hello, I'm using NMF_ANLS_BLOCKPIVOT algorithm on a 200x990 matrix with this code W1, H1, info1 = NMF_ANLS_BLOCKPIVOT().run(X1, 56, max_iter=500, verbose=1)
but after running for about 15 minutes, it shows an error for singular matrix:

numpy.linalg.linalg.LinAlgError: Singular matrix
I searched the singular matrix error and I got this error happens if a numpy matrix isn't invertible.
now what should I do?
sorry for my bad english and I thank you.
