Problem loading important libraries when using py2exe

Question

I am trying to make a small weather app. Everything going perfect with my codes, except when i used this code to have a systray icon:

from pystray import MenuItem as item
import pystray

def quit_window(icon, item):
    icon.stop()
    main.destroy()

def show_window(icon, item):
    icon.stop()
    main.after(0,main.deiconify)

def withdraw_window():  
    main.withdraw()
    image = Image.open("logo2.ico")
    menu = (item('Show', show_window), item('Quit', quit_window))
    icon = pystray.Icon("weather app", image, "weather app", menu)
    icon.run()

main.protocol('WM_DELETE_WINDOW', withdraw_window)

And i tried to make my app as a stand alone application by using py2exe. When i finished exporting my app to exe and tried to start it i got this error:

Traceback (most recent call last):
File "Weather-V102.pyw", line 9, in <module>
