PyVectorDB

Simple Wrapper for Vector Database in Python which support CRUD and retrieve by distance.

Installation

pip install pyvectordb

Usage Example

PGVector

PGvector is an extension for PostgreSQL that allows the storage, indexing, and querying of vector embeddings. It is designed to support vector similarity search, which is useful in machine learning applications like natural language processing, image recognition, and recommendation systems. By storing vector embeddings as a data type, PGvector enables efficient similarity searches using distance metrics such as cosine similarity, Euclidean distance, inner product, etc.

import os
from pyvectordb import PostgresVector, Vector
from pyvectordb.distance_function import DistanceFunction

v = Vector(
    embedding=[2, 2, 1]
)

print("VECTOR", v)

pgv = PostgresVector(
    db_user=os.getenv("DB_USER"),
    db_password=os.getenv("DB_PASSWORD"),
    db_host=os.getenv("DB_HOST"),
    db_port=os.getenv("DB_PORT"),
    db_name=os.getenv("DB_NAME"),
)

new_v = pgv.create_vector(v)
print("CREATE_VECTOR", new_v)

new_v = pgv.read_vector(new_v.id)
print("READ_VECTOR", new_v)

new_v = pgv.update_vector(new_v)
print("UPDATE_VECTOR", new_v)

for x in pgv.get_neighbor_vectors(v, 5, DistanceFunction.L2_DISTANCE):
    print(f"{x}")

pgv.delete_vector(new_v.id)
print("DELETE_VECTOR")
