Purpose

Take the PyTorch tutorial PyTorch: Tensors and autograd For reference, calculate the loss and weight using the PyTorch tensor and automatic differentiation (autograd) </ span>.

Previously, the gradient of neural network parameters was calculated without using the automatic differentiation function </ span> implemented in PyTorch, but PyTorch's automatic differentiation The (autograd) function allows you to easily </ span> the parameter gradient calculation </ span>.

For detailed explanation and code, please see "[PyTorch] Sample ③ ~ TENSORS AND AUTOGRAD ~" ..
