[D]: Best nearest neighbour search for high dimensions
I'll assume this is the link to pynndescent, looks cool! Thanks for sharing. I haven't used it before. Also seems like it's an approximate nearest neighbor algorithm, just FYI for others seeing this.

How to find "k" nearest embeddings in a space with a very large number of N embeddings (efficiently)?
If you just want quick in memory search then pynndescent is a decent option: it's easy to install, and easy to get running. Another good option is Annoy; it's just as easy to install and get running with python, but it is a little less performant if you want to do a lot of queries, or get a knn-graph quickly.

PynnDescent: Importing pickled index gives error - 'NNDescent' object has no attribute 'shape'
Using the latest version of PyNNDescent via pip install. Running this on Google Colab with python 3.7.13Followed the Docs and created an index with the paramspynnindex = pynndescent.NNDescent(arr, metric="cosine", n_neighbors=100)Everything works fine and I get results from pynnindex.neighbor_graph as expected.
