i installed the cuda drivers

Feb 12 '23 00:02 mrcjh079

Do you have CUDA Toolkit installed? I had a similar problem and was able to fix it by installing it from the official NVIDIA page.

Feb 12 '23 13:02 Thund3rPat

it is installed idk whats wrong

Feb 12 '23 14:02 mrcjh079

the same error before and after installing it

Feb 12 '23 14:02 mrcjh079

Same here, even after installing the newest CUDA drivers

Feb 12 '23 20:02 ftenrique

I have tried installing CUDA 11.0, 11.6, 11.7, 12.0, all still showing the same error

What else would come to my mind would be to disable 8bit adam. However, this would lead to a very high memory consumption...

Feb 13 '23 22:02 Thund3rPat

I am having this exact same issue.

This worked for me!

Finally, I found the cause of this problem. It is caused by the bitsandbytes library not supporting Windows. kohya_ss use this library to support 8bit adam to reduce video mem usage. There is a windows compatible version in the bitsandbytes_windows folder. Execute below script in Readme Installation maybe fix this problem.

cp .\bitsandbytes_windows\*.dll .\venv\Lib\site-packages\bitsandbytes\
cp .\bitsandbytes_windows\cextension.py .\venv\Lib\site-packages\bitsandbytes\cextension.py
cp .\bitsandbytes_windows\main.py .\venv\Lib\site-packages\bitsandbytes\cuda_setup\main.py

I got this error because I forgot to first activate the virtual environment.

.\venv\Scripts\activate
python .\lora_gui.py

All the solutions above don't work. Solutions from other opened threads don't work either.

Why even make the main instruction for linux when 90% of sd users run windows?

When I run this code, it gives numerous errors and when one error is solved, another pops out. It is a nightmarish experience. Esp having a nice gpu, Jesus.

Also, why even redirect us to bitsandbytes when all the recent opened issues are silently ignored?

Having the same problem

Mar 03 '23 21:03 filliptm

found my problem. If you installed the repo with CMD it didn't copy those bitsandbytes files into the directories. Powershell as admin will do the thing. or you can copy them in manually as I did and it fixed the problem

cp .\bitsandbytes_windows*.dll .\venv\Lib\site-packages\bitsandbytes
cp .\bitsandbytes_windows\cextension.py .\venv\Lib\site-packages\bitsandbytes\cextension.py cp .\bitsandbytes_windows\main.py .\venv\Lib\site-packages\bitsandbytes\cuda_setup\main.py

Mar 03 '23 22:03 filliptm

发现我的问题。如果您使用 CMD 安装了 repo，它不会将那些 bitsandbytes 文件复制到目录中。作为管理员的 Powershell 会做这件事。或者你可以像我一样手动复制它们并解决问题

cp .\bitsandbytes_windows*.dll .\venv\Lib\site-packages\bitsandbytes cp .\bitsandbytes_windows\cextension.py .\venv\Lib\site-packages\bitsandbytes\cextension.py cp .\bitsandbytes_windows\main.py 。 \venv\Lib\site-packages\bitsandbytes\cuda_setup\main.py

I have tried manually copying all the files in the .\kohya_ss\bitsandbytes_windows folder to the ".\kohya_ss\venv\Lib\site-packages\bitsandbytes" folder, but it still doesn’t solve the problem. What should I do for Windows users?

My problem is solved, must use Powershell to execute these commands, manual can not fix this problem

Still get the same error

You can indeed use explorer to copy them manually. Here are the files you need to copy:

Copy to: venv\Lib\site-packages\bitsandbytes\

    bitsandbytes_windows\cextension.py
    bitsandbytes_windows\libbitsandbytes_cpu.dll
    bitsandbytes_windows\libbitsandbytes_cuda116.dll

Copy to: venv\Lib\site-packages\bitsandbytes\cuda_setup\

    bitsandbytes_windows\main.py
