Is there good library to do NMF fast?

Question

I have a sparse matrix whose shape is 570000*3000. I tried nima to do NMF (using the default nmf method, and set max_iter to 65). However, I found nimfa very slow. Have anyone used a faster library(can be used by Python/R) or software to do NMF?

This question (Sparse matrix factorization with Nimfa is very slow with implicit zeros) shows that you might want to try the .todense() version of the code perhaps?
