Thanks for this. I did not know when Lightning syncs the gradients across GPUs/machines, and thought perhaps syncing is triggered only when an optimizer's step() method is called, and not when just doing the manual backward pass. If you could point us to the relevant bit of the docs or source code, it'll be really helpful. my music on pbs march 2018
