Pytorch lightning gradient clipping

WebMay 30, 2024 · In Lightning, the idea is that you organize the code in such a way that training logic is separated from inference logic. forward: Encapsulates the way the model would be used regardless of whether you are training or performing inference. training_step: Contains all computations necessary to produce a loss value to train the model. WebMar 3, 2024 · Gradient Clipping. Gradient clipping is a technique that tackles exploding gradients. The idea of gradient clipping is very simple: If the gradient gets too large, we rescale it to keep it small. More precisely, if ‖g‖ ≥ c, then. g ↤ c · g/‖g‖ where c is a hyperparameter, g is the gradient, and ‖g‖ is the norm of g.
