Install Infinity locally using pip

Infinity, also available as a Python module, eliminates the need for a separate back-end server and all the complex communication settings. Using pip install and import infinity, you can quickly build a local AI application in Python, leveraging the world's fastest and the most powerful RAG database:

  1. Install Infinity as a module:
    pip install infinity-sdk==0.2.1.dev5
  2. Use Infinity to conduct a KNN search:
    import infinity

    # Connect to infinity
    infinity_obj = infinity.connect("/path/to/save/to")
    db = infinity_obj.get_database("default_db")
    table = db.create_table("my_table", {"num": {"type": "integer"}, "body": {"type": "varchar"}, "vec": {"type": "vector, 4, float"}})
    table.insert([{"num": 1, "body": "unnecessary and harmful", "vec": [1.0, 1.2, 0.8, 0.9]}])
    table.insert([{"num": 2, "body": "Office for Harmful Blooms", "vec": [4.0, 4.2, 4.3, 4.5]}])
    res = table.output(["*"]).knn("vec", [3.0, 2.8, 2.7, 3.1], "float", "ip", 2).to_pl()
    print(res)

Deploy Infinity as a separate server
