To include batch size in PyTorch basic examples, the easiest and cleanest way is to use PyTorch torch.utils.data.DataLoader and torch.utils.data.TensorDataset. Dataset stores the samples and their corresponding labels, and DataLoader wraps an iterable around the Dataset to enable easy access to the samples.
