chroma vector store creator error (linux)

Hi,
I am tring to get the chroma vector store creator node to run using the GPT4all embedding connector, however i am getting the error:
Execute failed: The onnxruntime python package is not installed. Please install it with pip install onnxruntime

In preferences I am pointing python at one conda environment which I have checked has both onnxruntime and chromadb within it.

Howerver for the Chroma Vector Store node does this use a different environment ? perhaps the deep learning one?

Thanks
