Facebook sync (May 2019) + relicense (#838) Changelog: - changed license: BSD+Patents -> MIT - propagates exceptions raised in sub-indexes of IndexShards and IndexReplicas - support for searching several inverted lists in parallel (parallel_mode != 0) - better support for PQ codes where nbit != 8 or 16 - IVFSpectralHash implementation: spectral hash codes inside an IVF - 6-bit per component scalar quantizer (4 and 8 bit were already supported) - combinations of inverted lists: HStackInvertedLists and VStackInvertedLists - configurable number of threads for OnDiskInvertedLists prefetching (including 0=no prefetch) - more test and demo code compatible with Python 3 (print with parentheses) - refactored benchmark code: data loading is now in a single file

Facebook sync (Mar 2019) (#756) Facebook sync (Mar 2019) - MatrixStats object - option to round coordinates during k-means optimization - alternative option for search in HNSW - moved stats and imbalance_factor of IndexIVF to InvertedLists object - range search for IVFScalarQuantizer - direct unit8 codec in ScalarQuantizer - renamed IndexProxy to IndexReplicas and moved to main Faiss - 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 throw exceptions instead of terminating on an assertion - support for renaming an ondisk invertedlists - interrupt computations with ctrl-C in python
