You possibly can construct the RAG utility utilizing any framework, together with native Python code, however on this instance, we’re utilizing Langchain.
# ##################################
# Hook up 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 appliance. This may be finished by including three easy traces within the utility code (above) that enable Agent Framework to supply traces and a straightforward approach to observe and debug the appliance.
## Allow MLflow Tracing
mlflow.langchain.autolog()
## Inform MLflow concerning the schema of the retriever in order that
# 1. Assessment 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'), # Assessment 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 supplies observability into your utility throughout growth and manufacturing
The following 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 Assessment App any person in your SSO
brokers.set_permissions(model_name=UC_MODEL_NAME,
customers=["[email protected]"],
permission_level=brokers.PermissionLevel.CAN_QUERY)You possibly can 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.
