Faiss python documentation. Faiss is written in C++ with complete wrappers for Python (versions 2 and 3). Jul 27, 2023 · The Python version of Faiss contains just wrappers to the C++ functions (generated with Swig), so the Python functions match the C++ ones. Build backend uses scikit-build-core. Support various build options for Dec 13, 2025 · Python Wrappers Relevant source files Purpose and Scope This page documents the NumPy-friendly Python wrapper layer that makes Faiss indexes and methods convenient to use from Python with NumPy arrays. It Faiss is a library for efficient similarity search and clustering of dense vectors. Faiss Faiss is a library for efficient similarity search and clustering of dense vectors. See The FAISS Library paper. Default BLAS backend is OpenBLAS on Linux/Windows and the Accelerate framework on macOS. Faiss is written in C++ with complete wrappers for Python/numpy. Faiss is written in C++ with complete wrappers for Python. It also includes supporting code for evaluation and parameter tuning. For the underlying SWIG binding generation mechanism, see SWIG Feb 24, 2025 · Faiss is a library for efficient similarity search and clustering of dense vectors. void sync_l2norms() void clear_l2norms() virtual Faiss comes with precompiled libraries for Anaconda in Python, see faiss-cpu, faiss-gpu and faiss-gpu-cuvs. The wrappers add automatic array conversion, type checking, and reference management on top of the SWIG-generated bindings. These tutorials cover the spectrum from basic brute-force search Jul 27, 2023 · The Python version of Faiss contains just wrappers to the C++ functions (generated with Swig), so the Python functions match the C++ ones. Some of the most useful algorithms are implemented on Public Functions inline explicit IndexFlatL2(idx_t d) Parameters: d – dimensionality of the input vectors inline IndexFlatL2() virtual FlatCodesDistanceComputer *get_FlatCodesDistanceComputer() const override a FlatCodesDistanceComputer offers a distance_to_code method The default implementation explicitly decodes the vector with sa_decode. Faiss Faiss is a library for efficient similarity search and clustering of dense vectors. Some if its most useful algorithms are implemented on the GPU. It Facebook AI Similarity Search (FAISS) is a library for efficient similarity search and clustering of dense vectors. Faiss contains algorithms that search in sets of vectors of any size, and also contains supporting code for evaluation and parameter tuning. faiss Overview This repository provides CI scripts to build wheel packages for the faiss library. Faiss comes with precompiled libraries for Anaconda in Python, see faiss-cpu, faiss-gpu and faiss-gpu-cuvs. From their wiki: Most examples are in Python for brievity, but the C++ API is exactly the same, so the translation for one to the other is trivial most of the times. It also contains supporting code for evaluation and parameter tuning. Builds wheels with cibuildwheel. The library is mostly implemented in C++, the only dependency is a BLAS implementation.
