Why is this code throwing error after compiling

Question

I made a script and it works perfectly but when I compile it with pyinstaller

pyinstaller --onefile --icon='icon.ico' dmi.py

It throws error, but if I don't compile it works

I know Github module is throwing error. This is the code which throwing error:

import PySimpleGUIQt as Sg
from github import Github
from urllib import parse

g = Github("ghp_**********************************")
img_data = (g.get_user().get_repo('python-files')).get_contents(
    parse.quote('create.ico'), ref="main").content.replace('\n', '').encode()

layout = [
    [Sg.Text('                                                     ')]
]
window = Sg.Window("Add Tags", layout, icon=img_data, resizable=False, finalize=True)
while True:
    event, values = window.read()
    if event == Sg.WINDOW_CLOSED:
        window.close()
        break

The code below works even after compiling:

import base64
import PySimpleGUIQt as Sg
import requests
header = {"Authorization": "token ghp_*******************************",
          "Accept": "application/vnd.github.v4.raw"}
encoded = base64.b64encode((requests.get('https://raw.githubusercontent.com/WoLvES-2x0/python-files/main/create.ico', headers=header)).content)
layout = [
    [Sg.Text('                                                     ')]
]
window = Sg.Window("Add Tags", layout, icon=encoded, resizable=False, finalize=True)
while True:
    event, values = window.read()
    if event == Sg.WINDOW_CLOSED:
        window.close()
        break

although I can do this in other way but main issue I'll face without this is

Get file name of all files in a repo

g_f_name = [str(i).replace('ContentFile(path="', '').replace('")', '') for i in (g.get_user().get_repo('node-files')).get_contents('') if i]

And commit changes to repo

repo.update_file(repo.get_contents('tags.txt').path, "committing files", tags_string, repo.get_contents('tags.txt').sha, branch="main")

error Is

ModuleNotFoundError: No module named '_cffi_backend'
[33116] Failed to execute script 'dmi' due to unhandled exception!

Answer 1

importing

import _cffi_backend

solves the issue, what I think is Pyinstaller somehow misses this module while compiling, and PyGithub need this module, Although in editor this grayed out but it works
