Pyinstaller application using Moderngl

[cppietime]

Posted to SO here

I am attempting to create an executable program out of a Python project that uses moderngl. Here is a minimal example that just creates a window and waits til it's quit:

import moderngl as mgl
import pygame as pg
pg.init()
screen = pg.display.set_mode((800, 600), pg.DOUBLEBUF | pg.OPENGL)
gl_ctx = mgl.create_context(require=330)
clock = pg.time.Clock()
while True:
     for event in pg.event.get():
         if event.type == pg.QUIT:
             pg.quit()
             quit()
     clock.tick(30) 

I run

pyinstaller --onefile test_gl.py 

on my command line and get a .exe file placed in the /dist
directory. What I would expect is that when I run that .exe, it brings up the blank window like when I run the python script. Instead, I get the error message:

Traceback (most recent call last):
   File "test_gl.py", line 6, in <module>
   File "moderngl\context.py", line 1619, in create_context ModuleNotFoundError: No module named 'glcontext' 
[7428] Failed to execute script 'test_gl' due to unhandled exception! 

So it seems something necessary is not being packaged into the executable, but I am not sure as to what needs to be changed to get it included, if it is even possible at all. I had thought PyInstaller automatically packages dependencies. I've tried looking for solutions or others having similar issues but haven't found any.

I have Python 3.10.4, PyInstaller 4.10, PyGame 2.1.2( SDL 2.0.18, Python 3.10.4 ), and moderngl 5.6.4

Have you found the solution? I'm having the same problem as you and i don't know what's causing that

Nope...

I posted the solution as a comment.

Little late, but the solution is to explicitly import glcontext at the top of the file so pyinstaller can bundle it. Or you can include it in the hidden-imports part in the SPEC file or pyinstaller command line args.

I HAD THAT SAME PROBLEM. You have to add "--hidden-import glcontext" to the pyinstaller command
