[PYTHON] [PyTorch] Sample ④ ~ Defining New autograd Functions (definition of automatic differential functions) ~

Purpose

PyTorch Tutorial [PyTorch: Defining New autograd Functions](https://pytorch.org/tutorials/beginner/examples_autograd/two_layer_net_custom_function.html#sphx-glr-beginner-examples-autograd-two-layer-net-custom-function- Calculate loss and weight using PyTorch tensor and automatic differentiation (autograd) </ span> with reference to py).

In the previous [PyTorch] sample ③ ~ TENSORS AND AUTOGRAD ~, the basics of automatic differentiation I introduced the handling.

This time, let's make the automatic differentiation code used last time into a function </ span>.

For detailed explanation and code, refer to "[PyTorch] Sample ④ ~ Defining New autograd Functions ~". Please look.
