Bundling data files with PyInstaller (--onefile)

Question

I\'m trying to build a one-file EXE with PyInstaller which is to include an image and an icon. I cannot for the life of me get it to work with --onefile.

All of the other answers use the current working directory in the case where the application is not PyInstalled (i.e. sys._MEIPASS is not set). That is wrong, as it prevents you from running your application from a directory other than the one where your script is.

A better solution:

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)
