Sometimes I find the results from rapids KNN and UMAP very weird. The majoy data points are in center and super small (see below). At the beginning I thought it is the data issue. Today I ran the same data, same parameters with rapids on and off. It shows totally different results and without rapids it looks like a normal UMAP. It seems the UMAP could break with rapids version with some data.
