image.PNG').convert('RGBA')
    
    planet = {'num':   planet_num, 'coord': planet_coord, 'image': planet_image}
    
    gamers  = {'gamer': gamer, 'planet' : planet}
    
    
    with open('C:\\ws4\\general\\gamers_prim.pickle', 'wb') as f:
        pickle.dump(gamers, f)
    
    with open('C:\\ws4\\general\\gamers_prim.pickle', 'rb') as f:
        uni = pickle.load(f)
    
    if gamers == uni:
        print('OK')
        print(gamers['planet']['image']) #<PIL.Image.Image image mode=RGBA size=60x60 at 0x201220BC730>
        print(uni['planet']['image'])    #<PIL.Image.Image image mode=RGBA size=60x60 at 0x20121CFF6D0>
    
    create_map(gamers)



def create_map(gamers):
    
    fon_003 = gamers['planet']['image']
    fon_003.putalpha(100)
    fon003_im = ImageTk.PhotoImage(fon_003)
    im_001 = canvas1.create_image(gamers['planet']['coord'], image = fon003_im)


canvas1 = Canvas(root, width = 500, height = 500, bg = "#00EFDD", highlightthickness = 0)
canvas1.place(x = 0, y = 0)


create_gamer()

root.mainloop()

def create_map(gamers):
    
    fon_003 = gamers['planet']['image']
    fon_003.putalpha(100)
    fon003_im = ImageTk.PhotoImage(fon_003)
    im_001 = canvas1.create_image(gamers['planet']['coord'], image = fon003_im)
    canvas1.image = fon003_im

solved the problem! if anyone is interested - added a link to the image and it appeared:
canvas1.image = fon003_im
