Build and test conda packages and wheels by jharlow-intel · Pull Request #3151 · IntelPython/dpnp

jharlow-intel · 2026-11-03T17:56:24Z

Adds ci/ and .github/workflows/intel-ci.yml, which build the conda packages and wheels for Linux and Windows on every declared Python, and test each in a clean environment.

conda-recipe/ is now the only recipe: the conda-forge one that was conda-recipe-cf/. It builds against conda-forge's dpctl 0.23.0, which has no 3.10, so its Pythons start at 3.11. The Intel-channel recipe, with rattler_recipe.yaml, and conda-package.yml are removed; that workflow's Array API conformance and pybind11 examples jobs move to conda-package-cf.yml.
The dppy/label/dev uploads and their cleanup move into intel-ci.yml, for pushes to master and tags only.
Wheels build with cibuildwheel and icx 2026.2 against the dpctl wheel on PyPI, and require the oneAPI runtime wheels (dpcpp-cpp-rt, intel-sycl-rt, mkl, onemkl-sycl-*), as the PyPI wheels do. PyPI has no dpctl for 3.15 yet, so the 3.15 classifier is dropped until it does.
ci/test.py runs dpnp.tests, then dpnp.tests.tensor, against the installed package, and fails when it finds no SYCL device: the OpenCL CPU device in Actions, or a GPU with GH_CI_DEVICE=gpu.

The required checks on master come from conda-package.yml, so they need replacing with this workflow's, such as Test Linux Python 3.11, before this can merge.

Validation, with a temporary push trigger on this branch: run 41672888041 built and tested the conda packages for 3.11 and 3.15 and the wheels for 3.10 and 3.14, on Linux and Windows, and conda-package-cf.yml, pre-commit and zizmor passed. An earlier full-matrix run passed every declared Python. Not run yet: a GPU, and the uploads, which only master and tags do.

No base build to compare — ci/intel-python-ci into master

+      - name: Build and run the recipe tests
+        env:
+          PYTHON_VERSION: ${{ matrix.python }}
+        run: python ci/build.py --python "$PYTHON_VERSION" --output "$RUNNER_TEMP/output"


The conda packages and the wheels now build and test only against released dpctl (conda-forge, PyPI); the removed workflow used dppy/label/dev first. So dpnp can no longer require a dpctl dev build: dpctl>=0.24.0dev0, as #3169 sets in pyproject.toml, makes the wheel install fail, and the same in the recipe fails the conda build, as only 0.23.0 is released. Is that intended? If not, build.py --channel dppy/label/dev --channel conda-forge and the same channel in hooks.py would keep it.

This retries a suite only when it hangs. The removed workflow reran any failed suite (2 attempts, 3 for the tensor tests) and stopped a stuck tensor test after 120 s with pytest-timeout (IntelPython/dpctl#1954). Now one flaky failure fails the job and blocks the upload, and one stuck tensor test costs 20 minutes. Could it rerun on any failure, and keep --timeout=120 --timeout-method=thread for dpnp.tests.tensor?

-      - '*/dpnp_backend_c.dll'        # [win]
+  number: {{ GIT_DESCRIBE_NUMBER }}
+  ignore_run_exports:


The removed rattler_recipe.yaml ignored the mkl-dpcpp run export of mkl-devel-dpcpp, and this recipe does not. conda-forge's mkl-devel-dpcpp 2026.2.0 exports mkl-dpcpp >=2026.2.0,<2027.0a0, which pulls in onemkl-sycl-datafitting and onemkl-sycl-stats. dpnp uses neither, and these packages now go to dppy/label/dev. Could - mkl-dpcpp go back into ignore_run_exports?

+  examples:
+    name: Test examples
+    needs: linux


needs: linux waits for the whole reusable workflow, tests included: a failing Linux test now skips the examples and the Array API comment, which needed only the build before. The examples also lost 3.14t. As this workflow now repeats intel-ci.yml's builds for 3.12-3.14, could both jobs move there, with needs: build and a package every event builds (3.14t or 3.15)?

test_env keeps only KEEP and the GH_CI_* values it sets, so GH_CI_DEVICE never reaches test.py. On a GPU runner (vars.GH_CI_RUNNER) with a broken GPU driver the tests then pass on the CPU device, which ci/README.md says cannot happen. ONEAPI_DEVICE_SELECTOR is dropped too. Could both go into KEEP?

+    conda-build conda-recipe -c conda-forge --override-channels


conda_build_config.yaml now lists six Python versions, so this command builds six packages, about six times the old build time. Adding --python 3.14 here would keep it to one.

The wheels are 3.11-3.14 and 3.14t: pyproject.toml has no 3.10 classifier, as #3173 dropped 3.10. Also, the old row was required on master. Is a required check planned for intel-ci.yml, or should branch protection just drop the old Test (...) checks?

Nit: Nothing here runs benchmark.py or reads workflow, artifacts and benchmark from this file, and the JUnit reports test.py writes are not uploaded. Are they for another Intel CI service, and is ci/ copied from a shared template (it also has rattler-build, macOS and conda-recipe-cf paths dpnp does not use)? A line in ci/README.md would help either way.

 * Moved `blas`, `fft`, `lapack`, `sparse` and `vm` extensions into `dpnp/libtensor/extensions` [#3131](https://github.com/IntelPython/dpnp/pull/3131)
 * Moved the libtensor headers shipped with dpnp from `dpnp/tensor/libtensor/include` to `dpnp/libtensor/include`, and changed `dpnp.get_include` to return that directory [#3131](https://github.com/IntelPython/dpnp/pull/3131)
 * Improved performance of `dpnp.scipy.sparse.csr_matrix.sort_indices` by sorting once on a combined row and column key instead of in two passes [#3134](https://github.com/IntelPython/dpnp/pull/3134)
+* Changed the CI to build and test the conda packages of `conda-recipe` and the wheels with Intel CI (`ci/`, `.github/workflows/intel-ci.yml`); the conda packages now require `onemkl-sycl-sparse` and the wheels declare the oneAPI runtime wheels in their metadata [#3151](https://github.com/IntelPython/dpnp/pull/3151)


Nit: The dev packages from the removed recipe already required onemkl-sycl-sparse. For their users the change is that the dppy/label/dev packages are now built against conda-forge only; could the line say that instead?

Adds a ci/ directory and .github/workflows/intel-ci.yml, which build the conda packages and the wheels for every declared platform and Python and test each with ci/test.py. A pull request builds the oldest and the newest regular Python and the newest free-threaded one, and every push and tag run gets a concurrency group of its own. conda-recipe/ is now the only recipe, the conda-forge one that was conda-recipe-cf/; the Intel-channel recipe and conda-package.yml are removed. The dev uploads to anaconda.org move to intel-ci.yml, and the Array API conformance and pybind11 examples jobs to conda-package-cf.yml. The benchmarks take PyYAML from conda-forge, as PyPI has no Python 3.15 wheel for it yet. ci/build.py refuses two built packages with the same file name, which would overwrite each other in its flat output directory, and takes METADATA's line ending from its headers. conda-build records the commit each conda package came from in info/about.json, and LDFLAGS links the Linux wheels' libraries with full RELRO.
