LlamaIndex Vector_Stores Integration: Hnswlib
A LlamaIndex vector store using Hnswlib, a header-only C++ HNSW implementation with python bindings.
Usage
Pre-requisite:
pip install llama-index-vector-stores-hnswlib
pip install hnswlib
A minimal example:
import hnswlib
from llama_index.vector_stores_hnswlib import HnswlibVectorStore
space = "ip" # distance function
dim = 768 # embedding dimension
hnswlib_index = hnswlib.Index(space, dim)
hnswlib_index.init_index(max_elements=10)
hnsw_vector_store = HnswlibVectorStore(hnswlib_index=index)
More examples and references
A detailed usage guede can be found in this demo notebook in the LlamaIndex docs.
