# Chinese Pegasus

## Model description

This model is pre-trained by [UER-py](https://github.com/dbiir/UER-py/), which is introduced in [this paper](https://arxiv.org/abs/1909.05658). Besides, the models could also be pre-trained by [TencentPretrain](https://github.com/Tencent/TencentPretrain) introduced in [this paper](https://arxiv.org/abs/2212.06385), which inherits UER-py to support models with parameters above one billion, and extends it to a multimodal pre-training framework.

You can download the set of Chinese PEGASUS models either from the [UER-py Modelzoo page](https://github.com/dbiir/UER-py/wiki/Modelzoo), or via HuggingFace from the links below:

|                   |              Link              |
| ----------------- | :----------------------------: |
| **PEGASUS-Base** | [**L=12/H=768 (Base)**][base] |
| **PEGASUS-Large**  | [**L=16/H=1024 (Large)**][large] |

## How to use

You can use this model directly with a pipeline for text2text generation (take the case of PEGASUS-Base):

```python
>>> from transformers import BertTokenizer, PegasusForConditionalGeneration, Text2TextGenerationPipeline
>>> tokenizer = BertTokenizer.from_pretrained("uer/pegasus-base-chinese-cluecorpussmall")
>>> model = PegasusForConditionalGeneration.from_pretrained("uer/pegasus-base-chinese-cluecorpussmall")
>>> text2text_generator = Text2TextGenerationPipeline(model, tokenizer)  
>>> text2text_generator("内容丰富、版式设计考究、图片华丽、印制精美。[MASK]纸箱内还放了充气袋用于保护。", max_length=50, do_sample=False)
    [{'generated_text': '书 的 质 量 很 好 。'}]
```

## Training data

[CLUECorpusSmall](https://github.com/CLUEbenchmark/CLUECorpus2020/) is used as training data.

## Training procedure

The model is pre-trained by [UER-py](https://github.com/dbiir/UER-py/) on [Tencent Cloud](https://cloud.tencent.com/). We pre-train 1,000,000 steps with a sequence length of 512.
Taking the case of PEGASUS-Base

```
python3 preprocess.py --corpus_path corpora/cluecorpussmall_bert.txt \
                      --vocab_path models/google_zh_vocab.txt \
                      --dataset_path cluecorpussmall_pegasus_seq512_dataset.pt \
                      --processes_num 32 --seq_length 512 \
                      --data_processor gsg --sentence_selection_strategy random
```

```
python3 pretrain.py --dataset_path cluecorpussmall_pegasus_seq512_dataset.pt \
                    --vocab_path models/google_zh_vocab.txt \
                    --config_path models/pegasus/base_config.json \
                    --output_model_path models/cluecorpussmall_pegasus_base_seq512_model.bin \
                    --world_size 8 --gpu_ranks 0 1 2 3 4 5 6 7 \
                    --total_steps 1000000 --save_checkpoint_steps 100000 --report_steps 50000 \
                    --learning_rate 1e-4 --batch_size 8
```

Finally, we convert the pre-trained model into Huggingface's format:

```
python3 scripts/convert_pegasus_from_uer_to_huggingface.py --input_model_path models/cluecorpussmall_pegasus_base_seq512_model.bin-1000000 \                                                             
                                                           --output_model_path pytorch_model.bin \                                           
                                                           --layers_num 12
```
