Nettet30. nov. 2024 · Dataset Information. The MNIST dataset contains 28 by 28 grayscale images of single handwritten digits between 0 and 9. The set consists of a total of 70,000 images, the training set having 60,000 and the test set has 10,000. This means that there are 10 classes of digits, which includes the labels for the numbers 0 to 9. http://whatastarrynight.com/machine%20learning/python/Constructing-A-Simple-CNN-for-Solving-MNIST-Image-Classification-with-PyTorch/
