Embedding with ollama

[kleyton67]

Env in Docker using ollama.
Trying to use embeddings from model: https://ollama.com/library/nomic-embed-text ;

Using example from https://langroid.github.io/langroid/tutorials/local-llm-setup/.

Changing
...
embed_provider: str = typer.Option(
"hf",
"--embed",
"-e",
help="Embedding service provider",
# openai, hf, llamacpp
),
embed_config: str = typer.Option(
"hf",
"--embedconfig",
"-ec",
help="Embedding service host/sentence transformer model",
),
...

        logger.info("Using embedding from ollama!!!")
        embed_cfg = lr.embedding_models.OpenAIEmbeddingsConfig(
            api_base="http://10.28.33.120:11434/v1",
            model_name=embed_config,
            api_key=" "
        )

...
agent = DocChatAgent(config)

When try to run the script, got the follow error:

ValueError:
OPENAI_API_KEY must be set in .env or your environment
to use OpenAIEmbeddings.

Behavior: The app end without finish process.

Expected behavior: Wait input for data to talk with docs.

OBS: My ollama api doesnt have api key (already using it with openwebUI).
