how to evaluate RAG-end2end

Hi,

Is there a script like eval_rag.py but for RAG-end2end ? I see that the eval_rag.py file in the RAG-end2end folder is the same as for RAG, but I am not sure on how to adapt it to load the finetuned dpr_ctx_encoder from a RAG-end2end checkpoint, which seems not that trivial.

Thank you
