Webb18 feb. 2024 · 6. I have since moved on to use the native "ddp" with multiprocessing in PyTorch. As far as I understand, PytorchLightning (PTL) is just running your main script multiple times on multiple GPU's. This is fine if you only want to fit your model in one call of your script. However, a huge drawback in my opinion is the lost flexibility during the ... Webb14 mars 2024 · FSDP is a type of data-parallel training, but unlike traditional data-parallel, which maintains a per-GPU copy of a model’s parameters, gradients and optimizer states, it shards all of these states across data-parallel workers and can optionally offload the sharded model parameters to CPUs. northampton cycle clubWebbSharded Data Parallel. Wrap the model, and reduce the gradients to the right rank during the backward pass. wrap the base model with a model which knows where to reduce each gradient. add an autograd function which calls the model grad dispatch on the way back. the sharded optimizer (s) which will decide the gradient partitioning. how to repair protemp heater
