numba.cuda is dead, long live numba-cuda!

(this is required if you update your nvidia drivers to much, the "builtin" cuda backend will just segfault)

cuda/bindings/_internal/utils.pyx:136: NotSupportedError
What a nightmare...

CUDA-Python 12.9.1 god rid of this error message. CUDA-Python 12.9.0 still has it. 12.9.1 added cuda-pathfinder, which is used instead of the old approach IIUC.

Micket · 2025-11-25T14:08:53Z

side note "12.9.1 added cuda-pathfinder": Should i not have included in this bundle then (i intepret this as cuda-pathfinder not being used here).

So, the problem code is

cdef tuple get_nvjitlink_dso_version_suffix(int driver_ver):
    if 12000 <= driver_ver < 13000:
        return ('12', '')
    else:
        raise NotSupportedError('only CUDA 12 driver is supported')

and
NVIDIA/cuda-python@dd138dc
which removed it with pathfinder, which evidently isn't as strict anymore.

Looking at cuda/core/experimental/_linker.py i see

_nvjitlink = None  # populated if nvJitLink can be used
_nvjitlink_input_types = None  # populated if nvJitLink cannot be used

so, clearly, this code is meant ti work if nvJitLink can't be used, which, seems to be a strict requirement here not to tie the older version up to this. I'm thinking I would just shortcut

def _decide_nvjitlink_or_driver() -> bool:

to never consider nvjitlink.

Micket · 2025-11-25T15:45:47Z

I added a patch to disable nvjitlink as it's to picky about os drivers (for this version of CUDA-Python at least)
