Pytorch backward hook example

WebWe introduce hooks for this purpose. You can register a function on a Module or a Variable. The hook can be a forward hook or a backward hook. The forward hook will be executed when a forward call is executed. The backward hook will be executed in the backward phase. Let’s look at an example. We register a forward hook on conv2 and print some ...

WebThus, by default, backward () is called on a scalar tensor and expects no arguments. For example: a = torch.tensor ( [ [1,2,3], [4,5,6]], dtype=torch.float, requires_grad=True) for i in range (2): for j in range (3): out = a [i,j] * a [i,j] out.backward () print (a.grad) yields tensor ( [ [ 2., 4., 6.], [ 8., 10., 12.]]) http://python1234.cn/archives/ai30149 black guy smiling frown https://lixingprint.com
