Constructing a high-quality RAG agent
To grasp these new capabilities, let’s stroll via an instance of constructing a high-quality agentic utility utilizing Agent Framework and enhancing its high quality utilizing Agent Analysis. You’ll be able to have a look at the whole code for this instance and extra superior examples within the Generative AI Cookbook right here.
On this instance, we’re going to construct and deploy a easy RAG utility that retrieves related chunks from a pre-created vector index and summarizes them as a response to a question. You’ll be able to construct the RAG utility utilizing any framework, together with native Python code, however on this instance, we’re utilizing Langchain.
# ##################################
# Connect with the Vector Search Index
# ##################################
vs_client = VectorSearchClient()
vs_index = vs_client.get_index(
endpoint_name="vector_search_endpoint",
index_name="vector_index_name",
)
# ##################################
# Set the Vector Search index right into a LangChain retriever
# ##################################
vector_search_as_retriever = DatabricksVectorSearch(
vs_index,
text_column='chunk_text',
columns=['chunk_id', 'chunk_text', 'document_uri'],
).as_retriever()
# ##################################
# RAG Chain
# ##################################
immediate = PromptTemplate(
template = "Reply the query...",
input_variables = ["question", "context"],
)
chain = (
vector_search_as_retriever,
| immediate
| ChatDatabricks(endpoint='dbrx_endpoint')
| StrOutputParser()
)The very first thing we wish to do is leverage MLflow to allow traces and deploy the applying. This may be completed by including three easy traces within the utility code (above) that permit Agent Framework to offer traces and a simple method to observe and debug the applying.
## Allow MLflow Tracing
mlflow.langchain.autolog()
## Inform MLflow in regards to the schema of the retriever in order that
# 1. Evaluate App can correctly show retrieved chunks
# 2. Agent Analysis can measure the retriever
############
mlflow.fashions.set_retriever_schema(
primary_key='chunk_id'),
text_column='chunk_text',
doc_uri='document_uri'), # Evaluate App makes use of `doc_uri` to show
chunks from the identical doc in a single view
)
## Inform MLflow logging the place to search out your chain.
mlflow.fashions.set_model(mannequin=chain)
MLflow Tracing gives observability into your utility throughout improvement and manufacturing
The subsequent step is to register the GenAI utility in Unity Catalog and deploy it as a proof of idea to get suggestions from stakeholders utilizing Agent Analysis’s evaluation utility.
# Use Unity Catalog to log the chain
mlflow.set_registry_uri('databricks-uc')
UC_MODEL_NAME='databricks-rag-app'
# Register the chain to UC
uc_registered_model_info = mlflow.register_model(model_uri=model_uri,
title=UC_MODEL_NAME)
# Use Agent Framework to deploy a mannequin registed in UC to the Agent
Analysis evaluation utility & create an agent serving endpoint
deployment_info = brokers.deploy(model_name=UC_MODEL_NAME,
model_version=uc_model.model)
# Assign permissions to the Evaluate App any person in your SSO
brokers.set_permissions(model_name=UC_MODEL_NAME,
customers=["[email protected]"],
permission_level=brokers.PermissionLevel.CAN_QUERY)You’ll be able to share the browser hyperlink with stakeholders and begin getting suggestions instantly! The suggestions is saved as delta tables in your Unity Catalog and can be utilized to construct an analysis dataset.
