Error, return zero for all userCode, itemCode and rating values!

[sososa1213]

I need to retrieve values of userCode, itemCode and rating from "/movielens/ml-100k/ratings.txt".
I use this way

Resource resource = new Resource("librec.properties");
Configuration conf = new Configuration();
conf.addResource(resource);
Randoms.seed(1);
TextDataModel dataModel = new TextDataModel(conf);
dataModel.buildDataModel();
SparseMatrix trainMatrix = dataModel.getDataSplitter().getTrainData();
int count = trainMatrix.numRows();
 for (int i : trainMatrix.rows()) {
           	int userCode = (int) trainMatrix.get(i,0);
		int itemCode = (int) trainMatrix.get(i, 1);
		double rating = trainMatrix.get(i, 2);
}

when I print values is zero.
Any help to fix this error
