After I applied deepspeed, I could increase the batch size (64 -> 128, but OOM with 256) of training model so I expected train time would decrease. However, even though I applied deepspeed in my code, the train time is the same.

SpletEach training step can trigger an OOM error if the tensors (training batch, weights, gradients, etc.) allocated during the steps have a too large memory footprint. If an OOM error is encountered, decrease batch size else increase it. How much the batch size is increased/decreased is determined by the chosen strategy. SpletIt is not necessary to clear the gradient every time as with PyTorch’s trainer.zero_grad() because by default the new gradient is written in, not accumulated. You need to specify the update step size (usually batch size) when performing step() on the trainer. You need to call .asscalar() to turn a multidimensional array into a scalar.
