We reviewed the paper and would like to test it out.
The installation instructions work fine and we are able to setup without too much effort. Great!

Running the default pdxearch_simple.py works with expected result.
One thing I noticed if i change the num_embeddings to a larger number like 300K or 1M, there will be seg fault at search time pointing to following stacktrace
#0 PDX::PDXearch<...>::EvaluatePruningPredicateOnPositionsArray
#1 PDX::PDXearch<...>::Prune
#2 PDX::PDXearch<...>::Search
#3 PDX::IndexADSamplingIVFFlat::_py_Search

Help would be appreciated. thanks
