Proposed fix: [faiss-cpu] pip install tries to build from source and fails with "error: command 'swig' failed" when no wheel exists for the Python version
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Use a faiss-cpu release with wheels for your Python (>=1.9.0.post1 for 3.13, >=1.12.0 for 3.14) or a Python version covered by the pinned release; avoid building from source.
Fix: Install a faiss-cpu release with a wheel for your Python [evidence: released_fix]
Applies when: Source-build failures
Steps:
1. python -V
2. pip install 'faiss-cpu>=1.9.0.post1' (3.13) or 'faiss-cpu>=1.12.0' (3.14)
3. If a dependency pins an old faiss-cpu, relax the pin or use a matching Python
Expected: pip installs a binary wheel without SWIG.
