Zilliz #

Zilliz Cloud (opens in a new tab) is a fully managed service on cloud for `LF

AI

Milvus®` ,

This notebook shows how to use functionality related to the Zilliz Cloud managed vector database.

To run, you should have a `Zilliz

Cloud` instance up and running. Here are the installation instructions (opens in a new tab)

!pip install pymilvus

We want to use OpenAIEmbeddings so we have to get the OpenAI API Key.

import os
import getpass

os.environ['OPENAI_API_KEY'] = getpass.getpass('OpenAI API Key:')

# replace 
ZILLIZ_CLOUD_URI = "" # example: "https://in01-17f69c292d4a5sa.aws-us-west-2.vectordb.zillizcloud.com:19536"
ZILLIZ_CLOUD_USERNAME = ""  # example: "username"
ZILLIZ_CLOUD_PASSWORD = ""  # example: "\*\*\*\*\*\*\*\*\*"
