叶子节点和tensor的requires_grad参数 - 知乎
https://zhuanlan.zhihu.com/p/85506092
自己定义的tensor的requires_grad属性默认为False,神经网络层中的权值w的tensor的requires_grad属性默认为True。需要说明,如果自行定义了一个tensor并将其requires_grad设置为True,该tensor是叶子节点,且依赖该tensor的其他tensor是非叶子节点(非叶子节点不会自动求导),其requires_grad自动设置为True,这样便形成 ...

Mar 31, 2021 · w1 = w1 - w1.grad*0.001 is reassigning w1, so afterwards w1 no longer refers to the same tensor it did before. To maintain all the internal state of w1 (e.g. the .grad member) you must update w1 in place. Since this is a leaf tensor we also need to disable construction of the computation graph. with torch.no_grad(): w1.sub_(w1.grad * 0.001)

'NoneType' object has no attribute 'zero_' - autograd ...
https://discuss.pytorch.org/t/nonetype-object-has-no-attribute-zero/61013
14.11.2019 · Hi, When you do weight = weight - weight.grad*lr, weight now points to a brand new Tensor and so the gradient informations from the original weight Tensor are gone. You can check that after this line, weight.grad is None. The other problem you’re going to encounter is that weight = weight - XXX, this will be tracked by the autgrad which you most likely don’t want.

For example, I'm using BERT to finetune a model with the last second enocded_layer. The last layer is calculated when forward, however, it's not gradient do not be calculated when backward.
