Faiss GPU

Faiss GPU (Facebook AI Similarity Search) is a library for efficient similarity search and clustering of dense vectors, with a strong focus on high performance through GPU acceleration. The `faiss-gpu` package on PyPI provides Python bindings designed for NVIDIA GPUs. While the upstream Faiss library and its associated wheel-building projects have progressed to significantly newer versions (e.g., v1.9.x or v1.13.x), the current version of `faiss-gpu` directly available on PyPI is `1.7.2` (as of early 2022). This implies that many recent features, bug fixes, and performance improvements from more current Faiss releases are not present in the PyPI `faiss-gpu` package.
