Reproduction

I'm running Accelerate with TRL to train LLAMA 3 70B. It breaks with the above exception when it somehow gets huge max size inside PPOTrainer.step(). Any hints for what is wrong? Thanks

Main code:


    accelerator = Accelerator(
        kwargs_handlers=[
            InitProcessGroupKwargs(timeout=timedelta(minutes=30), backend="nccl")
        ]

    device = accelerator.device

    )
    # Tokenizer:
    tokenizer = AutoTokenizer.from_pretrained(context.model_name)
    tokenizer.pad_token_id = tokenizer.eos_token_id

    # Refs: llama-recipes: src/llama_recipes/finetuning.py
    # If there is a mismatch between tokenizer vocab size and embedding matrix,
    # throw a warning and then expand the embedding matrix
    if len(tokenizer) > model.pretrained_model.get_input_embeddings().weight.shape[0]:
        print(

    context.generation_kwargs |= dict(
        pad_token_id=tokenizer.pad_token_id,

    model.eval()
    with accelerator.main_process_first():

Expected behavior

It does the PPOTrainer.step() successfully.

did you get the correct answer? I have the same problem.

Dai0-2 avatar Aug 04 '24 14:08 Dai0-2

did you get the correct answer? I have the same problem.

@Dai0-2 No, I didn't find a solution to it. I think, I should have tried to supply padded tensors there, i.e. tensors of the same size. It can be padding on the left so all tensors have queries to the right. Then responses can be concatenated. Perhaps that can avoid this padding across devices that results in this exception.

I met the same error when use accelerate in evaluating the logits.
