WebExp 函数的前向很简单,直接调用 tensor 的成员方法exp即可。反向时,我们知道 \frac{\partial e^x}{\partial x} = e^x, 因此我们直接使用 e^x 乘以grad_output即得梯度。 我们发现,我们自定义的函数Exp正确地进行了前向与反向。同时我们还注意到,前向后所得的结果包含了grad_fn属性,这一属性指向用于计算其 ...
WebApr 21, 2024 · Hey @albanD, I tried to let grad point to DDP bucket buffers, in this case, variable.grad() will be view/slice of bucket buffers. I tried to call optimizer.zero_grad() after that, it failed because view can not call detach_(). But I tried to call detach() in optimizer.zero_grad(), it worked fine.
