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.

The gradient at the given point is a coefficient for adjusting weights during back-propagation. "Handle" is a general term for an object descriptor, designed to give appropriate access to the object.
