windows10 anaconda error

[Fuger2021]

i run the command in my conda env:

conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 -c pytorch -c nvidia

and it automatically installed pytorch-cuda 11.3 for me. then i upgraded pytorch-cuda manually:

conda install pytorch-cuda=11.6 -c pytorch -c nvidia

and then

pip install git+https://github.com/Keith-Hon/bitsandbytes-windows.git

but when i run python -m bitsandbytes, i got the following error messages:

> python -m bitsandbytes

    check_cuda_result(cuda, cuda.cuDeviceGetCount(ct.byref(nGpus)))
AttributeError: 'NoneType' object has no attribute 'cuDeviceGetCount'

and the code causing error is:

def get_cuda_lib_handle():
    # 1. find libcuda.so library (GPU driver) (/usr/lib)
    try:
        cuda = ct.CDLL("libcuda.so")
    except OSError:
        CUDASetup.get_instance().add_log_entry('CUDA SETUP: WARNING! libcuda.so not found! Do you have a CUDA driver installed? If you are on a cluster, make sure you are on a CUDA machine!')
        return None
    check_cuda_result(cuda, cuda.cuInit(0))

    return cuda

that means i got an OSError and return None.

what should i do?
