This is the converted model from Unbabel/wmt23-cometkiwi-da

Just kept the weights/bias keys()
Renamed the keys to match the original Facebook/XLM-roberta-XL
kept the layer_wise_attention / estimator layers

Because of a hack in HF's code I had to rename the "layerwise_attention.gamma" key to "layerwise_attention.gam"

I changed the config.json key "layer_transformation" from sparsemax to softmax because there is a bug in COMET since the flag is not passed, the actual function used is the default which is softmax.

Usage:

from transformers import XLMRobertaTokenizer, XLMRobertaTokenizerFast, AutoModel
tokenizer = XLMRobertaTokenizerFast.from_pretrained("vince62s/wmt23-cometkiwi-da-roberta-xl", trust_remote_code=True)
model = AutoModel.from_pretrained("vince62s/wmt23-cometkiwi-da-roberta-xl", trust_remote_code=True)

text = "Hello world!</s></s>Bonjour le monde"
encoded_text = tokenizer(text, return_tensors='pt')
print(encoded_text)
output = model(**encoded_text)
print(output[0])

{'input_ids': tensor([[    0, 35378,  8999,    38,     2,     2, 84602,    95, 11146,     2]]), 'attention_mask': tensor([[1, 1, 1, 1, 1, 1, 1, 1, 1, 1]])}
tensor([[0.8217]], grad_fn=<AddmmBackward0>)

Let's double check with the original code from Unbabel Comet:

from comet import download_model, load_from_checkpoint
model = load_from_checkpoint("/home/vincent/Downloads/cometkiwi23/checkpoints/model.ckpt") # this is the Unbabel checkpoint
data = [{"mt": "Hello world!", "src": "Bonjour le monde"}]
output = model.predict(data, gpus=0)
print(output)

Prediction([('scores', [0.8216837048530579]), ('system_score', 0.8216837048530579)])

This is a COMET quality estimation model: It receives a source sentence and the respective translation and returns a score that reflects the quality of the translation.

Paper

CometKiwi: IST-Unbabel 2022 Submission for the Quality Estimation Shared Task (Rei et al., WMT 2022)

License:

cc-by-nc-sa-4.0

Usage (unbabel-comet)

Using this model requires unbabel-comet to be installed:

bash

pip install --upgrade pip  # ensures that pip is current 
pip install "unbabel-comet>=2.0.0"

Make sure you acknowledge its License and Log in into Hugging face hub before using:

bash

huggingface-cli login
# or using an environment variable
huggingface-cli login --token $HUGGINGFACE_TOKEN

Then you can use it through comet CLI:

comet-score -s {source-input}.txt -t {translation-output}.txt --model Unbabel/wmt22-cometkiwi-da

Or using Python:

python

from comet import download_model, load_from_checkpoint

model_path = download_model("Unbabel/wmt22-cometkiwi-da")
model = load_from_checkpoint(model_path)
data = [
    {
        "src": "The output signal provides constant sync so the display never glitches.",
        "mt": "Das Ausgangssignal bietet eine konstante Synchronisation, so dass die Anzeige nie stört."
    },
    {
        "src": "Kroužek ilustrace je určen všem milovníkům umění ve věku od 10 do 15 let.",
        "mt": "Кільце ілюстрації призначене для всіх любителів мистецтва у віці від 10 до 15 років."
    },
    {
        "src": "Mandela then became South Africa's first black president after his African National Congress party won the 1994 election.",
        "mt": "その後、1994年の選挙でアフリカ国民会議派が勝利し、南アフリカ初の黒人大統領となった。"
    }
]
model_output = model.predict(data, batch_size=8, gpus=1)
print (model_output)

Intended uses

Our model is intented to be used for reference-free MT evaluation.

Given a source text and its translation, outputs a single score between 0 and 1 where 1 represents a perfect translation.
