# XLM-RoBERTa model for English and Azerbaijani




## Usage (Sentence-Transformers)


```
pip install -U sentence-transformers
```


```python
from sentence_transformers import SentenceTransformer
sentences = ['Bu nümunə cümlədir', 'Bu cümlə bir nümunədir']

model = SentenceTransformer('LocalDoc/xlm-roberta-AZ')
embeddings = model.encode(sentences)
print(embeddings)
```



## Usage (HuggingFace Transformers)

```python
from transformers import AutoTokenizer, AutoModel
import torch



def mean_pooling(model_output, attention_mask):
    token_embeddings = model_output[0]
    input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
    return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)


sentences = ['Bu nümunə cümlədir', 'Bu cümlə bir nümunədir']


tokenizer = AutoTokenizer.from_pretrained('LocalDoc/xlm-roberta-AZ')
model = AutoModel.from_pretrained('LocalDoc/xlm-roberta-AZ')


encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')


with torch.no_grad():
    model_output = model(**encoded_input)


sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])

print("Sentence embeddings:")
print(sentence_embeddings)
```
