Deep Learning with PyTorch Quick Start Guide

Default value initialization

There are many cases where we need to initialize torch tensors to default values. Here, we create three 2 x 3 tensors, filling them with zeros, ones, and random floating point numbers:

An important point to consider when we are initializing random arrays is the so-called seed of reproducibility. See what happens when you run the preceding code several times. You get a different array of random numbers each time. Often in machine learning, we need to be able to reproduce results. We can achieve this by using a random seed. This is demonstrated in the following code:

Notice that when you run this code many times, ...
