Pyinstaller and --onefile: How to include an image in the exe file

This is a variation of the following: Bundling data files with PyInstaller (--onefile), and the given answer is clearer.

In 2 lines:

1. You have to add your image files in "datas" (either in your spec files or with a PyInstaller hook script)
2. Use the sys._MEIPASS if it exists,
   using the single line base_path = getattr(sys, '_MEIPASS', '.')+'/' to get a "root_path" variable to concatenation to all your files' paths.
   Then, filepath = base_path + filepath

Edit:

I belive I found the solution to my problem.

# -*- mode: python -*-
a = Analysis(['AMOS_Visualizer.py'],
         pathex=['C:\\Users\\elu\\PycharmProjects\\Prosjektet\\Forsok splitting'],
         hiddenimports=[],
         hookspath=None,
         runtime_hooks=None)

for d in a.datas:
    if 'pyconfig' in d[0]:
        a.datas.remove(d)
        break

a.datas += [('Logo.png','C:\\Users\\elu\\PycharmProjects\\Prosjektet\\Forsok splitting\\Logo.png', 'Data')]
pyz = PYZ(a.pure)
exe = EXE(pyz,
      a.scripts,
      a.binaries,
      a.zipfiles,
      a.datas,
      name='AMOS_Visualizer.exe',
      debug=False,
      strip=None,
      upx=True,
      console=True, icon='C:\\Users\\elu\\PycharmProjects\\Prosjektet\\Forsok splitting\\AMOS.ico')

And adding the following to my main.py script

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    try:
        # PyInstaller creates a temp folder and stores path in _MEIPASS
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    return os.path.join(base_path, relative_path)

Logo = resource_path("Logo.png")

If you are using Qt Designer you can do it by creating an resource file and adding all images you want, including the Logo.png, to this resource.

To create a resource file you can follow the steps in Inserting an image in GUI using QT Designer .

After you have inserted the images in the resource file, assign the Logo.png to the Window icon, save the QtDesigner interface and convert the resource file using the command: pyrcc4 -py3 resourcetest.qrc -o resourcetest_rc.py

Finally, use --onefile option to create the exe file. No need to edit the spec file.
