Thank you! We are planning to switch to make, and this is a great PR!

I do not have an overview of how this is different or could benefit from #220 and #229. Could you please have a look and discuss the differences and if we could benefit from some of the old code. Thank you!

I would recommend building only the native library here using a build matrix, then a separate job to build the Python binary wheels.

Is this PR complete? I remember there being some Windows-specific stuff needed, also some things for Linux/Arm64 that required specific handling. Unfortunately the original PRs (#220 etc) cannot be viewed because of force pushes. I'll see if I can dig up a relevant diff

Windows specific stuff extracted on PR #873 and #876
See also https:/wkpark/bitsandbytes/actions (several times compiled, partial squashed rebased blah blah..)

(and pytest stuff is not fixed/tested much since I have no sm_75 capable GPU.)

I don't have a Windows machine at hand right now, but there are also specific compiler flags that MSVC needs. I think this is what PR #220 did.

I spend a few minutes to rebase and create a draft PR in #947 just for reference, which should compile on all platforms. Maybe it's worth just comparing notes on those?

@wkpark @TimDettmers
I extracted the relevant portability fixes in #949. I don't mind which one to proceed with, but I just want to preserve the work of the previous closed PRs as I believe not all of the patches are part of the currently open set of PRs.
Additionally, this implements my proposal to split the building of the native libs into a different job matrix than the Python distribution building.

I am not sure if current versions of bitsandbytes depend on pthread but attempt #220 imports pthread-win32 as pthread isn’t supported on windows either.

For context this is the original commit:

Thanks a lot @wkpark
I am very much in favor of this PR as it currently
1- tests bnb compilation on windowns AND ubuntu on each commit on main + on each PR to make sure future PRs will not break bnb compilation
2- makes bnb compilation easier through Cmake
3- Once we merge this PR #876 should be closed
I will let @Titus-von-Koeller give a final decision on this - I assume the classic make xxx commands will still work - @wkpark once this gets merged, would you be happy to update the way we build bnb on our docker images to leverage CMake ? We do it exactly here: https:/huggingface/peft/blob/189a9a666dc90f335b6a4db77f4b856b6a8bbdfd/docker/peft-gpu-bnb-source/Dockerfile#L60 and here: https:/huggingface/peft/blob/189a9a666dc90f335b6a4db77f4b856b6a8bbdfd/docker/peft-gpu-bnb-latest/Dockerfile#L60

PR #220 by @niclimcy and PR #229 by @acpopescu are almost identical with PR #788 @Jamezo97
(Some PRs have already been closed.)
so I've cleaned up some unrelated stuff, cherry picked/partial squashed and extracted into minimal subsets of several PRs.

pthread vs std::thread -> make pthread optional. : win32 fix PR
do not rename pythonInterface.cpp : add cmake option
AVX related : win32 fix PR
cmake -> extract PR
lib detection -> extract PR
documents and trivial fixes -> drop

Thanks @wkpark for your great work ! as #876 being merged could you re-enable windows build in the workflow + rebase with main?

.github/workflows/cmake.yml

younesbelkada · 2024-02-01T03:18:39Z

@wkpark could you also update the documentation and the main reamde with instructions on how to build bnb with windows?

@wkpark Thanks a lot ! let me know if you need any help for #908 (comment) - could you just share how to build bnb from source using a windows machine, i.e, the exact commands and I'll push on your branch

wkpark · 2024-02-01T06:10:48Z

For the docs you can start filling some content here: https:/TimDettmers/bitsandbytes/blob/main/docs/source/installation.mdx

this is just a note for windows user who wanted to build from source.

git clone
cmake -B build -DBUILD_CUDA=ON -S .
cmake --build build --config Release
python -m build --wheel (build python wheel using build module.) then you can get dist/*.whl

younesbelkada · 2024-02-01T07:17:28Z

@wkpark check out https://moon-ci-docs.huggingface.co/docs/bitsandbytes/pr_908/en/installation now there is a nice table that showcases how to install bnb:

Should have used targets from https://cmake.org/cmake/help/latest/module/FindCUDAToolkit.html . This now assumes that the libraries are on the library search path

All of this will be tweaked soon anyway, don't worry – see #949 for the follow-up.
