   Hi @leviome, I'm assuming that the code shared is just a snippet of the API call after you've already created a GL context. When I run the snippet as is, I get cudaError_t.cudaErrorInvalidGraphicsContext which seems expected since a GL context needs to be created before this call IIUC.

   However, here's what I ran to attempt a repro:

   # need to install pygame, pyopengl, cuda-python (best through conda-forge)
   import pygame as pg
   from OpenGL import EGL
   from cuda import cudart
   
   if __name__ == "__main__":
       pg.init()
       display_size = (640, 480)
       pg.display.set_mode(display_size, pg.OPENGL | pg.DOUBLEBUF | pg.RESIZABLE)
       # check opengl context is created
       assert EGL.eglGetCurrentContext() is not None
       print(cudart.cudaGLGetDevices(1, cudart.cudaGLDeviceList.cudaGLDeviceListAll))
   

   but this returns cudaError_t.cudaSuccess, implying that the bindings are working as expected. Therefore it's likely there's something happening in one of your prior calls or how your system is configured.

   If you think there're prior calls that complicate the binding of cudaGLGetDevices API, a full snippet would be helpful. Otherwise the bindings look ok, so this issue can be closed.
