Which code is this in? If you are reading centroids from a file, it seems that you are just classifying points which should not be done with updates.
If you are reading points from a file and creating/updating centroids, then the centroids should be created as dense vectors. Either way, I don't see how you have this problem. Clearly you do, however, so my understanding of the goal is probably missing.
