incorrect reference for using GPU without index

[hongyuanmei]

in this tutorial page: https://github.com/facebookresearch/faiss/wiki/Brute-force-search-without-an-index there are a few incorrect references:

• it says "for numpy data, use contrib.exhaustive_search.knn_gpu, tested in gpu/test_contrib.py": that code doesn't have knn_gpu and knn_gpu is not in contrib.exhaustive_search; an example about knn_gpu is here https://github.com/facebookresearch/faiss/blob/main/faiss/gpu/test/torch_test_contrib_gpu.py
• it says "An example usage in python, from pytorch GPU data is here: test_pytorch_faiss.py", but there is no such page found.
