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. Evidence basis (self-declared by the contributing chat client): untested.
