Trajectory Batch Sampling For Training

via “gradient-accumulation-and-effective-batch-size-scaling”

PyTorch training framework — distributed training, mixed precision, reproducible research.

Unique: Automatically handles gradient accumulation by skipping optimizer.step() for intermediate batches and synchronizing gradients at the right intervals. Integrates with the Trainer's training loop to ensure gradient accumulation works correctly with distributed training and mixed precision.

vs others: More transparent than manual gradient accumulation (no need to manually skip optimizer steps) and more flexible than fixed batch size approaches (supports dynamic accumulation schedules). Integrates seamlessly with distributed training, whereas manual accumulation requires careful synchronization logic.
