How to optimize UMAP parameters for UMAP enhanced HDBSCAN clustering on 1536 dimension embeddings

I'd recommend starting with the advice on UMAP for clustering in the documentation: https://umap-learn.readthedocs.io/en/latest/clustering.html#umap-enhanced-clustering

Nans when following Re-training Parametric UMAP with landmarks tutorial

Hello! I think this might be related to changes in #1156 , it looks like the documentation hasn't been updated to reflect the new helper functions for adding landmarks. I've...

Nans when following Re-training Parametric UMAP with landmarks tutorial

After some testing today I mostly just confused myself. I found a couple of things: - When I first ran the notebook as is on the most recent version from...

Nans when following Re-training Parametric UMAP with landmarks tutorial

I have tried joachimpoutaraud's solution above, but unfortunately am still getting the nan loss.

Nan during GPU training

I tried to do some debugging on this today, and still ended up with more questions than answers. I have access to two different environments at the moment (linux VM,...

Nan during GPU training

Made some progress on this today. There seems to be an issue with some of the persistent states of the parametric_model, causing exploding gradients (in certain, non-deterministic ways). For now,...
