PyTorch的optimizer默认情况会自动对梯度进行accumulate,所以对下一次iteration(一个新的batch),需要对optimizer进行清空操作。每次.backward之前,需要注意叶子梯度节点是否清零,如果没有清零,第二次backward会累计上一次的梯度。 有如下代码: x = torch.tensor(1.0, requires_grad=True) y = torch.tensor(2.0, requires...

so if cilp_grad_norm_ is required then we can not use "Optimizer in backward"? 👍 1 awgu commented Oct 24, 2024 I think you would need to do something different mathematically, e.g. use previous iteration's total norm or clip each gradient separately. 👍 2 felipemello1 mentione...
The standard way to loop through the characters of astd::stringbackward is by using reverse iterators, as shown below. Since the iteration is read-only, we have used thestd::string::const_iteratorreturned bystd::string::crbeginandstd::string::crend. ...

Um rückwärts zu iterieren, können wir die Methoderange()verwenden und als erstes Argument einen Startindex wie z. B.100, als zweites Argument einen Stoppindex wie z. B.-1(da wir bis0iterieren wollen) und eine Schrittweite von-1übergeben, da die Iteration rückwärts erfolgt. ...

In the first iteration, `dist_prims.pack` creates buckets of greater than or equal to ``bucket_size_in_mb`` that are bunching up one or more gradient tensors. ``dist_prims.unpack`` writes out allreduce'd gradients to original gradient tensors....
