WebMay 22, 2015 · 403. The batch size defines the number of samples that will be propagated through the network. For instance, let's say you have 1050 training samples and you want to set up a batch_size equal to 100. The algorithm takes the first 100 samples (from 1st to 100th) from the training dataset and trains the network. Web5. 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.
