Icons missing from PyQt5 app after compiling to .exe using pyinstaller

Question

SOLVED - Solution posted as answer, thanks all for the help.

After compiling my python application using PyQt5 to an executable file, the icons contained in my GUI are removed / not displayed. Specifically QIcon instances added to my Window(QMainWindow) class using self.setWindowIcon(QtGui.QIcon(fpath)) and a QPixmap(f2path) embedded in a QLabel via label.setPixmap(myPixmap).

I have tried to search on this forum for possible solutions but couldn't find a problem solving thread. I've tried to set the absolute filepath as recommended here Bundling data files with PyInstaller (--onefile) and here Missing button icons in pyinstaller

No idea where to start examining problems, there are no errors when compiling with pyinstaller and it runs fine as a python script.

pyinstaller -w -F MY_GUI.py

Thanks in advance!

Example:

import sys
import os

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    base_path = getattr(sys, '_MEIPASS', os.path.dirname(os.path.abspath(__file__)))
    return os.path.join(base_path, relative_path)

import sys
import resource_path # code taken from links above
from PyQt5 import QtGui
from PyQt5.QtWidgets import QApplication, QMainWindow

class Window(QMainWindow):
    def __init__(self):
        super().__init__()

        self.title = "MyProg"
        self.top = 400
        self.left = 400
        self.width = 680
        self.height = 540
        icon_path = resource_path("icon.png")
        self.setWindowIcon(QtGui.QIcon(icon_path))

        self.InitUI()

    def InitUI(self):
        self.setWindowTitle(self.title) 
        self.setGeometry(self.top, self.left, self.width, self.height) 
        self.show()

App = QApplication(sys.argv)
window = Window()
sys.exit(App.exec())

I've tried 3 times to add a friendly 'Hi there' to the top, wouldn't work.. — MalteHerrmann, Oct 04 '18 at 20:40
provide a [mcve]. How do you add the icons? Do you use a relative or absolute path or do you use qresource? — eyllanesc, Oct 04 '18 at 20:44
@MalteHerrmann Please see https://meta.stackoverflow.com/q/251077/1288408 — Modus Tollens, Oct 04 '18 at 20:46
@MalteHerrmann No problem, glad to help! Welcome to Stack Overflow! — Modus Tollens, Oct 04 '18 at 20:54
@MalteHerrmann Are the images on the side of your executable? — eyllanesc, Oct 04 '18 at 21:19
What do you mean? The icon files (png) are in the same folder where the .py file is and the .exe is generated into. — MalteHerrmann, Oct 04 '18 at 21:24
@MalteHerrmann It seems that `pyinstaller` can't infer that you need this png file (not sure what this `resource_path` does behind the scenes). However there are options to [explicitly include data files](https://pyinstaller.readthedocs.io/en/stable/spec-files.html#adding-data-files) in the resulting bundle. Maybe listing your icons there helps. — a_guest, Oct 04 '18 at 21:29
@MalteHerrmann okay, I mean the executable, after you generate the .exe the .py is irrelevant. please use `@username` to notify messages — eyllanesc, Oct 04 '18 at 21:33
@eyllanes the images are all in the same folder as the .exe file is generated, still does not work :( — MalteHerrmann, Oct 05 '18 at 09:11
@a_guest I'll look into your post when I get back to my laptop, thanks for the link! — MalteHerrmann, Oct 05 '18 at 09:11
have you tried to compile with `--icon=path_to_icon` option? — ingvar, Oct 05 '18 at 17:37

@a_guest THANK YOU! Specifying the images as additional data in the `.spec`-file solved my problem! — MalteHerrmann, Oct 05 '18 at 22:13

The solution was to specifically add the image files to the .spec file then generate the .exe file using

$> pyinstaller myGUI.spec

Here is the relevant part of the .spec file:

a = Analysis(['myGUI.py'],
     ...,
     datas = [('myIcon.png', '.')],
     ...)
