CUDA SETUP: Problem: The main issue seems to be that the main CUDA library was not detected.
CUDA SETUP: Solution 1): Your paths are probably not up-to-date. You can update them via: sudo ldconfig.
CUDA SETUP: Solution 2): If you do not have sudo rights, you can do the following:
CUDA SETUP: Solution 2a): Find the cuda library via: find / -name libcuda.so 2>/dev/null
CUDA SETUP: Solution 2b): Once the library is found add it to the LD_LIBRARY_PATH: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:FOUND_PATH_FROM_2a
CUDA SETUP: Solution 2c): For a permanent solution add the export from 2b into your .bashrc file, located at ~/.bashrc

How can I solve this problem, thank you very much

[jb-01]

This worked for me: pip install --upgrade bitsandbytes

[TimDettmers]

Please execute python -m bitsandbytes and paste the output here.

FWIW according to the README it looks like Windows isn't supported, also see #30

[jiluojiluo]

我TM在win 11下跑通了，--quantization_bit 4 这个改成 --quantization_bit 8 ，然后把bitsandbytes-windows-main\bitsandbytes 全量拷贝到C:\Users\用户\AppData\Roaming\Python\Python310\site-packages\bitsandbytes
报错原因是bitsandbytes不支持window，bitsandbytes-windows目前仅支持8bit量化。

[TimDettmers]

As @causztic rightly says, windows is not supported. You can find more information here: #30

Hi @jiluojiluo 可以提供bitsandbytes-windows、bitsandbytes，Python及CUDA的版本号吗？谢谢

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

Replace your SD venv directory file（python.exe Folder） here（J:\StableDiffusion\sdwebui\py310）
