Research direction

Start by reproducing the pycuda.driver import failure with Python 3.11, CUDA 11.6.2, and Boost.Python on Windows 11. Trace the Boost.Python enum handling implicated by the reported Py_TPFLAGS_HAVE_GC error; done means the import succeeds without that SystemError.

Description

Hello,

in order to test Python 3.11 with pycuda, i have just installed latest pycuda version : 2022.1

I use CUDA 11.6.2 with a windows 11 laptop.

When i try my program (using pycuda), i get this error message :

Traceback (most recent call last):
File "D:\Alain\Astro\Soft\PC\PC_Traitement_Video_V7_51g.py", line 19, in
import pycuda.driver as drv
File "C:\Users\apail\AppData\Local\Programs\Python\Python311\Lib\site-packages\pycuda\driver.py", line 65, in
from pycuda._driver import * # noqa
SystemError: type Boost.Python.enum has the Py_TPFLAGS_HAVE_GC flag but has no traverse function

I also tried with boost.python 1.78 but i get the same issue.

Any help will be appreciate.
