+The model can be loaded and used as follows on [this branch](https://github.com/huggingface/transformers/tree/finalize_rag) as follows.
+
+
+# Load model
+
+```python
+from transformers import RagTokenizer, RagTokenForGeneration, RagRetriever
+
+# create Retriever augmented model
+retriever = RagRetriever.from_pretrained("facebook/rag-token-nq_new", use_dummy_dataset=True)
+model = RagTokenForGeneration.from_pretrained("facebook/rag-token-nq_new", retriever=retriever)
+
+tokenizer = RagTokenizer.from_pretrained("facebook/rag-token-nq_new")
+
+# create input ids and labels
+input_ids = tokenizer("who sings does he love me with reba", return_tensors="pt").input_ids
+
+# use labels
+labels = tokenizer.generator("Linda Davis", return_tensors="pt").input_ids
+
+
+# compute loss
+outputs = model(input_ids, labels=labels)
+```
