8-bit precision not working on Windows
Closed this issue · 26 comments
It seems like it doesn't like to work on Windows and is unable to detect my cuda installation.

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

bitsandbytes currently does not support windows, but there are some workarounds.
This is one of them: bitsandbytes-foundation/bitsandbytes#30
Thanks, I managed to somehow make it work.
Thanks, I managed to somehow make it work.
How did you manage to make it work? can you share the method?
Basically you have to download these 2 dll files from here. then you move those files into anaconda3\env\textgen\Lib\site-packages\bitsandbytes (assuming you're using conda) after that you have to edit one file in anaconda3\env\textgen\Lib\site-packages\bitsandbytes\cuda_setup edit the main.py with these:
Change ct.cdll.LoadLibrary(binary_path) to ct.cdll.LoadLibrary(str(binary_path)) two times in the file.
Then replace
if not torch.cuda.is_available(): return 'libsbitsandbytes_cpu.so', None, None, None, None
with
if torch.cuda.is_available(): return 'libbitsandbytes_cuda116.dll', None, None, None, None
After that it should let you load the models using 8 bit precision.
EDIT: I celebrated too early, it gives me a cublast error on trying to generate lol
@minipasila THANKYOU SO MUCH! Your instructions + prebuilt bitandbytes for older GPUs https://github.com/james-things/bitsandbytes-prebuilt-all_arch is helping me run Pygmalion 2.7B on my GTX 1060 6GB and it's taking only 3.8 GB VRAM ( out of which prolly 0.4 is being used by the system as I don't have inbuilt graphics )
@minipasila Thank you for sharing, your instructions worked perfectly for GPT-J-6B on 3070ti
For future reference, the 8 bit windows fix required me to navigate to my Python310 install folder instead of the env, as bitsandbytes was not installed in the conda env.
For anybody having troubles still, you can try using newer library - https://github.com/james-things/bitsandbytes-prebuilt-all_arch
Using v37 did it for me finally :)

I still have the same issue I tried everything linked except the v37 fix, I downloaded the dll and put it in the bitsandbytes folder, what next?

Just change libbitsandbytes_cuda116.dll to libbitsandbytes_cudaall.dll in anaconda3\env\textgen\Lib\site-packages\bitsandbytes\cuda_setup\main.py
I followed the suggestions above but when i try to run it with 8-bit precision i get an error window pop up "Bad Image
python.exe libbitsandbytes_cuda116.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f."
EDIT:
Okay, this is weird. I copied the dll from my stable diffusion bitsandbytes folder and it seems to work now.
I got the same error before.
Now I copied the cudaall.dll from stable diffusion bitsandbytes folder instead of cuda116.dll.
It started, even when nothing else has worked!
When attempting to generate with 8-bit using the new libraries suggested by VertexMachine, I get this error.

How do you find the stable diffusion bitsandbytes folder?

It's in this folder: stable-diffusion-webui\venv\Lib\site-packages\bitsandbytes
8-bit should work out of the box with the new one-click installer

Please review response post by @PhyX-Meow re: yuk7/ArchWSL#248. As he points out, it really has nothing to do with your Linux install. It's a simple fix in Windows. The solution he posts is for Arch, but the fix is exactly same for Ubuntu, etc. in a WSL2 install. The issue is that Windows delivers libcuda.so, libcuda.so.1, and libcuda.so.1.1 as fully separate copies of the same file. The fix is just to remove libcuda.so and libcuda.so.1, and just make sym links for each of them to libcuda.so.1.1
Run a command line shell as Administrator, type "cmd" to get a non-powershell command line.
Then type the following commands to create the problematic symbolic links:
C: cd \Windows\System32\lxss\lib del libcuda.so del libcuda.so.1 mklink libcuda.so libcuda.so.1.1 mklink libcuda.so.1 libcuda.so.1.1
when you're done, it will look like this:
**C:\Windows\System32\lxss\lib> DIR ... ... Directory of C:\Windows\System32\lxss\lib 03/15/2022 04:00 PM **
** . 03/15/2022 03:59 PM libcuda.so [libcuda.so.1.1] 03/15/2022 04:00 PM libcuda.so.1 [libcuda.so.1.1]**
Then, just finish your command you were running, in my case, the solution was just run "apt reinstall libc-bin". This is because libc-bin was getting the errors when I had run "apt upgrade -y" command. (see below)The error I received in my "apt upgrade -y" command was two lines: #> apt upgrade -y .... < stuff deleted > ... Processing triggers for libc-bin (2.31-0ubuntu9.7) ... /sbin/ldconfig.real: /usr/lib/wsl/lib/libcuda.so.1 is not a symbolic link ... < stuff deleted > ...
As per @PhyX-Meow
"Actually this is not relate to Arch, nor ArchWSL. It's caused by libcuda.so in your C:\Windows\System32\lxss\lib\ folder not a symbolic link, which is installed by nvidia driver. One solution to [remove] the warning is delete libcuda.so and libcuda.so.1 and use make symbolic link to libcuda.so.1.1. Command line: mklink . Note the command not work in powershell, you shall use cmd.exe."
:)
This seems to be solving the issue for me, still working on it.
torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 160.00 MiB. GPU 0 has a total capacity of 16.00 GiB of which 0 bytes is free. Of the allocated memory 15.06 GiB is allocated by PyTorch, and 54.28 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation.

It means you ran out of memory (try 4bit precision or another quant method like GPTQ/EXL2/GGUF or smaller model) but this error is unrelated to this issue. (sorry for another notification)
Is it not compatible? Even slower is faster than llama...

Ok this is a different error.. so uhh you probably should give a bit more information about your issue like how you installed textgen and what your setup is etc.. potentially just make a new issue because this is probably a different issue than what I made this for originally.
