When trying to visualize some sample data from the train_loader that generated using torch.utils.data.DataLoader(train_data, batch_size=64, shuffle=True) method i found that the generated image with its corresponding labels dose not match the actual classes images in the dataset .
example:
here, i visualize the first two images in the tainloader and they have 81 and 12 as labels.
