PyPI's scikit-learn-intelex wheel is Apache-2.0 and links only against the daal (oneDAL) libraries at runtime (Requires-Dist: daal==<version>, no dpctl, no SYCL/MKL NEEDED entries in its own .so files). Its setup.py already degrades to a plain arch-name DALROOT subdirectory and has CPU-only (NO_DPC, NO_DIST) build switches; upstream's own docs state it builds from source on ARM and RISC-V. This builds oneDAL from source once per version (same recipe as the daal port) and reuses it across the interpreter matrix to compile daal4py/_onedal_py_host, instead of waiting on Intel's x86_64-only wheel or a closed MKL/SYCL backend.

scikit-learn-intelex2026.1.0Compiles daal4py and the onedal pybind11/CMake module against a from-source oneDAL (CPU-only
hostiface, NO_DIST/NO_DPC). Upstream publishes no riscv64 wheel.No equivalent upstream workflow builds this exact wheel; mirrors
doc/building-from-source.rst's documented from-source recipe, which upstream states already covers ARM and RISC-V.Differs from upstream
daalport's workflow) instead of consuming Intel's x86_64-onlydaal/daal-develwheel.clang+clang-tools-extrafrom the image instead of theclang-formatPyPI package, which ships no riscv64 binary.Matrix: cp310-cp314 (no cp314t), matching upstream's own released interpreter set.
Testing
daal4py,onedal,sklearnexand callspatch_sklearn()instead of upstream's full pytest suite (GPU/distributed-only fixtures aside, this mirrorsci.yml's own smoke import).License: Nothing third-party vendored; the wheel links oneDAL (separately licensed Apache-2.0) at runtime only.
Depends on the
daalport (#2971) landing first for the runtimeRequires-Distpin to resolve; builds and tests independently since oneDAL is built from source in this workflow too.
