| # CUDA Extension Wheelhouse |
|
|
| Prebuilt Python **wheels** for CUDA / PyTorch extensions |
| (`cumesh`, `flash_attn`, `flex_gemm`, `natten`, `nvdiffrast`, `nvdiffrec_render`, |
| `o_voxel`). Compiling these from source dominates install time — often **hours** |
| on a single machine. This dataset is a shared cache so machines and CI can |
| **build once, then reuse the wheel** and skip the compile entirely. |
|
|
| Built for GPU archs `sm75`, `sm80`, `sm89`, `sm120` against `torch2.7`/`torch2.9` |
| (CUDA 12.8), for CPython `cp310` and `cp312`. |
|
|
| ## Why a wheel can't just be cached by filename |
|
|
| A compiled-extension wheel's runnability depends on **four** axes, but the wheel |
| filename only encodes **two** (dist name + Python ABI tag). The other two — the |
| **GPU compute architecture** and the **torch version it was ABI-linked against** — |
| are invisible in the name. A wheel built for `sm120` / `torch2.9` installs fine on |
| `sm89` / `torch2.7` and then dies at the first kernel launch |
| (`no kernel image available`). So wheels are stored under a path that carries |
| arch + torch. |
|
|
| ## Layout |
|
|
| ``` |
| <package>/sm<arch>/torch<major.minor>-cu<cuda>/<wheel>.whl |
| ``` |
|
|
| Examples: |
|
|
| ``` |
| flash_attn/sm89/torch2.9-cu128/flash_attn-2.8.3+cu128torch2.9-cp312-cp312-linux_x86_64.whl |
| nvdiffrast/sm89/torch2.9-cu128/nvdiffrast-0.4.0-cp312-cp312-linux_x86_64.whl |
| natten/sm120/torch2.7-cu126/natten-0.21.0-cp310-cp310-linux_x86_64.whl |
| ``` |
|
|
| - `sm<arch>` — GPU compute capability of the card the wheel runs on (e.g. `sm89` |
| for Ada / RTX 40xx, `sm120` for Blackwell). Keyed off the **real GPU**, not a |
| multi-arch build list. |
| - `torch<mm>-cu<cuda>` — the torch + CUDA the extension was linked against |
| (e.g. `torch2.9-cu128`). |
| - The Python ABI tag (`cp310`, `cp312`, …) lives in the wheel filename itself. |
|
|
| ## Usage |
|
|
| Download a specific wheel: |
|
|
| ```python |
| from huggingface_hub import hf_hub_download |
| |
| path = hf_hub_download( |
| repo_id="DoctorPopi/python_wheelhouse", |
| repo_type="dataset", |
| filename="flash_attn/sm89/torch2.9-cu128/flash_attn-2.8.3+cu128torch2.9-cp312-cp312-linux_x86_64.whl", |
| ) |
| # then: pip install --force-reinstall --no-deps <path> |
| ``` |
|
|
| > Install compiled wheels with `--force-reinstall --no-deps`: several declare an |
| > unpinned `torch` requirement and a bare reinstall would clobber the env's pinned |
| > torch, breaking every other C-extension built against the original ABI. |
|
|
| ## Licensing |
|
|
| Each wheel is a build of its **upstream project** and remains under that project's |
| own license (e.g. natten, nvdiffrast, flash-attention each have their own terms). |
| This dataset only redistributes compiled artifacts for convenience; refer to each |
| package's upstream repository for license terms. |
