[QUESTION] Memory footprint about comet

[vince62s]

Hmm that seems like either the model is not converging or your ground truth is all the same scores.

it's the plain wmt 2020 da csv file

ok, with miniLM learning_rate needs to be much higher and it works fine with 2020 data.

[ricardorei]

You mean the DA's from WMT 22? Some years of WMT are known to have very noisy DA's. For WMT 22 I would not use the DA's... For WMT you have the SQM data or the MQM from the metrics task... the DA's from WMT 2022 were collected only into english and are known to be noisy.

[ricardorei]

Its too big. Ill share it by email

[ricardorei]

You can train an XLMRoberta-large on a 24GB if you keep the embeddings frozen. XLM-R embeddings take a lot of space. But keeping them frozen has no impact on performance and reduces memory a lot.

[vince62s]

How do I do that? is it documented somewhere?
EDIT: found it but they were frozen already ....

also is the exact same 1720-da.csv dataset downladable somewhere? cause I am running tests independently wit 17, 18, 19 but with 20 I am getting this error: (encoder is miniLM)

Also you should use precision at 16.

To keep embeddings frozen just keep this flag at true.

[ricardorei]

Hmm that seems like either the model is not converging or your ground truth is all the same scores.

You can find the data here

[vince62s]

embedding frozen is already set to true in the unified_metric.yaml so not helping.
When I set precision: 16, I am getting a warning saying it's better to use 16-mixed for AMP.
I'll try 16 but I think I got an error with 16 only.

[dmar1n]

Hi @vince62s,

The precision value I currently use to avoid the warning is 16-mixed (following this). Also, you might want to try with nr_frozen_epochs: 1.0 and a bigger value for accumulate_grad_batches.

Hope this helps.

Hope this helps.

the memory issue appears as soon as the encoder is no longer frozen. so to test (to avoid waiting) I put nr_frozen_epochs=0.0 so that I see rigth away if things fit in the vRam.
with precision:16 / batch_size 4 we are a the very limit of 24GB, would be a pity if it crashes. there could be twp nice options: 1) have a filtertoolong catch to exclude examples taht are very long and tirgger this, and 2) a try/except when it goes OOM so that it can discard the batch and continue.

@ricardorei can you share the script that computes those csv files ? I would like to redo the same but exclude some specific systems, or do you have the same with the system name as a column?

[ricardorei]

I actually found the notebooks I used...but I did not saved the data. Just the raw notebooks. They should help you redo the data

Archive.zip

[ricardorei]

they also point to the previous WMT websites where you can download the data.

[vince62s]

Thanks, in the meantime I managed to do it for wmt2021. I was able to exclude one system but it gives me the same results.

I still have an issue with wmt22 data whatever the learning rate when training only on those data it does not converge.

[vince62s]

but here: https://huggingface.co/datasets/RicardoRei/wmt-da-human-evaluation
it has some 2022 data, is it DA or something else?
I trained on the 2022 extract from there so must be DA

[ricardorei]

yes exactly. Its those DA's from WMT 22

[ricardorei]

Usually I only use DA's from 2017 to 2020. Even those from 2021 I don't trust too much

[vince62s]

but do you have the exact data set used for wmt23-cometkiwi-da-xl and for wmt22-cometkiwi-da ?

[ricardorei]

Yes I do. Let me download it and I'll share here.

Its basically WMT 17 to 20 + MLQE-PE data.

[vince62s]

closing this but training with xlmroberta large or XL is still an issue with 24GB vram
maybe using Lora would help and be the solution.
