No convergence while estimating H with W fixed

[Glooow1024]

Hi rhgao,

Thanks for releasing your code. When I used your network to seperate audio sources, to get some .wav files as output, I realized a NMF algorithm estimating H with the W fixed by myself. But I found my program didn‘t seem to converge. So I want to know how did you compute H with W fixed? Do you know of any related libraries? I didn't found it in sklearn you mentioned in #1. Or did you realize it by yourself? And could you share your code?

Thank you very much! Waiting for your reply.
