Implementation from cuML in Berttopic

@MaartenGr As `cuml.cluster.HDBSCAN` is not an instance of `hdbscan.HDBSCAN`, the isinstance checks in lines 388, 1431 and 1548 return False, resulting in the probabilities (`hdbscan_model.probabilities_`) being ignored, although the cuml...

Add a GROUP BY operator

I find this functionality missing in my workflow as well and the workarounds with SQL and Polars unsatisfying. Since PyArrow has exposed this functionality, I hope this soon makes it...

[QST] Dispatch model to specific GPU

Thanks. That would be fairly complicated, though - is there no demand for this functionality? It seems like it shouldn't be difficult to implement, no?

[FEA] Reduce memory pressure in HDBSCAN all_points_membership_vectors (or provide/link to best practices)

I've switched to 23.04 and tried using HDBSCAN with batch_size set to various values, but I still quickly run out of memory. Before I investigate this further, I was wondering...

[FEA] Reduce memory pressure in HDBSCAN all_points_membership_vectors (or provide/link to best practices)

Hi, I'm looking into this now, but I can't seem to find that gpu_memory_profiler extension you're using for measuring gpu memory usage - can someone point me to it? @beckernick

[FEA] Reduce memory pressure in HDBSCAN all_points_membership_vectors (or provide/link to best practices)

I was getting some weird results when using the python nvml bindings and when I was running things in a separate process (to avoid the kernel crashing when I run...

[FEA] Reduce memory pressure in HDBSCAN all_points_membership_vectors (or provide/link to best practices)

Any ideas? (:

ValueError when using GMM instead of HDBSCAN

Thanks @ktrapeznikov, this works like a charm. (:
