Specifying endpoints/deployments for Azure OpenAI embeddings

[samuelp-mw]

Context

Currently, it is possible to use Azure both for chatbot and "chat with your data" use cases but this requires to adjust the environment variables locally to get it to work.

With the following set of environment variables (without OPENAI_API_KEY as we are using Azure-only), it is possible to perform a simple chat but the addition of data (in the assistant or in the chat itself) results in an error :

ANTHROPIC_API_KEY=placeholder
YDC_API_KEY=placeholder
TAVILY_API_KEY=placeholder
AZURE_OPENAI_DEPLOYMENT_NAME=placeholder
AZURE_OPENAI_API_KEY=placeholder
AZURE_OPENAI_API_BASE=placeholder
AZURE_OPENAI_API_VERSION=placeholder
CONNERY_RUNNER_URL=https://your-personal-connery-runner-url
CONNERY_RUNNER_API_KEY=placeholder
PROXY_URL=your_proxy_url
POSTGRES_PORT=placeholder
POSTGRES_DB=placeholder
POSTGRES_USER=placeholder
POSTGRES_PASSWORD=placeholder
SCARF_NO_ANALYTICS=true

The error occurs when ingesting data :

A similar problem is reported there (if I am not mistaken) :

• https://github.com/langchain-ai/opengpts/issues/286

Resolution

Unfortunately, AzureOpenAIEmbeddings expects AZURE_OPENAI_ENDPOINT to be set and we only have AZURE_OPENAI_BASE in the environment which causes the issues. Additionally, it might be useful to make the deployment name for embeddings configurable. Therefore the suggestion would be to read the needed variables and provide them as attributes to AzureOpenAIEmbeddings.
