WebIt takes effect in both the forward and backward passes: During the forward pass, an operation is only recorded in the backward graph if at least one of its input tensors require grad. During the backward pass ( .backward () ), only leaf tensors with requires_grad=True will have gradients accumulated into their .grad fields.
