AttributeError: 'DynamicCache' object has no attribute 'detach'

Seems to happend when the model's output's past_key_values are an empty DynamicCache.

Expected behavior

Should properly reach the custom_metrics and terminate cleanly.

The text was updated successfully, but these errors were encountered:

NielsRogge · 2024-05-03T07:41:41Z

I had the same error and fixed it by using model.config.use_cache=False during training. But @VictorSanh might know a better option

EloiEynard · 2024-05-03T12:41:25Z

I had the same error and fixed it by using model.config.use_cache=False during training

That fixes this issue as the past_key_values are now full tensors.
But leads to a new error :

NielsRogge · 2024-05-03T16:18:35Z

Yes this is due to batches having different lengths of input_ids (in the code snippet of your first message, you set padding=True which means dynamic padding, each batch may have a different length). If your eval batch size is smaller than or equal to your training batch size, then it's fine.

It can be fixed by either padding all examples to the same length (i.e. using padding="max_length", max_length=200, truncation=True for instance), or by passing the flag eval_do_concat_batches=False to the TrainingArguments). In the latter case, you'll get a list of predictions/labels in the compute_metrics function rather than stacked tensors, so you would need to adapt your compute_metrics function accordingly.

I had the same error and fixed it by using model.config.use_cache=False during training. But @VictorSanh might know a better option

I don't have a better fix!

I think the cache problem should be fixed by converting DynamicCache back to legacy_cache in Idefics2's backbone language model, like it's already done in llama.

These changes are partially related to issue of making language models "compile" compatible, and should be available soon 🤗

Thanks for the explanation @zucchini-nlp! Does this mean that this fix won't be needed soon, or that it enables something which isn't available yet but will be soon?

zucchini-nlp · 2024-05-08T07:34:14Z

We discussed this with @gante the cache input-output format yesterday. Maybe llama-format cache is not what we need, by anyway @gante will take care of it 😄

amyeroberts · 2024-05-08T09:01:17Z

@zucchini-nlp OK. The main thing to know is what, if anything, should be updated in idefics2. Is what @gante is doing addressing this?

zucchini-nlp · 2024-05-08T09:39:50Z

@amyeroberts I am not sure what should be the correct format of cache objects we return for language models since now we do not have consistency, so I wanted @gante to look at it.

There are two options for this:

The language model should always return a tuple type cache (as current Llama), in which case we would have to only update Mistral to follow the same logic
The language model should return the same type of cache as it received in forward. In that case Idefics2 has to add cache.to_legacy_cache() in the end by ensuring it returns a tuple type, which will be consistent with how caching works for most current language models.

Also I believe we are going to get rid of the tuple type cache sometime in the future, so cache+Trainer is something to have in mind for then

amyeroberts · 2024-05-08T09:45:01Z

@zucchini-nlp OK, great, thanks for explaining. Let's leave as-is and then once the cache format is standardized we can propogate this to idefics2 + other models.

Hi @EloiEynard I just uploaded an example notebook for fine-tuning Idefics2 on an image -> JSON dataset here: https://github.com/NielsRogge/Transformers-Tutorials/blob/master/Idefics2/Fine_tune_Idefics2_for_JSON_extraction_use_cases_(PyTorch_Lightning).ipynb

EloiEynard · 2024-05-08T12:27:49Z

Thanks @NielsRogge, I got it all figured out with the Trainer and am currently finetuning with my custom eval. Wish I knew about lightning earlier though, seems more explicit.

By the way, if you don't mind me asking, I've noticed in your notebooks you use
model.add_adapter(lora_config)
model.enable_adapters()
Where I mostly used to see model = get_peft_model(model, lora_config)
Is there any difference between these two ? Thanks

NielsRogge · 2024-05-08T12:35:20Z

I had the same question, turns out both are equivalent. The get_peft_model API is recommended as it returns a PeftModel which has additionally utility methods such as save_adapter() with support for saving resized embedding layers. I tried leveraging it, but for some reason I gave me out-of-memory errors which I did not encounter with add_adapter. This could be due to PyTorch Lightning, the fact that I was using a notebook, or something else.

I'm currently looking into creating a similar notebook that leverages the Trainer API with get_peft_model. The reason I used PyTorch Lightning is because it allowed me to get up and running very quickly, especially regarding computing metrics during evaluation.

EloiEynard · 2024-05-08T12:53:17Z

I see, thanks for the details !
