annoylib#

Compiled with GCC/Clang(Using 512-bit AVX instructions).

High-performance approximate nearest neighbours (Annoy) C++ core.

This module is a low-level backend (annoylib). It exposes the C++-powered Annoy type. For day-to-day work, prefer a higher-level Python wrapper (if your project provides one):

>>> from annoy import Annoy, AnnoyIndex

If your project ships a higher-level wrapper, it may re-export the same type under a different module path (for example, annoy):

>>> from scikitplot.cexternals._annoy import Annoy, AnnoyIndex
>>> from scikitplot.annoy import Annoy, AnnoyIndex, Index

Notes

  • 32-bit integer (4 bytes) can store values from −2^31 to 2^31−1, roughly ±2 billion.

  • 64-bit integer (8 bytes) can store values from −2^63 to 2^63−1, roughly ±9 quintillion.
