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.

11.07.2019 · One tip that may help, is to check the grad_fn of the tensor which is missing the _trt attribute. This is set for any non-leaf tensor requiring gradient. I believe you can check this by. Attempt conversion (should throw error) model_trt = torch2trt ( …
Nov 14, 2019 · Disable autograd while you update your weights to avoid the second one. Here is the new code update: for i in range (epochs): predict = torch.mm (feature, weight) + bias.item () loss = torch.sum (predict - label, dim=0) loss.backward () # Disable the autograd with torch.no_grad (): # Inplace changes weight.sub_ (weight.grad*lr) bias.sub_ (bias ...

Mar 17, 2019 · Hi, I found this this code to zero the gradients on single parameter: a.grad.zero_() But it is not working: AttributeError: 'NoneType' object has no attribute 'zero_' I previously declared: a = torch.tensor(-1., requires_grad=True) a = nn.Parameter(a)
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)

24.01.2019 · Liangtaiwan commented on Jan 24, 2019. The gradient of the tensor may be None, if the tensor is forward, but do not backward. 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.
The code was change from zero_gradients(x) to x.zero_grad(), which will cause the "AttributeError: 'Tensor' object has no attribute 'zero_grad'" error in ...
