[PyTorch] Use “random_split()” Function To Split Data Set

WebApr 11, 2024 · random_split (dataset, lengths) works directly on the dataset. The function expects 2 input arguments. The first argument is the dataset. The second is a tuple of lengths. If we want to split our dataset into 2 parts, we will provide a tuple with 2 numbers. These numbers are the sizes of the corresponding datasets after the split. WebOct 20, 2024 · The data loading process in PyTorch involves defining a dataset class that inherits from data.Dataset. The class defines only what the data point at a given index is and how much data points there are. PyTorch can then handle a good portion of the other data loading tasks – for example batching.
