…xcore
Nightly run 34567455178/job 103162417768 (12.2.2, 3.11, amd64,
ubuntu22.04, v100, earliest-driver, latest-deps) failed 21 cvxpy
integration tests with:
ImportError: cannot import name '_cvxcore' from 'cvxpy.cvxcore.python'
despite `pip wheel -w dist .` reporting "Successfully built cvxpy" in
~24s. This is a distinct failure mode from #1747, which fails loudly
with "error: ... g++" when no compiler is present -- here the build
reports success but never actually compiles the native extension.
Root cause: cvxpy's own setup.py has a silent escape hatch --
`ext_modules=extensions if "PYODIDE" not in os.environ else []` --
that produces a pure-Python ("py3-none-any") wheel with no
`_cvxcore*.so` and no error whenever that condition is hit. This was
reproduced locally: building with PYODIDE set in the environment
yields "Successfully built cvxpy" in seconds, a wheel with no
_cvxcore, and the exact ImportError from the nightly log once
installed. The specific trigger in the CI container is unconfirmed,
but the underlying gap is real regardless of trigger: nothing in the
script verified the build actually produced a working extension.
Fix ci/thirdparty-testing/run_cvxpy_tests.sh to:
- Install build-essential (g++) up front if missing, so a plain
missing-compiler case (as in #1747) doesn't even get this far.
- Immediately after `pip wheel`, inspect the built wheel for a
`_cvxcore*.so` member and fail with a clear diagnostic if it's
absent, instead of silently proceeding to a confusing downstream
test failure.
- After install, do a belt-and-braces
`from cvxpy.cvxcore.python.cppbackend import build_matrix` import
check and fail loudly with the captured traceback if it fails.
Verified locally: a normal `pip wheel` build produces a wheel
containing `_cvxcore.cpython-311-x86_64-linux-gnu.so`, which the new
check accepts. Forcing PYODIDE=1 during the build reproduces both the
missing .so and, once installed, the identical ImportError from the
nightly log -- confirming the new wheel-content check would have
caught this before ever reaching pytest.

site:pip.pypa.io pip install same version already installed force-reinstall local wheel
💡 Result:
To force the installation of a local wheel file even when the same version is already installed, you can use the --force-reinstall flag with the pip install command [1][2]. The command syntax is: pip install --force-reinstall /path/to/your/package.whl Key points regarding this behavior: - Force Reinstall: The --force-reinstall option instructs pip to uninstall the existing version of the package and reinstall it from the specified source, even if the installed version is already up-to-date [1][3]. - Local Wheel: When providing a direct path to a local.whl file, pip will use that specific archive for the installation [2]. - Important Caveat: Be aware that in some contexts, using --force-reinstall can implicitly trigger an upgrade to the latest available version if the package is not being installed from a local file, though when pointing directly to a local wheel, pip typically processes the specified file [4]. To ensure you are installing only the local wheel and ignoring external indexes, you can combine this with the --no-index flag [5][6]. Example of a fully isolated installation from a local wheel: pip install --force-reinstall --no-index /path/to/your/package.whl If you encounter issues with cached versions being used, you can also manage the pip cache using the pip cache command, or ensure you are pointing to the explicit file path as shown above [7].

Force installation of the built wheel before the import check.
If the same cvxpy version is already installed, pip install may keep that distribution. The import check may then load the previous native extension instead of the wheel built in this job. Add --force-reinstall.

The previous commit's PYODIDE theory was unconfirmed guesswork (no PYODIDE env var appears anywhere in the failing CI log). Reproducing the exact failing commit showed the built wheel is fine and contains a working _cvxcore.so. The actual cause: the script runs pytest from inside the freshly cloned './cvxpy' directory, whose own root is named 'cvxpy' and contains a 'cvxpy/' package subdirectory (the uncompiled source tree). Python puts cwd first on sys.path, so 'import cvxpy' from in there resolves to the local source tree instead of the properly built and pip-installed wheel -- reproducing the exact "ImportError: cannot import name '_cvxcore'" traceback path seen in the nightly log, regardless of whether the extension built correctly. Fix: leave the clone directory before importing cvxpy or running pytest, and invoke pytest with --pyargs (module path) instead of a filesystem path, since a filesystem path makes pytest re-insert the clone root onto sys.path via its own rootdir walk-up even with cwd fixed.

Canonicalize RAPIDS_TESTS_DIR before popd.
If CI sets a relative RAPIDS_TESTS_DIR, mkdir creates it under the clone. After popd, pytest resolves the same relative path from the parent directory, so the JUnit report can use a different directory or fail to be created.

Nightly run 34567455178 (
wheel-tests-cuopt / 12.2.2, 3.11, amd64, ubuntu22.04, v100, earliest-driver, latest-deps) failed 21 cvxpy integration tests with:Root cause (verified by reproduction, not guesswork)
This is a
cwdimport-shadowing bug inrun_cvxpy_tests.sh, not a build problem.ci/thirdparty-testing/run_cvxpy_tests.shclones cvxpy into./cvxpy,pushds into it, builds and installs the wheel, and then runs pytest from inside that same directory, against./cvxpy/tests/test_conic_solvers.py. The clone's own root directory is namedcvxpyand contains acvxpy/package subdirectory (the uncompiled source tree). Python puts the current working directory first onsys.path, soimport cvxpyrun from inside the clone resolves to that local, uncompiled source tree instead of the properly built and pip-installed wheel — and the local source tree has no compiled_cvxcore*.sositting in it (that file only exists inside the built wheel).I reproduced this exactly: checked out cvxpy at the same commit as the failing run, built and installed a wheel with
_cvxcore.soconfirmed present and importable — then simply changed the working directory to the clone root and hit the identicalImportError: cannot import name '_cvxcore' from 'cvxpy.cvxcore.python' (.../cvxpy/cvxpy/cvxcore/python/__init__.py)traceback (note the doublecvxpy/cvxpypath, matching the nightly log exactly).I initially suspected cvxpy's
setup.pyPYODIDEescape hatch (ext_modules=extensions if "PYODIDE" not in os.environ else []), since forcing that env var reproduces the same symptom. That was a red herring —PYODIDEnever appears anywhere in the actual failing CI log, and the CI-built wheel filename (cvxpy-*-cp311-cp311-linux_x86_64.whl) is platform-specific, meaning the extension was in fact compiled. The real trigger is purely the working directory at test time.Fix
ci/thirdparty-testing/run_cvxpy_tests.sh:build-essential(g++) up front if missing, covering the separate, already-tracked thirdparty cvxpy: build fails on oldest-deps/arm64 nightly configs — no wheel and no g++ in container #1747 failure mode (build fails loudly with no compiler)._cvxcore*.somember and fail loudly with a clear message if not (defense in depth).popdout of the clone directory before importing cvxpy or running pytest, so cwd no longer shadows the installed package.--pyargs cvxpy.tests.test_conic_solversinstead of a filesystem path to the test file. This matters even after fixing cwd: pytest resolves a filesystem path by walking up through__init__.pyancestors to find a "rootdir" and inserts that ontosys.pathtoo — for cvxpy that walk lands back on the clone root, silently reintroducing the exact same shadowing bug.--pyargsresolves the test module through the normal Python import system against the installed package instead, sidestepping the rootdir walk entirely.python -c "from cvxpy.cvxcore.python.cppbackend import build_matrix"import check right after leaving the clone, so a genuinely broken extension still fails fast with a clear message.Test plan
