bitsandbytes was compiled without GPU support. 8-bit optimizers and GPU quantization are unavailable. about bitsandbytes

[TimDettmers]

The binary that is used is determined at runtime. This means in your case there are two modes of failures:

• the CUDA driver is not detected (libcuda.so)
• the runtime library is not detected (libcudart.so)

Both libraries need to be detected in order to find the right library for the GPU/CUDA version that you are trying to execute against.

Could you please provide use with the output of python -m bitsandbytes for the GPU job that you are trying to run?

I think I'm in a similiar boat trying to get this to engage with the python version of dreambooth-sd

hi, same issue, exact same use-case too haha

I know Im using a cuda-enabled machine

I believe this is fixed in the latest version. It prints instructions on how to debug the situation and alternatively prints out compilation instructions which should fix the issue.

I had the same issue, (nvidia-smi had proper output, but was still getting this error)

1. I've downloaded cuda drivers from nvidia's website, and followed their instructions:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-12-0_12.0.1-1_amd64.deb
sudo dpkg -i cuda-12-0_12.0.1-1_amd64.deb

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin
sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-drivers_525.85.12-1_amd64.deb
wget https://developer.download.nvidia.com/compute/cuda/repos/$distro/$arch/cuda-keyring_1.0-1_all.deb
sudo dpkg -i cuda-keyring_1.0-1_all.deb
sudo apt-key del 7fa2af80

sudo apt-get install cuda

2. it failed and messed up my debian package graph, (I've done a bunch of below, it will be different on other systems but just to document)

sudo apt --fix-broken install
sudo systemctl stop nvidia-powerd
sudo apt-get remove nvidia-kernel-common-515
sudo dpkg -r nvidia-compute-utils-525
sudo dpkg -i --force-overwrite /var/cache/apt/archives/nvidia-compute-utils-525_525.85.12-0ubuntu1_amd64.deb
sudo dpkg --configure -a
sudo apt-get install -f

3. Once everything is sorted out, rebooted the system:

sudo reboot

Now it works.

Bitsandbytes was not supported windows before, but my method can support windows.（yuhuang）
1 open folder J:\StableDiffusion\sdwebui，Click the address bar of the folder and enter CMD
or WIN+R, CMD 。enter，cd /d J:\StableDiffusion\sdwebui
2 J:\StableDiffusion\sdwebui\py310\python.exe -m pip uninstall bitsandbytes

3 J:\StableDiffusion\sdwebui\py310\python.exe -m pip uninstall bitsandbytes-windows

4 J:\StableDiffusion\sdwebui\py310\python.exe -m pip install https://github.com/jllllll/bitsandbytes-windows-webui/releases/download/wheels/bitsandbytes-0.41.1-py3-none-win_amd64.whl
