1.Autograd (automatic gradient algorithm)
autograd is the core package of PyTorch to implement the automatic gradient algorithm mentioned earlier. Let's start by introducing the variables.
autograd.Variable is the encapsulation of Tensor. Once we have defined the final variable (i.e., calculated loss, etc.), we can call its backwa ...

Firstly, the cross entropy loss function of torch is called as follows:
torch.nn.functional.cross_entropy(input, target, weight=None, size_average=None, ignore_index=-100, reduce=None, reduction='mean')
It is usually written as:
import torch.nn.functional as F
2. Parameter description
