Introduction
Today I used PyInstaller to package my Python program to execute file on Windows, I got an error message:
AttributeError: module 'win32ctypes.pywin32.win32api' has no attribute 'error'After I searching some information on Internet, I found it is a common problem about icon picture of our GUI program. The icon need to use the .ico file, but I use a .png file.
This icon is on the computer desktop dock, not the icon on the program window.
Solution
The easiest way is to find a website on the Internet that can convert images to .ico, for example: https://image.online-convert.com/convert-to-ico
Or maybe you can use the pillow module in Python to convert the image format.
# -*- coding: utf-8 -*-
from PIL import Image
image = Image.open('pic/NightyTimer_Icon.png')
print(image.size)
Output:
(32, 32)
We can save it to .ico extension.
image.save('test.ico', sizes=[(32, 32)])
Dont’ forget to input the sizes argument, otherwise it may be inaccurate.
