Why does an error occur when loading an image in PIL PhotoImage?

Question

Python

Foreword:
Perhaps I do everything through one place? And is there another option to constantly capture the image of the game with further processing and display the processed image in the window? It seems that there is still PyQT - will it be easier to do? I am not familiar with python, I write code according to the documentation of libraries on the Internet.
******
The task is to take a screenshot of the screen area with the game, put it in a variable for further actions in OpenCV and display this image in the TkInter window.
Includes:

from Tkinter import *
import cv2 as cv
import win32gui
from PIL import ImageOps, Image, ImageGrab, ImageTk
from numpy import *

We get the image (the main function is get_screen, the result of the function is perfectly processed by the OpenCV library without errors:

WINDOW_SUBSTRING="Game Window Name"

def set_window_coordinates(hwnd, window_info):
    if win32gui.IsWindowVisible(hwnd):
        if WINDOW_SUBSTRING in win32gui.GetWindowText(hwnd):
            rect = win32gui.GetWindowRect(hwnd)
            x = rect[0]
            y = rect[1]
            w = rect[2] - x
            h = rect[3] - y
            window_info['x'] = x
            window_info['y'] = y
            window_info['width'] = w
            window_info['height'] = h
            window_info['name'] = win32gui.GetWindowText(hwnd)
            win32gui.SetForegroundWindow(hwnd)


def get_screen(x1, y1, x2, y2):
    box = (x1 + 8, y1 + 30, x2 - 8, y2)
    screen = ImageGrab.grab(box)
    img = array(screen.getdata(), dtype=uint8).reshape((screen.size[1], screen.size[0], 3))
    return img


def get_window_info():
    # set window info
    window_info = {}
    win32gui.EnumWindows(set_window_coordinates, window_info)
    return window_info

We create an interface and load an image into it:

def loop():
    window_info = get_window_info()
    root = Tk()
    root.title("GUI on Python")

    img = get_screen(
        window_info["x"],
        window_info["y"],
        window_info["x"] + window_info["width"],
        window_info["y"] + window_info["height"]
    )
    root.geometry(str(window_info["width"]) + "x" + str(window_info["height"]))

    #print img
    photo = PhotoImage(image=img) # - тут выдается ошибка
    #btn = Button(text="Click Me", background="#555", foreground="#ccc",
    #             padx="20", pady="8", font="16", command=click_button)
    photo.pack()
    #btn.pack()

    root.mainloop()


loop()

An error:

self.tk. call(('image', 'create', imgtype, name,) + options)

Process finished with exit code 1

I don’t understand why the Unknown option, because even in the library file itself this moment is processed - opened, looked.

This is not a named parameter. Just
photo = PhotoImage(img)
