WebJun 16, 2024 · Gradients are modified in-place. Arguments: parameters (Iterable [Tensor] or Tensor): an iterable of Tensors or a single Tensor that will have gradients normalized max_norm (float or int): max norm of the gradients norm_type (float or int): type of the used p-norm. Can be ``'inf'`` for kl_divergence June 17, 2024, 12:17pm #4 WebSorted by: 4 torch.nn.utils.clip_grad_norm_ performs gradient clipping. It is used to mitigate the problem of exploding gradients, which is of particular concern for recurrent networks (which LSTMs are a type of). Further details can be found in the original paper.

It usually improves the training (and is pretty much always done in the fine-tuning scripts of research papers), which is why we use it by default. Norm clipping is the most commonly use, you can always try alternatives and see if it yields better results. north anclote nature parkWebGradient clipping. During the training process, the loss function may get close to a cliffy region and cause gradient explosion. And gradient clipping is helpful to stabilize the training process. More introduction can be found in this page.
