 To use the modified splits as described in the [paper](https://arxiv.org/abs/2104.07567), set the following flags for the seen/unseen splits, respectively:
 
-    parlai dd -t cmu_dog --cmu-dog-split-type seen

 #### Train a BlenderBot-2.7B RAG Sequence Model with DPR-Poly Retrieval on WoW
 
 For the BlenderBot model, we add extra positions to the encoder, so that we can retain additional information from the retrieved documents.
