Img_ir variable img_ir requires_grad false

Witryna26 lis 2024 · I thought gradients were supposed to accumulate in leaf_variables and this could only happen if requires_grad = True. For instance, weights and biases of layers such as conv and linear are leaf variables and require grad and when you do backward, grads will be accumulated for them and optimizer will update those leaf variables. Witryna每个Variable都有两个属性,requires_grad和volatile, 这两个属性都可以将子图从梯度计算中排除并可以增加运算效率 requires_grad:排除特定子图,不参与反向传播的计算,即不会累加记录grad volatile: 推理模式, 计算图中只要有一个子图设置为True, 所有子图都会被设置不参与反向传 播计算,.backward ()被禁止

Volatile = now has no effect. Use `with torch.no_grad():` instead
