Currently I have a training set, with inputs X being N d-dimensional data, and outputs Y being a N-by-N matrix (which measures some pairwise distances among these data).  I am trying to create batch training data for a neural network, and I know that for input X I can do following to generate batch inputs of size n:
batch = DataLoader(X, batch_size=n, shuffle=True, drop_last=True)
Does anyone know how to generate the batch output matrix of size n-by-n for output Y while keeping the indices for X and Y consistent?
Thank you!
