Pyinstaller:unable to create onefile .exe which has .png file

I was creating a tkinter program which I need to make into exe so I can send it to my friends. so for this program, I needed to add a .png and .ico file. Here is the code I typed in pyinstaller to install the exe

pyinstaller .\u.py -F --noconsole --add-data 'C:\Users\Binoy\Desktop\Techwiz\h.png; .' -i ".\h.ico"

This is my .spec file:

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['U.py'],
             pathex=['C:\\Users\\Binoy\\Desktop\\New folder'],
             binaries=[],
             datas=[('C:\\Users\\Binoy\\Desktop\\Techwiz\\h.png', '.')],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='U',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=False , icon='h.ico')

I also got a .txt file regaridng missing modules but in the .txt,they said that these modules won't affect the .exe so I didn't care about it.At first it was running without any problem but then if I delete the .png or if one of my friends download it,it shows the error Failed to execute script U. so I tried the resource_path() function (Pyinstaller and --onefile: How to include an image in the exe file),but didn't work. So I created a .bat file (Keep error message of exe file which is created by Pyinstaller),and got this error:

Traceback (most recent call last):
File "U.py", line 19, in <module>
File "tkinter\__init__.py", line 4062, in __init__
File "tkinter\__init__.py", line 4007, in __init__
_tkinter.TclError: couldn't open "C:/Users/Binoy/Desktop/Techwiz/h.png": no such file or directory
[8736] Failed to execute script U

Is there any way to store images(.png) with the .exe file as a single .exe file?

Solution

Joran Beasley is right with his comment. You may have some issues with your path setup. If I want to want to compile an executable, that has also extern files included, I use the following approach

from PIL import Image
import os
import sys

#check if its a compiled exe
if getattr(sys, 'frozen', False) and hasattr(sys, '_MEIPASS'):
    filePath = os.path.join(sys._MEIPASS, "test_picture.png")
#otherwise it must be a script 
else:
    scriptPath = os.path.realpath(os.path.dirname(sys.argv[0]))
    filePath = os.path.join(scriptPath, "test_picture.png")

f = Image.open(filePath).show()

In this example, the 'test_picture' will be relative to the script, if a run it as a .py file. Otherwise, it will be stored in the temporary _MEI folder. Latter one is defined via

datas = [...]

which you already did in your spec file.

Also, if you run a pyinstaller executable, you may want to check the following path.

C:\Users...\AppData\Local\Temp\

There should be a folder, called _MEI followed by some numbers. This is the folder where your executable will be extracted, as well as all the data you included
