azure-ai-evaluation 1.0.0b3

Microsoft Azure Evaluation Library for Python

Azure AI Evaluation client library for Python

We are excited to introduce the public preview of the Azure AI Evaluation SDK.

Source code | Package (PyPI) | API reference documentation | Product documentation | Samples

This package has been tested with Python 3.8, 3.9, 3.10, 3.11, and 3.12.

For a more complete set of Azure libraries, see https://aka.ms/azsdk/python/all

Getting started

Prerequisites

• Python 3.8 or later is required to use this package.

Install the package

Install the Azure AI Evaluation library for Python with pip::

pip install azure-ai-evaluation

Key concepts

Evaluators are custom or prebuilt classes or functions that are designed to measure the quality of the outputs from language models.

Examples

Evaluators

Users can create evaluator runs on the local machine as shown in the example below:

import os
from pprint import pprint

from azure.ai.evaluation import evaluate, RelevanceEvaluator, ViolenceEvaluator


def response_length(response, **kwargs):
    return {"value": len(response)}


if __name__ == "__main__":
    # Built-in evaluators
    # Initialize Azure OpenAI Model Configuration
    model_config = {
        "azure_endpoint": os.environ.get("AZURE_OPENAI_ENDPOINT"),
        "api_key": os.environ.get("AZURE_OPENAI_KEY"),
        "azure_deployment": os.environ.get("AZURE_OPENAI_DEPLOYMENT"),
    }

    # Initialzing Relevance Evaluator
    relevance_eval = RelevanceEvaluator(model_config)

    # Running Relevance Evaluator on single input row
    relevance_score = relevance_eval(
        response="The Alpine Explorer Tent is the most waterproof.",
        context="From the our product list,"
        " the alpine explorer tent is the most waterproof."
        " The Adventure Dining Table has higher weight.",
        query="Which tent is the most waterproof?",
    )

    pprint(relevance_score)
    # {'gpt_relevance': 5.0}

    # Content Safety Evaluator

    # Initialize Project Scope
    azure_ai_project = {
        "subscription_id": <subscription_id>,
        "resource_group_name": <resource_group_name>,
        "project_name": <project_name>
    }

    violence_eval = ViolenceEvaluator(azure_ai_project)
    violence_score = violence_eval(query="What is the capital of France?", response="Paris.")
    pprint(violence_score)
    # {'violence': 'Very low',
    # 'violence_reason': "The system's response is a straightforward factual response "
    #                    'to a geography question. There is no violent content or '
    #                    'language present.',
    # 'violence_score': 0}

    # Code based evaluator
    response_length("The Alpine Explorer Tent is the most waterproof.")
    # {'value': 48}

    # Using multiple evaluators together using `Evaluate` API

    result = evaluate(
        data="evaluate_test_data.jsonl",
        evaluators={
            "response_length": response_length,
            "violence": violence_eval,
        },
    )

    pprint(result)

Simulator

Simulators allow users to generate synthentic data using their application. Simulator expects the user to have a callback method that invokes their AI application.

Simulating with a Prompty

Troubleshooting

General

Azure ML clients raise exceptions defined in Azure Core.

Logging

This library uses the standard logging library for logging. Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO level.

Detailed DEBUG level logging, including request/response bodies and unredacted headers, can be enabled on a client with the logging_enable argument.

See full SDK logging documentation with examples here.

Release History

1.0.0b3 (2024-10-01)

Features Added

• Added type field to AzureOpenAIModelConfiguration and OpenAIModelConfiguration
• The following evaluators now support conversation as an alternative input to their usual single-turn inputs:
  • ViolenceEvaluator
  • SexualEvaluator
  • SelfHarmEvaluator
  • HateUnfairnessEvaluator
  • ProtectedMaterialEvaluator
  • IndirectAttackEvaluator
  • CoherenceEvaluator
  • RelevanceEvaluator
  • FluencyEvaluator
  • GroundednessEvaluator
• Surfaced RetrievalScoreEvaluator, formally an internal part of ChatEvaluator as a standalone conversation-only evaluator.

Breaking Changes

• Removed ContentSafetyChatEvaluator and ChatEvaluator
• The evaluator_config parameter of evaluate now maps in evaluator name to a dictionary EvaluatorConfig, which is a TypedDict. The column_mapping between data or target and evaluator field names should now be specified inside this new dictionary:

Before:

evaluate(
    ...,
    evaluator_config={
        "hate_unfairness": {
            "query": "${data.question}",
            "response": "${data.answer}",
        }
    },
    ...
)

After

evaluate(
    ...,
    evaluator_config={
        "hate_unfairness": {
            "column_mapping": {
                "query": "${data.question}",
                "response": "${data.answer}",
             }
        }
    },
    ...
)

Bugs Fixed

• Fixed issue where Entra ID authentication was not working with AzureOpenAIModelConfiguration

1.0.0b2 (2024-09-24)

Breaking Changes

• data and evaluators are now required keywords in evaluate.

1.0.0b1 (2024-09-20)

Breaking Changes

• The synthetic namespace has been renamed to simulator, and sub-namespaces under this module have been removed
• The evaluate and evaluators namespaces have been removed, and everything previously exposed in those modules has been added to the root namespace azure.ai.evaluation
• The parameter name project_scope in content safety evaluators have been renamed to azure_ai_project for consistency with evaluate API and simulators.
• Model configurations classes are now of type TypedDict and are exposed in the azure.ai.evaluation module instead of coming from promptflow.core.
• Updated the parameter names for question and answer in built-in evaluators to more generic terms: query and response.

Features Added

• First preview
• This package is port of promptflow-evals. New features will be added only to this package moving forward.
• Added a TypedDict for AzureAIProject that allows for better intellisense and type checking when passing in project information
