Hi,
.num_exapmples returns the number of datapoints in the dataset. In other words, it's the dataset size.
In this code, we want to create a validation dataset that is 10% of the size of the training dataset. So, the size of the validation set would be validation_size = 0.1*training_size
training_size in this case is mnist_info.splits['train'].num_examples
Best,
