In this example, we will ues MNIST dataset. Example - 1 - DataLoaders with Built-in Datasets. ArgumentParser (description = "PyTorch MNIST Example") parser. Neural networks train better when the input data is normalized so that the data ranges from -1 to 1 or 0 to 1. This tutorial will walk you through building a simple MNIST classifier showing PyTorch and PyTorch Lightning code side-by-side. It's easy to define the loss function and compute the losses: loss_fn = nn.CrossEntropyLoss () #training process loss = loss_fn (out, target) Viewing Results The result of this example is simply the accuracy of the model that is trained to determine whether an image was part of the original training set. For example, a torch.randn ( (1, 2)) creates a 1x2 tensor, or a 2-dimensional row vector. # init our model mnist_model = mnistmodel() # init dataloader from mnist dataset train_ds = mnist(path_datasets, train=true, download=true, transform=transforms.totensor()) train_loader = dataloader(train_ds, batch_size=batch_size) # initialize a trainer trainer = trainer( accelerator="auto", devices=1 if torch.cuda.is_available() else none, # A simple example showing how to explain an MNIST CNN trained using PyTorch with Deep Explainer.
