# Bert-mini2Bert-mini Summarization with 🤗EncoderDecoder Framework

This model is a warm-started *BERT2BERT* ([mini](https://huggingface.co/google/bert_uncased_L-4_H-256_A-4)) model fine-tuned on the *CNN/Dailymail* summarization dataset.

The model achieves a **16.51** ROUGE-2 score on *CNN/Dailymail*'s test dataset.

For more details on how the model was fine-tuned, please refer to

## Model in Action 🚀

```python
from transformers import BertTokenizerFast, EncoderDecoderModel
import torch
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
tokenizer = BertTokenizerFast.from_pretrained('mrm8488/bert-mini2bert-mini-finetuned-cnn_daily_mail-summarization')
model = EncoderDecoderModel.from_pretrained('mrm8488/bert-mini2bert-mini-finetuned-cnn_daily_mail-summarization').to(device)

def generate_summary(text):
    # cut off at BERT max length 512
    inputs = tokenizer([text], padding="max_length", truncation=True, max_length=512, return_tensors="pt")
    input_ids = inputs.input_ids.to(device)
    attention_mask = inputs.attention_mask.to(device)

    output = model.generate(input_ids, attention_mask=attention_mask)

    return tokenizer.decode(output[0], skip_special_tokens=True)
  
text = "your text to be summarized here..."
generate_summary(text)
```
