off-the-shelf tool for sparse NMF

Hi,

I have a very sparse matrix I need to factorize. Does anyone know of a good (and fast) tool for sparse nmf? I need something that I can run as a single command (hopefully a binary or a python library).

Previously I used to run it from my Python script a binary written by Analytics1305, but the license expired, and I don't have the sources.

Thanks. Joel
