Hello, 
Facing the same issue while using https://github.com/huggingface/transformers/tree/master/examples/tensorflow/translation for finetuning MarianMT's opus-mt-en-hi model.

<|||||>@Rocketknight1, wondering if there is any update on this issue.<|||||>@Rocketknight1 - could you take a look? :-)<|||||>I tested this simple fix, and it seems to work. In _run_summarization.py_, I added the line to remove ```decoder_input_ids``` from the batch dictionary (see below). My guess is that duplicate copies of ```decoder_input_ids``` are being passed to `prepare_inputs_for_generation()` function, after invoking ```model.generate(**batch)```.  

```
if training_args.do_eval:
            logger.info("Evaluation...")
            for batch, labels in tqdm(
                tf_eval_dataset, total=len(eval_dataset) // training_args.per_device_eval_batch_size
            ):
             decoder_input_ids = batch.pop("decoder_input_ids", None)
```



@patrickvonplaten and @Rocketknight1 could you confirm if the change looks good to you and the fix doesn't break the BART model inference logic?

You're correct that supplying `decoder_input_ids` seems to break `generate()`. Your solution to `pop()` that key from the dictionary probably fixes the issue, but the underlying problem is that `generate()` simply doesn't know what to do with a `decoder_input_ids` input key. We're currently in the middle of entirely refactoring our TF `generate()` function for performance/bugfixing reasons, so I'll put that in the list of stuff to be investigated there, but I don't have a timeline on it unfortunately.

In the meantime, if you want to submit a PR with that change, please do! However, it will definitely only be a temporary workaround until we figure things out properly.<|||||>Thank you for confirming the fix @Rocketknight1 . Could you point me to the PR submission instructions, I will submit the fix and I will add a comment that it is a temporary fix. <|||||>Hi @bpraveenk, thanks for the offer!
