简介
在这里，我们将创建一个代理团队，利用 SQL 数据库中的数据回答复杂的问题。
在团队中，代理可以看作是被分配了特定专长和职责的团队成员。这些代理承担着不同的角色，如 “研究员”、“撰稿人 ”或 “客户支持”，每个角色都在实现团队的集体目标方面发挥着重要作用。在此，我们将采用以下方法：
- 将代理与 SQL 数据库连接起来
- 为编写 SQL 查询设置代理工具
- 建立一个使用 Llama 3 分析数据的代理团队
将 SQL 与代理集成
设想授予人工智能直接与机密数据交互的权限。这就是将代理与 SQL 数据库连接起来的结果。这是一种高超的变通方法，它超越了传统的基于文本的 RAG（检索-增强生成）方法。
是什么让它如此出色？
利用 SQL，人工智能可以毫不费力地过滤和搜索数据，具有无与伦比的灵活性。然后，人工智能会根据从数据库中检索到的准确结果制作响应，确保精确度和准确性。
为什么选择 SQL 数据库？
- 久经考验：SQL 数据库是许多应用程序的支柱。
- 可靠、快速： 它们可以快速安全地处理大量数据。
- 我们的数据已经存在： 许多企业已经将重要信息存储在 SQL 数据库中。
传统的 RAG 使用文本块来表示上下文。但 SQL 方法与此不同。它具有以下优势：
- 灵活搜索：人工智能可以使用 SQL 进行过滤，准确找到所需的信息
- 更好的答案： 人工智能根据精确的数据结果生成回复
- 可扩展性： SQL 数据库可轻松处理海量数据
- 数据完整性： SQL 可保持数据的一致性和连接性
所需技术组件
CrewAI ：
CrewAI 是一个创新的开源框架，允许用户利用智能代理的协作能力。与传统的聊天机器人不同，这些代理拥有协作、交换信息的能力，并能作为一个有凝聚力的团队处理复杂的任务。
设想一下一群专家和谐合作的场景。每个成员都拥有独特的专长和知识，但他们的沟通能力和责任分配能力使他们取得了超越个人能力的成就。CrewAI 将这一协作原则应用于人工智能领域。在这一框架内，各个具有独特优势和局限性的代理在 CrewAI 的协调下进行互动，最终实现共同目标。
GROQ：
Groq 是一个开创性的平台，无缝集成了最先进的硬件和软件组件，以其出色的计算速度、卓越的质量和显著的能效而闻名。Groq产品的核心是LPU™推理引擎。
LPU Inference Engine 也称为 Language Processing Unit™（语言处理单元），是一种结合了先进硬件和软件元素的先进系统。这一革命性的端到端处理单元旨在提供无与伦比的计算速度、卓越的质量和超高的能效。LPU 推理引擎擅长为计算密集型应用提供快速推理，尤其是人工智能语言应用等顺序组件，包括令人印象深刻的大型语言模型（LLM）。
在这里，我们将使用 Llama3 70B 来驱动我们的代理。
SQL Agent 的实施细节
涉及步骤：
- 创建与数据库交互的工具
- 创建数据库开发人员代理，以构建和执行 SQL 查询。
- 创建数据分析代理，分析数据库数据响应并编写详细响应。
- 创建编辑器代理，根据分析结果撰写执行摘要。
- 创建任务，根据用户查询提取数据，分析提取的数据，并根据提供的分析撰写报告。
- 使用 Llama3-70B 作为 LLM
代码实现
在 google colab 中使用高内存 CPU 实现。
安装所需库函数
!pip install -qU langchain-core==0.2.90.2.9
!pip install -qU langchain-community==0.2.5
!pip install -qU 'crewai[tools]'==0.32.0
!pip install -qU langchain-groq==0.1.5
导入所需依赖项

from dataclasses import asdict, dataclass
from datetime import datetime, timezone
from pathlib import Path
from textwrap import dedent
from typing import Any, Dict, List, Tuple, Union
import pandas as pd

from langchain.schema import AgentFinish
from langchain.schema.output import LLMResult
from langchain_community.tools.sql_database.tool import (
InfoSQLDatabaseTool,

)
from langchain_community.utilities.sql_database import SQLDatabase
from langchain_core.callbacks.base import BaseCallbackHandler
from langchain_core.prompts import ChatPromptTemplate
from langchain_groq import ChatGroq
from google.colab import userdata
os.environ["GROQ_API_KEY"] = userdata.get("GROQ_API_KEY")
数据
df = pd.read_csv("ds-salaries.csv")"ds-salaries.csv")
df.head()
将数据帧保存到 SQLite 数据库中
connection = sqlite3.connect("salaries.db")"salaries.db")
df.to_sql(name="salaries", con=connection)设置 LLM
llm = ChatGroq(
temperature=0,0,
#model_name="llama3-70b-8192",
model_name="mixtral-8x7b-32768",
callbacks=[LLMCallbackHandler(Path("prompts.jsonl"))],
)
设置日志记录器： 该回调将把来自 Llama 3 的提示和响应记录到文件中
@dataclass
class Event:
event: str
timestamp: str
text: str
def _current_time() -> str:
return datetime.now(timezone.utc).isoformat()
class LLMCallbackHandler(BaseCallbackHandler):

self, serialized: Dict[str, Any], prompts: List[str], **kwargs: Any
) -> Any:

assert len(prompts) == 1
event = Event(event="llm_start", timestamp=_current_time(), text=prompts[0])
with self.log_path.open("a", encoding="utf-8") as file:
file.write(json.dumps(asdict(event)) + "\n")
def on_llm_end(self, response: LLMResult, **kwargs: Any) -> Any:

event = Event(event="llm_end", timestamp=_current_time(), text=generation)
with self.log_path.open("a", encoding="utf-8") as file:

创建工具
这些工具将基于 langchain_community SQL 数据库工具。这些工具将使用 @tool 装饰器进行封装，以便提供给我们的 CrewAI 代理。

[2024-07-13 17:45:45][DEBUG]: == [Senior Data Analyst] Task output: The analysis of the effects on salary (in USD) based on company location, size, and employee experience is as follows:
**Company Location:**
The data shows that salaries vary significantly across different countries. The top 5 countries with the highest average salaries are:
1. United States: $124,111
2. Israel: $112,417
3. Singapore: $81,157
4. Australia: $76,419
5. Canada: $74,391
On the other hand, the bottom 5 countries with the lowest average salaries are:
1. Albania: $10,000
2. Armenia: $15,000
3. Bosnia and Herzegovina: $18,000
4. Bulgaria: $20,000
5. Croatia: $22,000
**Company Size:**
The data suggests that salaries tend to increase with company size. The average salaries for different company sizes are:
1. Large companies: $83,419
2. Medium companies: $54,391
3. Small companies: $43,419
**Employee Experience:**
The data shows that salaries tend to increase with employee experience. The average salaries for different levels of experience are:
1. Executive: $134,419
2. Senior: $83,419
3. Mid-level: $54,391
4. Entry-level: $43,419
**Interaction between Company Location and Company Size:**
The data suggests that the effect of company size on salary varies across different countries. For example, in the United States, large companies tend to pay significantly higher salaries than small companies, while in India, the difference in salaries between large and small companies is relatively small.
**Interaction between Company Location and Employee Experience:**
The data suggests that the effect of employee experience on salary varies across different countries. For example, in the United States, executives tend to earn significantly higher salaries than entry-level employees, while in India, the difference in salaries between executives and entry-level employees is relatively small.
Overall, the analysis suggests that salaries are influenced by a combination of factors, including company location, company size, and employee experience. Understanding these factors can help companies develop more effective compensation strategies to attract and retain top talent.
