SpletFor example, if you have 4 GPUs and use per_device_train_batch_size=12 and gradient_accumulation_steps=3 you will have an effective batch size of 4*12*3=144. The Trainer allows for distributed training and if you execute your Trainer training script on a machine with multiple GPUs it will automatically utilize all of them, hence the name per ...

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. Splet28. okt. 2024 · Since Trainer handles both batch_size and gradient_accumulation_steps it seems like it could detect some out-of-memory situations and handle those scenarios …
