Regarding Rag-end2end retriever

How to use the finetuned rag-end2end retriever for model prediction similar to hugging face.
for eg: model.generate(“text”) and answer should be there
trainer.test() in ( what is this supposed to do exactly?)

Hi, for that you need to finetune your models and use the checkpoints. But it is not simple as other language models, since RAG has a retrieval phase. Please follow the HF documentation of RAG.
