DESCRIPTION:
This sample demonstrates how to get text embeddings for a list of sentences
using a synchronous client. Here we use the service default of returning
embeddings as a list of floating point values.
This sample assumes the AI model is hosted on a Serverless API or
Managed Compute endpoint. For GitHub Models or Azure OpenAI endpoints,
the client constructor needs to be modified. See package documentation:
https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/ai/azure-ai-inference/README.md#key-concepts
USAGE:
python sample_embeddings.py
Set these two environment variables before running the sample:
1) AZURE_AI_EMBEDDINGS_ENDPOINT - Your endpoint URL, in the form
https://<your-deployment-name>.<your-azure-region>.models.ai.azure.com
where `your-deployment-name` is your unique AI Model deployment name, and
`your-azure-region` is the Azure region where your model is deployed.
2) AZURE_AI_EMBEDDINGS_KEY - Your model key. Keep it secret.
