#5 crewAI: prepare-se para a Rebelião das Máquinas!
22 min readJun 2, 2024
TL;DR: No quinto e último episódio da nossa série, apresento o Agente de Restaurante, o mais novo membro da nossa equipe. Utilizaremos o PGSearchTool para realizar buscas em um banco de dados PostgreSQL.
Nesta série de artigos, exploramos a criação de ferramentas personalizadas e a busca de conteúdo em uma API REST, na internet e em arquivos JSON. Agora, para completar a série, vamos utilizar o PGSearchTool, uma ferramenta que permite realizar buscas semânticas em tabelas de banco de dados. Essa ferramenta também utiliza a tecnologia RAG, conforme abordado no artigo #4 desta série.
Neste exemplo, utilizaremos um serviço de banco de dados gratuito disponibilizado pela Aiven (https://aiven.io/). Não entrarei em detalhes sobre o site, mas, em resumo, ele oferece um banco de dados PostgreSQL para testes. Após a configuração, é fornecida uma URL para que possamos conectar ao banco de dados.
Lembre-se, o objetivo aqui é apenas demonstrar o uso da ferramenta. A aplicação que faremos com ela poderia, sem problema, ser realizada com outras ferramentas.
Para o nosso exercício, criei uma tabela no banco de dados com a estrutura mostrada abaixo e inseri 10 restaurantes para cada cidade.
CREATE TABLE public.restaurantes (
id serial4 NOT NULL,
nome varchar(255) NOT NULL,
cidade varchar(100) NOT NULL,
tipo_culinaria varchar(100) NULL,
avaliacao numeric(2, 1) NULL,
CONSTRAINT restaurantes_pkey PRIMARY KEY (id)
);INSERT INTO restaurantes (nome, cidade, tipo_culinaria, avaliacao) VALUES
('Belcanto', 'Lisboa', 'Portuguesa', 4.8),
('A Cevicheria', 'Lisboa', 'Peruana', 4.7),
('Ramiro', 'Lisboa', 'Frutos do Mar', 4.6),
('Bistro 100 Maneiras', 'Lisboa', 'Europeia Contemporânea', 4.7),
('Taberna da Rua das Flores', 'Lisboa', 'Portuguesa', 4.5),
('Alma', 'Lisboa', 'Portuguesa Contemporânea', 4.7),
('Cantinho do Avillez', 'Lisboa', 'Portuguesa Contemporânea', 4.6),
('Cervejaria Trindade', 'Lisboa', 'Portuguesa', 4.3),
('Time Out Market', 'Lisboa', 'Vários', 4.4),
('Sea Me', 'Lisboa', 'Peixes e Frutos do Mar', 4.5);Para gerar dados para as demais cidades, você pode usar um prompt similar a esse:
Faça uma busca na internet e me traga pelo menos 10 restaurantes para cada cidade da lista abaixo:
— Lisboa
— Valladolid
— Lourdes
— Nice
— Marseille
— Saragoça
— MadridO resultado tem que ser em forma de INSERT na tabela chamada ‘restaurantes’ que tem as colunas: id, nome, cidade, tipo_culinaria e avaliacao.
Nosso novo agente, chamado “Agente de Restaurantes”, terá a tarefa de buscar sugestões de restaurantes para cada cidade usando a ferramenta PGSearchTool.
A configuração da ferramenta é bastante semelhante ao processo que utilizamos para configurar a JSONSearchTool. Esse conhecimento facilitou a implementação do novo Agente de Restaurantes, garantindo uma integração suave com a PGSearchTool para buscar sugestões de restaurantes por cidade.
pg_tool = PGSearchTool(
db_uri='postgres://<DB_PASSWORD>@pg-crewai-lucianosantosborges-crewai.j.aivencloud.com:<PORT>/<DB_NAME>?sslmode=require', table_name='restaurantes',
config={
"llm": {
"provider": "ollama",
"config": {
"model": "llama3"
},
},
"embedder": {
"provider": "google",
"config": {
"model": "models/embedding-001",
"task_type": "retrieval_document"
}
}
}
)Como o PGSearchTool ainda não está disponível no pacote crewai_tools, foi necessário instalar o pacote utilizando o código abaixo:
!pip install --q 'embedchain[postgres]'E fazer a importação conforme a documentação:
from crewai_tools import PGSearchToolUma vez que a ferramenta já está criada e tudo configurado para sua execução, vamos avançar para a criação do nosso agente e a definição de sua tarefa. Este processo será semelhante ao que já realizamos anteriormente, garantindo a integração perfeita com as demais ferramentas que desenvolvemos ao longo da série.
restaurant_agent = Agent(
role="Agente de Restaurante",
goal="Ajudar os clientes com indicações de restaurantes ao longo do itinerário da viagem "
"fornecido pelo Agente de Viagem.",
backstory="ourmet e entusiasta da culinária, o agente de restaurante possui um profundo "
"conhecimento dos melhores lugares para comer. Ele usa essa paixão para sugerir "
"experiências gastronômicas que irão satisfazer todos os paladares.",
allow_delegation=False,
verbose=True,
llm=llama3
)get_restaurants_task = Task(
description="Obter restaurantes para cada cidade no itinerário fornecido."
"Cidades duplicadas devem ser desconsideradas.",
expected_output="Lista dos nomes e avaliações dos 5 restaurantes mais bem avaliados para cada cidade.",
tools=[pg_tool],
agent=restaurant_agent,
context=[load_trip_task],
error_handling="Em caso de erro, registrar a falha e notificar o operador responsável."
)Para finalizar, vamos adicionar o agente e a tarefa na crew:
trip_crew = Crew(
agents=[trip_agent, route_agent, tourist_guide_agent, hosting_agent, restaurant_agent],
tasks=[load_trip_task, calculate_distance_and_travel_time_task, get_tourist_attractions_task, get_hotels_task, get_restaurants_task, consolidate_trip_task],
process=Process.sequential,
verbose=True
)Assim como fizemos no artigo anterior, limitei a quantidade máxima de iterações (max_iter=15) e requisições por minuto (max_rpm=300) de todos os agentes para garantir que todas as atividades fossem executadas de maneira eficiente. Essa abordagem ajuda a evitar sobrecargas e a manter o desempenho ideal do sistema.
O grande desafio está em realizar esse tuning e encontrar os valores ideais para o número máximo de iterações e requisições por minuto. Esse processo é crucial para garantir que todas as atividades sejam executadas de forma eficiente, sem sobrecarregar o sistema. Ajustar esses parâmetros requer testes cuidadosos e ajustes contínuos, pois cada ambiente pode ter suas particularidades e demandas específicas.
Abaixo está o resultado final de uma das rodadas concluídas com sucesso, sem exceder o número de tokens.
