Zilliz Cloud 是一个基于 LF AI Milvus® 的全托管云服务,
本笔记本演示了如何使用与 Zilliz Cloud 托管向量数据库相关的功能。 您需要通过 pip install -qU langchain-community 安装 langchain-community 才能使用此集成。 要运行此程序,您应该有一个正在运行的 Zilliz Cloud 实例。这是安装说明
pip install -qU  pymilvus
我们希望使用OpenAIEmbeddings,所以我们必须获取OpenAI API密钥。
import getpass
import os

if "OPENAI_API_KEY" not in os.environ:
    os.environ["OPENAI_API_KEY"] = getpass.getpass("OpenAI API Key:")
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: "*********"
ZILLIZ_CLOUD_API_KEY = ""  # example: "*********" (for serverless clusters which can be used as replacements for user and password)

docs = vector_db.similarity_search(query)
docs[0].page_content
'Tonight. I call on the Senate to: Pass the Freedom to Vote Act. Pass the John Lewis Voting Rights Act. And while you’re at it, pass the Disclose Act so Americans can know who is funding our elections. \n\nTonight, I’d like to honor someone who has dedicated his life to serve this country: Justice Stephen Breyer—an Army veteran, Constitutional scholar, and retiring Justice of the United States Supreme Court. Justice Breyer, thank you for your service. \n\nOne of the most serious constitutional responsibilities a President has is nominating someone to serve on the United States Supreme Court. \n\nAnd I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson. One of our nation’s top legal minds, who will continue Justice Breyer’s legacy of excellence.'
