UMAP.fit_transform(data) keep giving error "Buffer has wrong number of dimensions (expected 1, got 2)"

[akhilksingh]

I am trying to fit_transform data which was working earlier but installed the version again 0.3.10 and now I see every time this error, not sure why?

For me the only fix to this problem is to reduce the dataset-size.

Same issue as well, it used to work but now it doesn't.

Same. This started after I updated from scipy 1.1 to 1.5.4.

I had this error too, resolved after updating umap-learn, as suggested in https://github.com/lmcinnes/umap/issues/461#issuecomment-652500422

I had the same issue, thanks to @ksenia007 resolved after updating.

downgrading the scipy version solved my problem pip install scipy==1.2.3 pip install umap-learn==0.3.9
