[Fabric] Leer y escribir storage con Databricks

Muchos lanzamientos y herramientas dentro de una sola plataforma haciendo participar tanto usuarios técnicos (data engineers, data scientists o data analysts) como usuarios finales. Fabric trajo una unión de involucrados en un único espacio. Ahora bien, eso no significa que tengamos que usar todas pero todas pero todas las herramientas que nos presenta.

Si ya disponemos de un excelente proceso de limpieza, transformación o procesamiento de datos con el gran popular Databricks, podemos seguir usándolo.

En posts anteriores hemos hablado que Fabric nos viene a traer un alamacenamiento de lake de última generación con open data format. Esto significa que nos permite utilizar los más populares archivos de datos para almacenar y que su sistema de archivos trabaja con las convencionales estructuras open source. En otras palabras podemos conectarnos a nuestro storage desde herramientas que puedan leerlo. También hemos mostrado un poco de Fabric notebooks y como nos facilita la experiencia de desarrollo.

En este sencillo tip vamos a ver como leer y escribir, desde databricks, nuestro Fabric Lakehouse.

Para poder comunicarnos entre databricks y Fabric lo primero es crear un recurso AzureDatabricks Premium Tier. Lo segundo, asegurarnos de dos cosas en nuestro cluster:

Utilizar un policy "unrestricted" o "power user compute"

2. Asegurarse que databricks podría pasar nuestras credenciales por spark. Eso podemos activarlo en las opciones avanzadas

NOTA: No voy a entrar en más detalles de creación de cluster. El resto de las opciones de procesamiento les dejo que investiguen o estimo que ya conocen si están leyendo este post.

Ya creado nuestro cluster vamos a crear un notebook y comenzar a leer data en Fabric. Esto lo vamos a conseguir con el ABFS (Azure Bllob Fyle System) que es una dirección de formato abierto cuyo driver está incluido en Azure Databricks.

La dirección debe componerse de algo similar a la siguiente cadena:

oneLakePath = 'abfss://myWorkspaceId@onelake.dfs.fabric.microsoft.com/myLakehouse.lakehouse/Files/'

Conociendo dicha dirección ya podemos comenzar a trabajar como siempre. Veamos un simple notebook que para leer un archivo parquet en Lakehouse Fabric

Gracias a la configuración del cluster, los procesos son tan simples como spark.read

Así de simple también será escribir.

Iniciando con una limpieza de columnas innecesarias y con un sencillo [frame].write ya tendremos la tabla en silver limpia.

Nos vamos a Fabric y podremos encontrarla en nuestro Lakehouse

Así concluye nuestro procesamiento de databricks en lakehouse de Fabric, pero no el artículo. Todavía no hablamos sobre el otro tipo de almacenamiento en el blog pero vamos a mencionar lo que pertine a ésta lectura.

Los Warehouses en Fabric también están constituidos con una estructura tradicional de lake de última generación. Su principal diferencia consiste en brindar una experiencia de usuario 100% basada en SQL como si estuvieramos trabajando en una base de datos. Sin embargo, por detras, podrémos encontrar delta como un spark catalog o metastore.

El path debería verse similar a esto:

path_dw = "abfss://WorkspaceName@onelake.dfs.fabric.microsoft.com/WarehouseName.Datawarehouse/Tables/dbo/"

Teniendo en cuenta que Fabric busca tener contenido delta en su Spark Catalog de Lakehouse (tables) y en su Warehouse, vamos a leer como muestra el siguiente ejemplo

Ahora si concluye nuestro artículo mostrando como podemos utilizar Databricks para trabajar con los almacenamientos de Fabric.

Tracking Large Language Models (LLM) with MLflow : A Complete Guide

New Post has been published on https://thedigitalinsider.com/tracking-large-language-models-llm-with-mlflow-a-complete-guide/

Tracking Large Language Models (LLM) with MLflow : A Complete Guide

As Large Language Models (LLMs) grow in complexity and scale, tracking their performance, experiments, and deployments becomes increasingly challenging. This is where MLflow comes in – providing a comprehensive platform for managing the entire lifecycle of machine learning models, including LLMs.

In this in-depth guide, we’ll explore how to leverage MLflow for tracking, evaluating, and deploying LLMs. We’ll cover everything from setting up your environment to advanced evaluation techniques, with plenty of code examples and best practices along the way.

Functionality of MLflow in Large Language Models (LLMs)

MLflow has become a pivotal tool in the machine learning and data science community, especially for managing the lifecycle of machine learning models. When it comes to Large Language Models (LLMs), MLflow offers a robust suite of tools that significantly streamline the process of developing, tracking, evaluating, and deploying these models. Here’s an overview of how MLflow functions within the LLM space and the benefits it provides to engineers and data scientists.

Tracking and Managing LLM Interactions

MLflow’s LLM tracking system is an enhancement of its existing tracking capabilities, tailored to the unique needs of LLMs. It allows for comprehensive tracking of model interactions, including the following key aspects:

Parameters: Logging key-value pairs that detail the input parameters for the LLM, such as model-specific parameters like top_k and temperature. This provides context and configuration for each run, ensuring that all aspects of the model’s configuration are captured.

Metrics: Quantitative measures that provide insights into the performance and accuracy of the LLM. These can be updated dynamically as the run progresses, offering real-time or post-process insights.

Predictions: Capturing the inputs sent to the LLM and the corresponding outputs, which are stored as artifacts in a structured format for easy retrieval and analysis.

Artifacts: Beyond predictions, MLflow can store various output files such as visualizations, serialized models, and structured data files, allowing for detailed documentation and analysis of the model’s performance.

This structured approach ensures that all interactions with the LLM are meticulously recorded, providing a comprehensive lineage and quality tracking for text-generating models​.

Evaluation of LLMs

Evaluating LLMs presents unique challenges due to their generative nature and the lack of a single ground truth. MLflow simplifies this with specialized evaluation tools designed for LLMs. Key features include:

Versatile Model Evaluation: Supports evaluating various types of LLMs, whether it’s an MLflow pyfunc model, a URI pointing to a registered MLflow model, or any Python callable representing your model.

Comprehensive Metrics: Offers a range of metrics tailored for LLM evaluation, including both SaaS model-dependent metrics (e.g., answer relevance) and function-based metrics (e.g., ROUGE, Flesch Kincaid).

Predefined Metric Collections: Depending on the use case, such as question-answering or text-summarization, MLflow provides predefined metrics to simplify the evaluation process.

Custom Metric Creation: Allows users to define and implement custom metrics to suit specific evaluation needs, enhancing the flexibility and depth of model evaluation.

Evaluation with Static Datasets: Enables evaluation of static datasets without specifying a model, which is useful for quick assessments without rerunning model inference.

Deployment and Integration

MLflow also supports seamless deployment and integration of LLMs:

MLflow Deployments Server: Acts as a unified interface for interacting with multiple LLM providers. It simplifies integrations, manages credentials securely, and offers a consistent API experience. This server supports a range of foundational models from popular SaaS vendors as well as self-hosted models.

Unified Endpoint: Facilitates easy switching between providers without code changes, minimizing downtime and enhancing flexibility.

Integrated Results View: Provides comprehensive evaluation results, which can be accessed directly in the code or through the MLflow UI for detailed analysis.

MLflow is a comprehensive suite of tools and integrations makes it an invaluable asset for engineers and data scientists working with advanced NLP models.

Setting Up Your Environment

Before we dive into tracking LLMs with MLflow, let’s set up our development environment. We’ll need to install MLflow and several other key libraries:

pip install mlflow>=2.8.1 pip install openai pip install chromadb==0.4.15 pip install langchain==0.0.348 pip install tiktoken pip install 'mlflow[genai]' pip install databricks-sdk --upgrade

After installation, it’s a good practice to restart your Python environment to ensure all libraries are properly loaded. In a Jupyter notebook, you can use:

import mlflow import chromadb print(f"MLflow version: mlflow.__version__") print(f"ChromaDB version: chromadb.__version__")

This will confirm the versions of key libraries we’ll be using.

Understanding MLflow’s LLM Tracking Capabilities

MLflow’s LLM tracking system builds upon its existing tracking capabilities, adding features specifically designed for the unique aspects of LLMs. Let’s break down the key components:

Runs and Experiments

In MLflow, a “run” represents a single execution of your model code, while an “experiment” is a collection of related runs. For LLMs, a run might represent a single query or a batch of prompts processed by the model.

Key Tracking Components

Parameters: These are input configurations for your LLM, such as temperature, top_k, or max_tokens. You can log these using mlflow.log_param() or mlflow.log_params().

Metrics: Quantitative measures of your LLM’s performance, like accuracy, latency, or custom scores. Use mlflow.log_metric() or mlflow.log_metrics() to track these.

Predictions: For LLMs, it’s crucial to log both the input prompts and the model’s outputs. MLflow stores these as artifacts in CSV format using mlflow.log_table().

Artifacts: Any additional files or data related to your LLM run, such as model checkpoints, visualizations, or dataset samples. Use mlflow.log_artifact() to store these.

Let’s look at a basic example of logging an LLM run:

This example demonstrates logging parameters, metrics, and the input/output as a table artifact.

import mlflow import openai def query_llm(prompt, max_tokens=100): response = openai.Completion.create( engine="text-davinci-002", prompt=prompt, max_tokens=max_tokens ) return response.choices[0].text.strip() with mlflow.start_run(): prompt = "Explain the concept of machine learning in simple terms." # Log parameters mlflow.log_param("model", "text-davinci-002") mlflow.log_param("max_tokens", 100) # Query the LLM and log the result result = query_llm(prompt) mlflow.log_metric("response_length", len(result)) # Log the prompt and response mlflow.log_table("prompt_responses", "prompt": [prompt], "response": [result]) print(f"Response: result")

Deploying LLMs with MLflow

MLflow provides powerful capabilities for deploying LLMs, making it easier to serve your models in production environments. Let’s explore how to deploy an LLM using MLflow’s deployment features.

Creating an Endpoint

First, we’ll create an endpoint for our LLM using MLflow’s deployment client:

import mlflow from mlflow.deployments import get_deploy_client # Initialize the deployment client client = get_deploy_client("databricks") # Define the endpoint configuration endpoint_name = "llm-endpoint" endpoint_config = "served_entities": [ "name": "gpt-model", "external_model": "name": "gpt-3.5-turbo", "provider": "openai", "task": "llm/v1/completions", "openai_config": "openai_api_type": "azure", "openai_api_key": "secrets/scope/openai_api_key", "openai_api_base": "secrets/scope/openai_api_base", "openai_deployment_name": "gpt-35-turbo", "openai_api_version": "2023-05-15", , , ], # Create the endpoint client.create_endpoint(name=endpoint_name, config=endpoint_config)

This code sets up an endpoint for a GPT-3.5-turbo model using Azure OpenAI. Note the use of Databricks secrets for secure API key management.

Testing the Endpoint

Once the endpoint is created, we can test it:

<div class="relative flex flex-col rounded-lg"> response = client.predict( endpoint=endpoint_name, inputs="prompt": "Explain the concept of neural networks briefly.","max_tokens": 100,,) print(response)

This will send a prompt to our deployed model and return the generated response.

Evaluating LLMs with MLflow

Evaluation is crucial for understanding the performance and behavior of your LLMs. MLflow provides comprehensive tools for evaluating LLMs, including both built-in and custom metrics.

Preparing Your LLM for Evaluation

To evaluate your LLM with mlflow.evaluate(), your model needs to be in one of these forms:

An mlflow.pyfunc.PyFuncModel instance or a URI pointing to a logged MLflow model.

A Python function that takes string inputs and outputs a single string.

An MLflow Deployments endpoint URI.

Set model=None and include model outputs in the evaluation data.

Let’s look at an example using a logged MLflow model:

import mlflow import openai with mlflow.start_run(): system_prompt = "Answer the following question concisely." logged_model_info = mlflow.openai.log_model( model="gpt-3.5-turbo", task=openai.chat.completions, artifact_path="model", messages=[ "role": "system", "content": system_prompt, "role": "user", "content": "question", ], ) # Prepare evaluation data eval_data = pd.DataFrame( "question": ["What is machine learning?", "Explain neural networks."], "ground_truth": [ "Machine learning is a subset of AI that enables systems to learn and improve from experience without explicit programming.", "Neural networks are computing systems inspired by biological neural networks, consisting of interconnected nodes that process and transmit information." ] ) # Evaluate the model results = mlflow.evaluate( logged_model_info.model_uri, eval_data, targets="ground_truth", model_type="question-answering", ) print(f"Evaluation metrics: results.metrics")

This example logs an OpenAI model, prepares evaluation data, and then evaluates the model using MLflow’s built-in metrics for question-answering tasks.

Custom Evaluation Metrics

MLflow allows you to define custom metrics for LLM evaluation. Here’s an example of creating a custom metric for evaluating the professionalism of responses:

from mlflow.metrics.genai import EvaluationExample, make_genai_metric professionalism = make_genai_metric( name="professionalism", definition="Measure of formal and appropriate communication style.", grading_prompt=( "Score the professionalism of the answer on a scale of 0-4:n" "0: Extremely casual or inappropriaten" "1: Casual but respectfuln" "2: Moderately formaln" "3: Professional and appropriaten" "4: Highly formal and expertly crafted" ), examples=[ EvaluationExample( input="What is MLflow?", output="MLflow is like your friendly neighborhood toolkit for managing ML projects. It's super cool!", score=1, justification="The response is casual and uses informal language." ), EvaluationExample( input="What is MLflow?", output="MLflow is an open-source platform for the machine learning lifecycle, including experimentation, reproducibility, and deployment.", score=4, justification="The response is formal, concise, and professionally worded." ) ], model="openai:/gpt-3.5-turbo-16k", parameters="temperature": 0.0, aggregations=["mean", "variance"], greater_is_better=True, ) # Use the custom metric in evaluation results = mlflow.evaluate( logged_model_info.model_uri, eval_data, targets="ground_truth", model_type="question-answering", extra_metrics=[professionalism] ) print(f"Professionalism score: results.metrics['professionalism_mean']")

This custom metric uses GPT-3.5-turbo to score the professionalism of responses, demonstrating how you can leverage LLMs themselves for evaluation.

Advanced LLM Evaluation Techniques

As LLMs become more sophisticated, so do the techniques for evaluating them. Let’s explore some advanced evaluation methods using MLflow.

Retrieval-Augmented Generation (RAG) Evaluation

RAG systems combine the power of retrieval-based and generative models. Evaluating RAG systems requires assessing both the retrieval and generation components. Here’s how you can set up a RAG system and evaluate it using MLflow:

from langchain.document_loaders import WebBaseLoader from langchain.text_splitter import CharacterTextSplitter from langchain.embeddings import OpenAIEmbeddings from langchain.vectorstores import Chroma from langchain.chains import RetrievalQA from langchain.llms import OpenAI # Load and preprocess documents loader = WebBaseLoader(["https://mlflow.org/docs/latest/index.html"]) documents = loader.load() text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0) texts = text_splitter.split_documents(documents) # Create vector store embeddings = OpenAIEmbeddings() vectorstore = Chroma.from_documents(texts, embeddings) # Create RAG chain llm = OpenAI(temperature=0) qa_chain = RetrievalQA.from_chain_type( llm=llm, chain_type="stuff", retriever=vectorstore.as_retriever(), return_source_documents=True ) # Evaluation function def evaluate_rag(question): result = qa_chain("query": question) return result["result"], [doc.page_content for doc in result["source_documents"]] # Prepare evaluation data eval_questions = [ "What is MLflow?", "How does MLflow handle experiment tracking?", "What are the main components of MLflow?" ] # Evaluate using MLflow with mlflow.start_run(): for question in eval_questions: answer, sources = evaluate_rag(question) mlflow.log_param(f"question", question) mlflow.log_metric("num_sources", len(sources)) mlflow.log_text(answer, f"answer_question.txt") for i, source in enumerate(sources): mlflow.log_text(source, f"source_question_i.txt") # Log custom metrics mlflow.log_metric("avg_sources_per_question", sum(len(evaluate_rag(q)[1]) for q in eval_questions) / len(eval_questions))

This example sets up a RAG system using LangChain and Chroma, then evaluates it by logging questions, answers, retrieved sources, and custom metrics to MLflow.

The way you chunk your documents can significantly impact RAG performance. MLflow can help you evaluate different chunking strategies:

This script evaluates different combinations of chunk sizes, overlaps, and splitting methods, logging the results to MLflow for easy comparison.

MLflow provides various ways to visualize your LLM evaluation results. Here are some techniques:

You can create custom visualizations of your evaluation results using libraries like Matplotlib or Plotly, then log them as artifacts:

This function creates a line plot comparing a specific metric across multiple runs and logs it as an artifact.
