Research direction
Start by tracing RepeatingLoader through the trainer and pipe-stage handling, then inspect how num_train_steps is compared with num_iters, defined as len(train_dataloader)//gradient_accumulation_steps. Reproduce the failure with num_train_steps greater than num_iters and verify that intermediate pipe stages remain valid and training completes without the reported failure.
