Feature Request: ROCm support (AMD GPU)

[gururise]

Could you please add official AMD ROCm support to this library? An unofficial working port already exists:

https://github.com/broncotc/bitsandbytes-rocm

Thank You

[TimDettmers]

Amazing! Thank you for bringing this to my attention. I will try to get in touch with the author of the ROCm library and support AMD GPUs by default.

that would be AMAZING! especially with you recently adding 8 bit support. I tried to make my own merge of the forks but I don't really know what I'm doing and don't think I did it correctly

[anonymous721]

If the ROCm fork does get merged in, would the Int8 Matmul compatibility improvements also work for AMD GPUs?

[deftdawg]

@TimDettmers, curious if AMD support any nearer to being merged? @agrocylo made a PR (#296) based somewhat on @broncotc's fork...

EDIT: A slightly newer version branched from v0.37 available here:

[elukey]

The Wikimedia foundation is really interested in the ROCm support too, since Nvidia is not viable for us due to open-source constraints. @TimDettmers we offer any help (testing/review/etc..) to help merge this feature, it would be really great for the ML open source ecosystem. Thanks in advance!

Hi,
I'm also seeking an AMD-GPU-compatible version.
I tried your patch-2 version but the code still cannot work.
The error info looks like:

I use AMD MI200 card.
Do you have any idea on this?
Many thanks.

Hello, I was wondering how far-off the ROCm support is. I'm trying to see if my 7900XTX will be useful in a project of mine. The Llama2 quick start guide makes use of bitsandbytes, and as far as I know there isn't any other alternatives.

[jiagaoxiang]

Found this rocm version of bitsandbytes: https://github.com/Lzy17/bitsandbytes-rocm/tree/main

[mauricioscotton]

The only rocm version that worked for me on GFX900 was this one: https://github.com/agrocylo/bitsandbytes-rocm
All the others failed to compile/install
(Rocm 5.2)

[st1vms]

For anyone that needs a patch for RDNA3 cards I created this fork https://github.com/st1vms/bitsandbytes-rocm-gfx1100

This fork patches the Makefile for targeting gfx1100 amdgpu module along latest ROCM and clang17...and fixes some hip include warnings.

Works with a RX7900XT and ROCM5.7 (along with torch-rocm5.7) installed.

Anyway there should be a better way of targeting the correct amdgpu module in the build system...

Edit:

Probably won't work with libraries requiring version > 0.35

[Wintoplay]

@st1vms There is a problem.
The version of BNB is 0.35.4 which is kind of outdated, and the latest version of Peft requires bitsandbytes>=0.37.0

[st1vms]

@st1vms There is a problem.
The version of BNB is 0.35.4 which is kind of outdated, and the latest version of Peft requires bitsandbytes>=0.37.0

If that fork still works for you, maybe it is ok to just change the version number.

You can test if the library works with:

python -m bitsandbytes

If that is the case, try editing the version number in the setup.py of the fork before building and installing it, i.e. change it to 0.37.0 and see if Peft works...

[Wintoplay]

@st1vms I tried BNB 0.39.0
The dependencies seem fine. However, when I tried to lora finetune according to this https://colab.research.google.com/drive/1jCkpikz0J2o20FBQmYmAGdiKmJGOMo-o?usp=sharing

The Jupyter kernel crash, reason: undefined

Well, the fork is probably obsolete already for some libraries, you should look for updated ones.

[Wintoplay]

@st1vms
I retried with a new virtual env and change from .ipynb to .py
This is the result.

Can someone post to this thread any updated forks? The lack of proper BnB support is really holding back the AMD cards.

[gururise]

Looks like things may finally move forward with official support in the not too distant future! Hope with ROCm 6.x we can finally see support merged into this repo.

[TimDettmers]

Sorry for taking so long on this. I am currently onboarding more maintainers and we should see some progress on this very soon. This is one of our high-priority issues.

[SakshamG7]

Would love to see ROCM support, keep doing your good work

[PatchouliPatch]

if I may ask, what's the progress so far?

[Airradda]

if I may ask, what's the progress so far?

If you haven't already seen it, there was a comment made in the discussions with an accompanying tracking issue for general cross-platform support rather than just AMD/ROCM support. To that end it appears it is currently in the planning phase.

[amathews-amd]

@TimDettmers @Titus-von-Koeller , we are at ~95% parity for bnb for https://github.com/ROCm/bitsandbytes/tree/rocm_enabled on Instinct class gpus, and working to close the gaps on Navi. At this point, we should be seriously considering upstreaming. Could you drop me an email at aswin.mathews@amd.com, and we can set up a call to discuss further.

[chauhang]

@amathews-amd I tired compiling ROCm version of BnB from the rocm_enabled branch, but it is failing with errors on AMD MI250x. Do you have any suggestions for how to resolve the issue?

[pnunna93]

@chauhang Could you try with rocm 6.0? You can use this docker - rocm/pytorch:rocm6.0.2_ubuntu22.04_py3.10_pytorch_2.1.2 and install bitsandbytes directly.

[chauhang]

@pnunna93 I am already using ROCm 6.0 -- have added details of the pytorch environment here.

[pnunna93]

@chauhang, you can skip the hipblaslt update and install bitsandbytes directly then. Please let me know if you face any issues.

[ehartford]

I was using arlo-phoenix fork. https://github.com/arlo-phoenix/bitsandbytes-rocm-5.6/tree/rocm

Should I use the ROCm fork instead? https://github.com/ROCm/bitsandbytes/tree/rocm_enabled

[pnunna93]

Yes, its updated for rocm 6

I've often had trouble understanding the state of GPU support in ROCm. So with that said, I have some clarification questions:

• Can we clarify on what we mean by "Instinct-class" GPUs?
  • The ROCm 6.0.2 docs suggest to me this is all CDNA, so MI100 and newer? Or is MI50 expected to work also?
• What is the intention for Navi support?
  • Is this for RDNA2/RDNA3 only?
• Is there intent to support with ROCm < 6?

I'd like to be able to help get this merged, but need to figure out the constraints. The only AMD GPUs that I have on hand (RX 570 and R9 270X) aren't going to cut it.

The other issue is how far behind main this is. Ideally this could be implemented as a separate backend as proposed in #898. We would want to change to use CMake for building. I also think that it'd be better to unify the C++/CUDA code with the hipify code and take care of most of the changes with conditional compilation.

[amathews-amd]

Sure, here is the official list: https://rocm.docs.amd.com/projects/install-on-linux/en/latest/reference/system-requirements.html#supported-gpus. For BnB, since we are at initial enablement, it is dependent on where we are testing it (both hardware and software versions). We are currently focusing on MI250/MI300/gfx1100, and newer ROCm versions for testing.
We are assessing #898 as well, to see how we can adapt the rocm_enabled branch, so it fits in the new design.

@amathews-amd I sent you an invite to our bnb-crossplatform slack, to the email you provided. Of course we should invite your other collaborators as well. Can we talk there and coordinate on scheduling a kickoff call?

[Titus-von-Koeller]

@amathews-amd the changes introduced through #898 are not final and weren't merged onto main but instead multi-backend-refactor in order to keep main releasable and allow us to iteratively arrive at a solution that works for all parties involved.

This means that there's ongoing work where a series of PRs onto multi-backend-refactor will concretize things further in tight collaboration with the community. Feel free to pitch in with opinions and concrete work, in case there's something that catches your eye and fits your expertise.

[PatchouliPatch]

is there a place where we can track the progress on the implementation of this?

by the way, does anyone know where I can submit bug reports for https://github.com/ROCm/bitsandbytes/tree/rocm_enabled? going to the page, there's no Issues tab.

Maybe @pnunna93 or @amathews-amd from AMD can help with that? I'm sure they'd appreciate your report.

Right now the best place is to look at PRs and recently merged PRs to the multi-backend-refactor branch.

We should make significant progress in the next weeks and make a alpha/beta release built off of that branch available as a nightly package release relatively soon.
