The PyTorch DataLoader class is an efficient implementation of an iterator that can perform useful preprocessing and returns batches of elements. Here, we use its ability to batch and shuffle data, but DataLoaders are capable of much more. Note that each time we iterate over a DataLoader, it starts again from the beginning. how tall is class 1a in feet
