网站建设与推广的实训报告制作网站公司

一、环境准备

# 准备python环境
conda create -n opensearch
conda activate opensearch# 安装必要的包
pip install alibabacloud_tea_util
pip install alibabacloud_opensearch_util
pip install alibabacloud_credentials

二、阿里云opensearch准备

1、产品文档

新手指引：三步搭建智能问答机器人

需要购买LLM智能问答版的实例。
准备好accesskey、secret、API Key

2、准备我们的数据

3、上传文件

三、对接

1、对接文本问答
