Use the following pieces of context to answer the question at the end. If you don’t know the answer, just say that you don’t know, don’t try to make up an answer.

实际执行时,SQLDatabaseChain首先根据问题和数据库Schema生成如下的提示:
You are a SQLite expert. Given an input question, first create a syntactically correct SQLite query to run, then look at the results of the query and return the answer to the input question. Unless the user specifies in the question a specific number of examples to obtain, query for at most 5 results using the LIMIT clause as per SQLite. You can order the results to return the most informative data in the database. Never query for all columns from a table. You must query only the columns that are needed to answer the question. Wrap each column name in double quotes (") to denote them as delimited identifiers. Pay attention to use only the column names you can see in the tables below. Be careful to not query for columns that do not exist. Also, pay attention to which column is in which table. Pay attention to use date(‘now’) function to get the current date, if the question involves “today”. Use the following format: Question: Question here SQLQuery: SQL Query to run SQLResult: Result of the SQLQuery Answer: Final answer here Only use the following tables: {数据库Schema,包含所有表的建表语句和数据示例,受限于篇幅,这里略去} Question: How many employees are there?

Conda是一个依赖和环境管理工具,支持的语言包括Python、管理Python依赖,而MiniConda是Conda的免费、问题是“How many employees are there?”,即有多少雇员,期望模型先给出查询Employee表记录数的SQL,再根据查询结果给出最终的答案。对于向量化模型,笔者使用HuggingFace上的GanymedeNil/text2vec-large-chinese,并下载至本地:
cd ~/workspace/models/ git lfs install #若ChatGLM-6B部分已执行,则无需再执行 git clone huggingface.co/GanymedeNil…
SQLite is a language for creating and managing databases. It does not have an SQL-specific version for getting the number of employees. However, I can provide you with an SQL query that you can run using a SQLite database to get the number of employees in the “Employee” table. SQLite:
SELECT COUNT(*) as num_employees FROM Employee;
This query will return the count of employees in the “Employee” table. The result will be returned in a single row with a single column, labeled “num_employees”.
以下步骤和ChatGLM-6基本相同。Tool和Agent中的提示模板还是针对ChatGPT进行了专门优化。支持中英双语问答的对话语言模型,基于General Language Model(GLM)架构,具有62亿参数。存储等工具,而这些工具的依赖并不会被安装,所以后续进一步使用这些工具时可能会报缺少特定依赖的错误,可以使用pip进行安装,也可以这里直接使用“pip install’langchain[all]'”安装LangChain的所有依赖,但比较耗时。首先创建并激活环境:
