This article introduces the relevant knowledge of "what is the gradient tailoring method of pytorch". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

I won't say much nonsense. Let's look at the example.

Import torch.nn as nnoutputs = model (data) loss= loss_fn (outputs, target) optimizer.zero_grad () loss.backward () nn.utils.clip_grad_norm_ (model.parameters (), max_norm=20, norm_type=2) optimizer.step ()

Parameters of nn.utils.clip_grad_norm_:

Parameters-A variable-based iterator that normalizes gradients

Maximum norm of max_norm-gradient

Norm_type-specifies the type of norm, default to L2
