• If possible, make a PR with a failing test to give us a starting point to work on!

Describe the bug

Traceback (most recent call last):
File "/test_cudaq.py", line 2, in
import cudaq
File "lib/python3.11/site-packages/cudaq/init.py", line 53, in
from .kernel.kernel_decorator import kernel, PyKernelDecorator

ImportError: [custatevec] %unknown error in check_gpu_compatibility (line 36)

Steps to reproduce the bug

create file test_cudaq.py
import cudaq

run it

Expected behavior

should not raise an error as code comes from cudaq docs itself

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression

Environment

• CUDA-Q version: 0.9.0
• Python version: 3.11.9
• C++ compiler: g++ 13.3.0
• Operating system: Ubuntu 24.04.1 LTS

Suggestions

using Quadro T1000 with Max-Q GPU.

Hi @petacube - thank you for reporting this issue. Do you know what version of CUDA you have installed? It would be helpful if you could run the nvidia-smi command and paste the output back into this thread.

I believe your GPU is Compute Capability 7.5 (according to https://developer.nvidia.com/cuda-gpus), but it good to double check that with this command: nvidia-smi --query-gpu=compute_cap --format=csv.

[petacube]

yes its 7.5 what is the minimum?
