An Iterator is an object which is used to iterate over an iterable object using the __next__ method, which returns the next item of the object. A simple example is the following. Consider an iterable and use the next method to call the next item in the list. This will print the next item until the end of the list is reached. bowling alley on fort braggWebDataset stores the samples and their corresponding labels, and DataLoader wraps an iterable around the Dataset to enable easy access to the samples.
