⚠️ WARNING: This repository is deprecated and no longer maintained ⚠️

There is a new repository that covers the latest Azure AI code-first experiences. Navigate to and star this one instead: https://github.com/Azure-Samples/rag-data-openai-python-promptflow/tree/main

❗Important

Features used in this repository are in preview. Preview versions are provided without a service level agreement, and they are not recommended for production workloads. Certain features might not be supported or might have constrained capabilities. For more information, see Supplemental Terms of Use for Microsoft Azure Previews.

Getting Started

This repository contains a copilot getting started sample that can be used with the the Azure AI Studio preview.

The sample walks through creating a copilot enterprise chat API that uses custom Python code to ground the copilot responses in your company data and APIs. The sample is meant to provide a starting point that you can further customize to add additional intelligence or capabilities. Following the below steps in the README, you will be able to: set up your development environment, create your Azure AI resources and project, build an index containing product information, run your co-pilot, evaluate it, and deploy & invoke an API.

NOTE: We do not guarantee the quality of responses produced by this sample copilot or its suitability for use in your scenario, and responses will vary as development of this sample is ongoing. You must perform your own validation the outputs of the copilot and its suitability for use within your company.

Step 1: Set up your development environment

Step 1a: Use a cloud development environment

Explore sample with Codespaces

• To get started quickly with this sample, you can use a pre-built Codespaces development environment. Click the button below to open this repo in GitHub Codespaces, and then continue the readme!

• Once you've launched Codespaces you can proceed to step 2.

Start developing in an Azure AI curated VS Code development environment

• If you intend to develop your own code following this sample, we recommend you use the Azure AI curated VS Code development environment. It comes preconfigured with the Azure AI SDK packages that you will use to run this sample.
• You can get started with this cloud environment from the Azure AI Studio by following these steps: Work with Azure AI projects in VS Code

❕ Important: If you are viewing this README from within this cloud VS Code environment, you can proceed directly to step 2! This case will apply to you if you launched VS Code from an Azure AI Studio project. The AI SDK packages are already installed.

Step 1b: Alternatively, set up your local development environment

1. First, clone the code sample locally:

git clone https://github.com/azure/aistudio-copilot-sample
cd aistudio-copilot-sample

2. Next, create a new Python virtual environment where we can safely install the SDK packages:

• On MacOS and Linux run:

  python3 --version
  python3 -m venv .venv
  

  source .venv/bin/activate
  

• On Windows run:

  py -3 --version
  py -3 -m venv .venv
  

  .venv\scripts\activate
  

3. Now that your environment is activated, install the SDK packages

pip install -r requirements.txt

Step 2: Set your Azure resource environment variables

Note: You'll need to deploy a chat completions model (e.g. GPT-4) and a text embedding model (e.g. text-embedding-ada-002) to run the sample. Do this in the Azure AI Model Catalog.

Create a .env file to store your Azure keys and endpoints. Copy the contents of the example .env file (.env.sample) into your .env file. This is where you will reference environment variables in the code.

To find your keys, deployments, and connections, open your project in AI Studio. Navigate to the Settings page and copy over the following values:

• Azure subscription ID
• Azure OpenAI API key, endpoint, and API version
• Azure AI Search key, endpoint, and index name (change the AI Search Index project name to be lowercase)
• Azure OpenAI chat model, deployment, evaluation model (these can be the same, e.g. gpt4)
• Azure OpenAI evaluation model (the text name of the model, e.g. "gpt4")
• Azure OpenAI Embedding model and embedding deployment (these should be the same, e.g. text-embedding-ada-002)

Note: You can open your project in AI Studio to view your projects configuration and components (generated indexes, evaluation runs, and endpoints). You can also create new resources, deployments and connections here to use in your code.

Step 3: Build an Azure AI Search index

Context

You'll create a search index to retrieve our product data through code. When we run our Python program (run.py), the argument --build-index creates an Azure Search index via the SDK.

This sample uses a set of markdown files with product information for the fictitious Contoso Trek retailer stored in data/3-product-info folder. If you want to follow this sample directly, follow the steps below. You can also run the build_cogsearch_index command using a different folder of data, or replace the contents of the folder with your own documents.

Run the commands

In the run.py file, find where the method build_cogsearch_index is invoked, and specify your index name and dataset path. The method invocation should look like this:

build_cogsearch_index("product-info", "./data/3-product-info")

Then, run the following command in the command line to create the search index:

python src/run.py --build-index

Step 4: Run the copilot with a sample question

To run a single question & answer through the sample co-pilot:

python src/run.py --question "which tent is the most waterproof?"

Note: you may see a warning about a RuntimeError; it can be safely ignored - evaluation will be unaffected. We are working to resolve this output issue.

You can try out different sample implementations by specifying the --implementation flag with promptflow, langchain or aisdk.

❕ If you try out the promptflow implementation, first check that your deployment names (both embedding and chat) and index name (if it's changed from the previous steps) in src/copilot_promptflow/flow.dag.yaml match what's in the .env file.

python src/run.py --question "which tent is the most waterproof?" --implementation promptflow

Step 5: Test the copilots using a chat completion model to evaluate results

To run evaluation on a copilot implementations:

python src/run.py --evaluate --implementation aisdk

You can change aisdk to any of the other implementation names to run an evaluation on them.

Step 6: Deploy the sample code

To deploy one of the implementations to an online endpoint, use:

python src/run.py --deploy

To test out the online enpoint, run:

python src/run.py --invoke 

Additional Tips and Resources

Customize the development container

You can pip install packages into your development environment but they will disappear if you rebuild your container and need to be reinstalled (re-build is not automatic). You may want this, so that you can easily reset back to a clean environment. Or, you may want to install some packages by default into the container so that you don't need to re-install packages after a rebuild.

To add packages into the default container, you can update the Dockerfile in .devcontainer/Dockerfile, and then rebuild the development container from the command palette by pressing Ctrl/Cmd+Shift+P and selecting the Rebuild container command.
