Error: ValueError: Expected 1D or 2D array, got 0D array instead

Dear scrublet developer,

I'm using srublet to detect doublets in my scRNA-seq sample. I've successfully used it in other samples but one that causes the following error. I'm wondering if you could help to solve the problem.

Thank you!
