DESCRIPTION:
This sample demonstrates how to use agent operations with interation in streaming from
the Azure Agents service using a asynchronous client.
USAGE:
python sample_agents_stream_iteration_async.py
Before running the sample:
pip install azure-ai-agents azure-identity aiohttp
Set these environment variables with your own values:
1) PROJECT_ENDPOINT - The Azure AI Project endpoint, as found in the Overview
page of your Azure AI Foundry portal.
2) MODEL_DEPLOYMENT_NAME - The deployment name of the AI model.
