I should note that I’m using deepspeed not so much for training a big model (roberta-base is not that big) but rather to try to jam large batch sizes onto the GPUs to …

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 ...
