Original GitHub issue: https://github.com/open-webui/open-webui/issues/7956

I am in python 3.11 venv with the latest open-webui.

When using either llamacpp or ollama as the embedding backend, I get the following error. it doesn't matter what model or settings I use.

I can clearly see the GPUs start to get used and logs in llamacpp show its sending data, so it maybe its an incompatibility with the embedding model?
