For data in train_loader: break
WebJul 15, 2024 · You can set number of threads for data loading. trainloader=torch.utils.data.DataLoader (trainset, batch_size=32, shuffle=True, num_workers=8) testloader=torch.utils.data.DataLoader (testset, batch_size=32, shuffle=False, num_workers=8) For training, you just enumerate on the data loader. WebFor data loading, passing pin_memory=True to the DataLoader class will automatically put the fetched data tensors in pinned memory, and thus enables faster data transfer to CUDA-enabled GPUs. In the next section we’ll learn about Transforms, which define the preprocessing steps for loading the data.
