Génération améliorée par récupération (RAG) avec Milvus et Camel

Ce guide montre comment construire un système de génération améliorée par récupération (RAG) en utilisant CAMEL et Milvus.

Le système RAG combine un système de recherche avec un modèle génératif pour générer un nouveau texte basé sur une invite donnée. Le système récupère d'abord les documents pertinents d'un corpus à l'aide de Milvus, puis utilise un modèle génératif pour générer un nouveau texte basé sur les documents récupérés.

CAMEL est un cadre multi-agents. Milvus est la base de données vectorielles open-source la plus avancée au monde, construite pour alimenter la recherche de similarité d'intégration et les applications d'intelligence artificielle.

Dans ce carnet, nous montrons l'utilisation du module CAMEL Retrieve à la fois de manière personnalisée et de manière automatique. Nous montrerons également comment combiner AutoRetriever avec ChatAgent, et comment combiner AutoRetriever avec RolePlaying en utilisant Function Calling.

4 parties principales sont incluses :

• RAG personnalisé
• Auto RAG
• Agent unique avec Auto RAG
• Jeu de rôle avec Auto RAG

Chargement des données

Commençons par charger le document CAMEL à partir de https://arxiv.org/pdf/2303.17760.pdf. Il s'agira de notre exemple local de données.

$ pip install -U "camel-ai[all]" pymilvus

import os
import requests

os.makedirs("local_data", exist_ok=True)

url = "https://arxiv.org/pdf/2303.17760.pdf"
response = requests.get(url)
with open("local_data/camel paper.pdf", "wb") as file:
    file.write(response.content)

1. RAG personnalisé

Dans cette section, nous allons définir notre pipeline RAG personnalisé, nous prendrons VectorRetriever comme exemple. Nous définirons OpenAIEmbedding comme modèle d'intégration et MilvusStorage comme stockage.

Pour configurer l'intégration d'OpenAI, nous devons configurer OPENAI_API_KEY comme indiqué ci-dessous.

os.environ["OPENAI_API_KEY"] = "Your Key"

Importer et définir l'instance d'intégration :

from camel.embeddings import OpenAIEmbedding

embedding_instance = OpenAIEmbedding()

Importer et définir l'instance de stockage vectoriel :

from camel.storages import MilvusStorage

storage_instance = MilvusStorage(
    vector_dim=embedding_instance.get_output_dim(),
    url_and_api_key=(
        "./milvus_demo.db",  # Your Milvus connection URI
        "",  # Your Milvus token
    ),
    collection_name="camel_paper",
)

Importez et définissez l'instance du récupérateur :

Par défaut, l'adresse similarity_threshold est fixée à 0.75. Vous pouvez la modifier.

from camel.retrievers import VectorRetriever

vector_retriever = VectorRetriever(
    embedding_model=embedding_instance, storage=storage_instance
)

Nous utilisons Unstructured Module intégré pour diviser le contenu en petits morceaux, le contenu sera divisé automatiquement avec sa fonction chunk_by_title, le caractère maximum pour chaque morceau est de 500 caractères, ce qui est une longueur appropriée pour OpenAIEmbedding. Tout le texte contenu dans les morceaux sera intégré et stocké dans l'instance de stockage vectoriel, ce qui prendra un certain temps, veuillez patienter.

vector_retriever.process(content_input_path="local_data/camel paper.pdf")

[nltk_data] Downloading package punkt to /root/nltk_data...
[nltk_data]   Unzipping tokenizers/punkt.zip.

[nltk_data]     /root/nltk_data...
[nltk_data]   Unzipping taggers/averaged_perceptron_tagger.zip.

Nous pouvons maintenant extraire des informations du stockage vectoriel en lançant une requête. Par défaut, le système vous renverra le contenu textuel du premier bloc ayant le score de similarité cosinus le plus élevé, et le score de similarité doit être supérieur à 0,75 pour garantir que le contenu récupéré est pertinent par rapport à la requête. Vous pouvez également modifier la valeur de top_k.

La liste des chaînes renvoyées comprend

• score de similarité
• chemin d'accès au contenu
• métadonnées
• texte

retrieved_info = vector_retriever.query(query="What is CAMEL?", top_k=1)
print(retrieved_info)

[{'similarity score': '0.8321675658226013', 'content path': 'local_data/camel paper.pdf', 'metadata': {'last_modified': '2024-04-19T14:40:00', 'filetype': 'application/pdf', 'page_number': 45}, 'text': 'CAMEL Data and Code License The intended purpose and licensing of CAMEL is solely for research use. The source code is licensed under Apache 2.0. The datasets are licensed under CC BY NC 4.0, which permits only non-commercial usage. It is advised that any models trained using the dataset should not be utilized for anything other than research purposes.\n\n45'}]

Essayons une requête non pertinente :

retrieved_info_irrelevant = vector_retriever.query(
    query="Compared with dumpling and rice, which should I take for dinner?", top_k=1
)

print(retrieved_info_irrelevant)

[{'text': 'No suitable information retrieved from local_data/camel paper.pdf                 with similarity_threshold = 0.75.'}]

2. Auto RAG

Dans cette section, nous allons exécuter le programme AutoRetriever avec les paramètres par défaut. Il utilise OpenAIEmbedding comme modèle d'intégration par défaut et Milvus comme stockage vectoriel par défaut.

Voici ce que vous devez faire

• Définir les chemins d'entrée du contenu, qui peuvent être des chemins locaux ou des url distantes.
• Définir l'url distante et la clé api pour Milvus
• Donner une requête

Le pipeline Auto RAG créera des collections pour les chemins d'entrée de contenu donnés, le nom de la collection sera défini automatiquement en fonction du nom du chemin d'entrée de contenu, si la collection existe, elle sera récupérée directement.

from camel.retrievers import AutoRetriever
from camel.types import StorageType

auto_retriever = AutoRetriever(
    url_and_api_key=(
        "./milvus_demo.db",  # Your Milvus connection URI
        "",  # Your Milvus token
    ),
    storage_type=StorageType.MILVUS,
    embedding_model=embedding_instance,
)

retrieved_info = auto_retriever.run_vector_retriever(
    query="What is CAMEL-AI",
    content_input_paths=[
        "local_data/camel paper.pdf",  # example local path
        "https://www.camel-ai.org/",  # example remote url
    ],
    top_k=1,
    return_detailed_info=True,
)

print(retrieved_info)

3. Agent unique avec Auto RAG

Dans cette section, nous allons montrer comment combiner AutoRetriever avec un seul agent ChatAgent.

Mettons en place une fonction d'agent, dans cette fonction nous pouvons obtenir la réponse en fournissant une requête à cet agent.

from camel.agents import ChatAgent
from camel.messages import BaseMessage
from camel.types import RoleType
from camel.retrievers import AutoRetriever
from camel.types import StorageType


def single_agent(query: str) -> str:
    # Set agent role
    assistant_sys_msg = BaseMessage(
        role_name="Assistant",
        role_type=RoleType.ASSISTANT,
        meta_dict=None,
        content="""You are a helpful assistant to answer question,
         I will give you the Original Query and Retrieved Context,
        answer the Original Query based on the Retrieved Context,
        if you can't answer the question just say I don't know.""",
    )

    # Add auto retriever
    auto_retriever = AutoRetriever(
        url_and_api_key=(
            "./milvus_demo.db",  # Your Milvus connection URI
            "",  # Your Milvus token
        ),
        storage_type=StorageType.MILVUS,
        embedding_model=embedding_instance,
    )

    retrieved_info = auto_retriever.run_vector_retriever(
        query=query,
        content_input_paths=[
            "local_data/camel paper.pdf",  # example local path
            "https://www.camel-ai.org/",  # example remote url
        ],
        # vector_storage_local_path="storage_default_run",
        top_k=1,
        return_detailed_info=True,
    )

    # Pass the retrieved infomation to agent
    user_msg = BaseMessage.make_user_message(role_name="User", content=retrieved_info)
    agent = ChatAgent(assistant_sys_msg)

    # Get response
    assistant_response = agent.step(user_msg)
    return assistant_response.msg.content


print(single_agent("What is CAMEL-AI"))

CAMEL-AI is an open-source community dedicated to the study of autonomous and communicative agents. It provides, implements, and supports various types of agents, tasks, prompts, models, datasets, and simulated environments to facilitate research in this field.

{main termination reasons for AI Society dataset}
Retrieved Context:
Next we examine the conversation termination reasons for both AI Society and Code datasets. As can be seen in Figure 8, the main termination reasons for AI Society dataset is Assistant Instruct whereas for Code it is Token Limit. The latter is expected as the since responses that contain code tend to be long. It is also interesting to note that in both datasets, the termination due to Maximum Number of Messages is low indicating that the limit of 40 maximum messages is reasonable. Our decision t

Solution: The main termination reason for the AI Society dataset is "Assistant Instruct." This indicates that conversations in the AI Society dataset typically end when the assistant is instructed to terminate the conversation.
