# sie-wheels

Prebuilt Python wheels that the [Superlinked Inference Engine](https://github.com/superlinked/sie) build pins by exact URL and sha256. They are unmodified copies of upstream builds, kept here so that CI and image builds do not depend on GitHub release downloads.

Files are never changed after upload. Consumers reference a repository revision (`/resolve/<commit>/<file>`), so a later upload cannot change what an existing lockfile installs, and the lockfile records each file's sha256.

## Files

| File | Upstream | sha256 |
|---|---|---|
| `flash_attn-2.7.4+cu129torch2.9-cp312-cp312-manylinux_2_24_x86_64.manylinux_2_28_x86_64.whl` | [mjun0812/flash-attention-prebuild-wheels v0.7.11](https://github.com/mjun0812/flash-attention-prebuild-wheels/releases/tag/v0.7.11), published 2026-01-17: [flash-attention](https://github.com/Dao-AILab/flash-attention) 2.7.4 built for torch 2.9 and CUDA 12.9, CPython 3.12, manylinux x86_64 | `0a8f6219e61f8ff923cfd2cdad105d95a66106a6c9e754486d778c3a25e7707f` |

## Adding a wheel

1. Download the upstream file and record its sha256.
2. Upload it unchanged, together with an updated table above, in one commit.
3. Reference `https://huggingface.co/superlinked/sie-wheels/resolve/<commit>/<file>` and let the lockfile record the hash.
