WebIn autograd, if any input Tensor of an operation has requires_grad=True, the computation will be tracked. After computing the backward pass, a gradient w.r.t. this tensor is … In PyTorch, the Tensor class has a grad_fn attribute. This references the operation used to obtain the tensor: for instance, if a = b + 2, a.grad_fn will be AddBackward0. But what does "reference" mean exactly? Inspecting AddBackward0 using inspect.getmro (type (a.grad_fn)) will state that the only base class of AddBackward0 is object. Web自动求梯度. Pytorch提供的autograd包能够根据输入和前向传播过程自动构建计算图，并执行反向传播。.
