Description

Hi!

When I try to run bertopic() I get the following error:

TypeError: Cannot use scipy.linalg.eigh for sparse A with k >= N. Use scipy.linalg.eigh(A.toarray()) or reduce k.

I increased the number of documents to 205504, which should be enough I think.

Does someone have any idea what could cause the problem?

Research direction

Start by reproducing the error from bertopic() with the reported document scale and inspect the scipy.linalg.eigh failure for sparse A when k >= N. Determine which input or parameter relationship causes the condition, then confirm a documented or tested resolution that avoids the reported TypeError.
