Multi-backend refactor: Alpha release ( AMD ROCm ONLY )

[Titus-von-Koeller]

This space is intended to receive feedback from users that are willing to help us by alpha testing the current implementation of the AMD ROCm backend.

Issues to discuss could be

• bugs
• installation
• needed docs
• performance
• ease of use
• ... you name it ...

Thanks everyone for you kind support and please remember to have a constructive tone 🤗

Trying to install on ubuntu 22.06 rocm 6.1.2 and I can't pass the compilation with the following error:

-- Configuring bitsandbytes (Backend: hip)

CMake Error at /opt/rocm/lib/cmake/hip-lang/hip-lang-config.cmake:126 (message):
hip-lang Error:Permission denied - clangrt builtins lib could not be found.

I have been using InvokeAI (version 5 now 😸). Installing the multi-backend-refactor version of bitsandbytes eliminated an annoying "stutter"/freezing issue that I had at the start of generation making the whole process much more enjoyable.
Installation was straight forward enough. (Except the install instructions seem to have moved from the link provided at the non_cuda_backends docs page -> current install instruction link)

(on archlinux, rocm v6.2.1)

Linux 6.10.10-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 12 Sep 2024 17:21:02 +0000 x86_64 GNU/Linux
I am on archlinux with 7600 XT , everything works except bitsandbytes (torch , onnxruntime, etc ..)

I have tried 5.7 python packages with rocm 6.0.2 official archlinux build - bitsandbytes failed
Then I have tried 6.1 whl packages with 6.2 aur opencl-amd-dev package , then again could not make bitsandbytes work.

followed AMD ROCM site instructions and checked out mutli-backend-refactor

Why does it think rocm version as cuda version and HSA as compute capability isnt it confusing code. I have checked version checking init.py , it struggled finding tag and versioning for a while and then I have checked out latest commit and it somehow managed.

git branch --show-current
rocm_enabled
git rev-parse HEAD
c336a2644c6590e16a1d64cc695a06523bb9824e
git describe --tags --always --dirty --long
0.41.0-355-gc336a26

Could you help me out please ? I want to be able to use 8 Bit and 4 Bit Quantization function.
Thank you

I recently came across this, not sure if it is helpful: https://github.com/ROCm/bitsandbytes

[LeonardoSidney]

the command from the documentation:

git clone --depth 1 -b multi-backend-refactor https://github.com/bitsandbytes-foundation/bitsandbytes.git && cd bitsandbytes/

Generates this problem:

File "<string>", line 58, in <module>
        File "<string>", line 40, in get_version_and_write_to_file
        File "<string>", line 30, in get_latest_semver_tag
      ValueError: No valid semantic version tags found

Using the command:

git clone -b multi-backend-refactor https://github.com/bitsandbytes-foundation/bitsandbytes.git && cd bitsandbytes/

I can run the build.
It's probably a problem with missing tags since we're using a different name than the standard branch tag name.
I don't know much about semver, I just solved this by cloning the entire repo and it (semver) arbitrarily chose a tag to generate the build.

These are the commands I used for compilation:

python3.11 -m venv venv

source venv/bin/activate

# torch 2.4.1
pip3 install torch --index-url https://download.pytorch.org/whl/rocm6.1

pip install -r requirements-dev.txt

cmake -DBNB_ROCM_ARCH="gfx1100" -DCOMPUTE_BACKEND=hip -S .

make -j16

pip install -e .

Ironically, it's Arch Linux that's out of date. It's still using rocm6.0.

python -m bitsandbytes:

ROCm Setup failed despite ROCm being available. Please run the following command to get more information:

python -m bitsandbytes

Inspect the output of the command and see if you can locate ROCm libraries. You might need to add them
to your LD_LIBRARY_PATH. If you suspect a bug, please take the information from python -m bitsandbytes
and open an issue at: https://github.com/TimDettmers/bitsandbytes/issues

Checking that the library is importable and ROCm is callable...
Couldn't load the bitsandbytes library, likely due to missing binaries.
Please ensure bitsandbytes is properly installed.

For source installations, compile the binaries with `cmake -DCOMPUTE_BACKEND=hip -S .`.
See the documentation for more details if needed.

Trying a simple check anyway, but this will likely fail...
