Bug: segfault on clustering #529

Open vibl opened 2 weeks ago

vibl commented 2 weeks ago

Describe the bug

I get a segmentation fault on index.cluster(), whatever the parameters min_count and max_count I use (and without parameters).

Small dataset of 80,000 vectors. index.search works great.

Steps to reproduce


    index = Index(
        ndim=768,
        metric='cos',
        dtype='f32'
    )

    index.save(usearch_index_path)

    index = Index.restore(usearch_index_path)

    clustering = index.cluster(min_count=10, max_count=15, log=True)

Expected behavior

It should return a Clustering instance.

Hi @vibl! Sorry for delayed response! Can you check out the global clustering functionality as opposed to the built-in into the Index Python class? It should work much better.
