Problem with pycuda and python 3.11

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.

Alain

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.
