WebJun 17, 2024 · Gradient Accumulation with JAX. I made a simple script to try to do gradient accumulation with JAX. The idea is to have large batch size (e.g. 64) that are split in small chunks (e.g. 4) that fit in the GPU's memory. For each chunck, the resulting gradient, stored in a pytree, is added to the current batch gradient. WebNov 21, 2024 · Gradient Clipping is All You Need ( docs) You can sometimes implement your own backprop, this can help when e.g. you combine 2 functions that saturate into one that doesn't, or to enforce values at singularities. Diagnose your backprop by inspecting the computational graph. Usually look for divisions, signaled with the div token:
