Changelog:
- a MatrixStats object, which reports useful statistics about a dataset;
- an option to round coordinates during k-means optimization;
- an alternative option for search in HNSW;
- moved stats() and imbalance_factor() from IndexIVF to InvertedLists object;
- range search is now available for IVFScalarQuantizer;
- support for direct uint_8 codec in ScalarQuantizer;
- renamed IndexProxy to IndexReplicas (now ;
- better support for PQ code assignment with external index;
- support for IMI2x16 (4B virtual centroids!);
- support for k = 2048 search on GPU (instead of 1024);
- most CUDA mem alloc failures now throw exceptions instead of terminating on an assertion;
- support for renaming an ondisk invertedlists;
- interrupt computations with interrupt signal (ctrl-C) in python;
- simplified build system (with
--with-cuda/--with-cuda-archoptions); - updated example Dockerfile;
- conda packages now depend on the
cudatoolkitpackages, which fixes some interferences with pytorch. Consequentially, faiss-gpu should now be installed byconda install -c pytorch faiss-gpu cudatoolkit=10.0.
