Is there a FOSS vectorizer to store things in the vectorDBs? I don't want to use the OpenAI embeddings API, looking for something that can be run entirely local.

Hi, I'm trying to get llama-index working with llamacpp to query documents entirely locally.
I have the code working for openai, but when I pass llamacpp as the LLMPredictor, my cpu just ramps to 100% and hangs for hours. Anyone have any idea how to proceed? M1 MBP 32G, normal llamacpp works great.
