This dummy dataset is used for testing purpose for rag model in transformers. It is proudced via the following steps:
dataset = datasets.load_dataset("wiki_dpr", with_embeddings=True, with_index=True, index_name="exact", embeddings_name="nq", dummy=True, revision=None)
dataset["train"].drop_index("embeddings")
dataset.push_to_hub("hf-internal-testing/wiki_dpr_dummy", token="...")
The index file index.faiss (after being renamed locally) is then uploaded manually.
