  ## 简介 Brief Introduction
  
  善于处理摘要任务，在数个中文摘要数据集上微调后的，中文版的PAGASUS-large。
  
  Good at solving text summarization tasks, after fine-tuning on multiple Chinese text summarization datasets, Chinese PAGASUS-large.

  ## 模型信息 Model Information
  
  参考论文：[PEGASUS: Pre-training with Extracted Gap-sentences for Abstractive Summarization](https://arxiv.org/pdf/1912.08777.pdf)
  
  基于[Randeng-Pegasus-523M-Chinese](https://huggingface.co/IDEA-CCNL/Randeng-Pegasus-523M-Chinese)，我们在收集的7个中文领域的文本摘要数据集（约4M个样本）上微调了它，得到了summary版本。这7个数据集为：education, new2016zh, nlpcc, shence, sohu, thucnews和weibo。
  
  Based on [Randeng-Pegasus-523M-Chinese](https://huggingface.co/IDEA-CCNL/Randeng-Pegasus-523M-Chinese), we fine-tuned a text summarization version (summary) on 7 Chinese text summarization datasets, with totaling around 4M samples. The datasets include: education, new2016zh, nlpcc, shence, sohu, thucnews and weibo.

  ## 使用 Usage
  
  ```python
  
  from transformers import PegasusForConditionalGeneration
  # Need to download tokenizers_pegasus.py and other Python script from Fengshenbang-LM github repo in advance,
  # or you can download tokenizers_pegasus.py and data_utils.py in https://huggingface.co/IDEA-CCNL/Randeng_Pegasus_523M/tree/main
  # Strongly recommend you git clone the Fengshenbang-LM repo:
  # 1. git clone https://github.com/IDEA-CCNL/Fengshenbang-LM
  # 2. cd Fengshenbang-LM/fengshen/examples/pegasus/
  # and then you will see the tokenizers_pegasus.py and data_utils.py which are needed by pegasus model
  from tokenizers_pegasus import PegasusTokenizer
  
  model = PegasusForConditionalGeneration.from_pretrained("IDEA-CCNL/Randeng-Pegasus-523M-Summary-Chinese")
  tokenizer = PegasusTokenizer.from_pretrained("IDEA-CCNL/Randeng-Pegasus-523M-Summary-Chinese")
  
  text = "据微信公众号“界面”报道，4日上午10点左右，中国发改委反垄断调查小组突击查访奔驰上海办事处，调取数据材料，并对多名奔驰高管进行了约谈。截止昨日晚9点，包括北京梅赛德斯-奔驰销售服务有限公司东区总经理在内的多名管理人员仍留在上海办公室内"
  inputs = tokenizer(text, max_length=1024, return_tensors="pt")
  
  # Generate Summary
  summary_ids = model.generate(inputs["input_ids"])
  tokenizer.batch_decode(summary_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
  
  # model Output: 反垄断调查小组突击查访奔驰上海办事处，对多名奔驰高管进行约谈
