## 简介 Brief Introduction

在Randeng-T5-77M的基础上，收集了100个左右的中文数据集，进行Text2Text统一范式的有监督任务预训练。

On the basis of Randeng-T5-77M, about 100 Chinese datasets were collected and pre-trained for the supervised task of Text2Text unified paradigm.

## 模型信息 Model Information

参考论文：[Exploring the Limits of Transfer Learning with a Unified Text-to-Text Transformer](http://jmlr.org/papers/v21/20-074.html)

基于[Randeng-T5-77M](https://huggingface.co/IDEA-CCNL/Randeng-T5-77M)，我们在收集的100+个中文领域的多任务数据集（从中采样了30w+个样本）上微调了它，得到了此多任务版本。这些多任务包括：情感分析，新闻分类，文本分类，意图识别，自然语言推理，多项选择，指代消解，抽取式阅读理解，实体识别，关键词抽取，生成式摘要。

Based on [Randeng-T5-77M](https://huggingface.co/IDEA-CCNL/Randeng-T5-77M), we fine-tuned it on a collection of 100+ multitasking datasets in Chinese domains (from which 30w+ samples were sampled) to obtain this multitasking version. These multitasks include: sentiment analysis, news classification, text classification, intention recognition, natural language inference, multiple choice, denotational disambiguation, extractive reading comprehension, entity recognition, keyword extraction, and generative summarization.


## 使用 Usage

```python
import torch
from transformers import T5Tokenizer, T5Config, T5ForConditionalGeneration

# load tokenizer and model 
pretrained_model = "IDEA-CCNL/Randeng-T5-77M-MultiTask-Chinese"

special_tokens = ["<extra_id_{}>".format(i) for i in range(100)]
tokenizer = T5Tokenizer.from_pretrained(
    pretrained_model,
    do_lower_case=True,
    max_length=512,
    truncation=True,
    additional_special_tokens=special_tokens,
)
config = T5Config.from_pretrained(pretrained_model)
model = T5ForConditionalGeneration.from_pretrained(pretrained_model, config=config)
model.resize_token_embeddings(len(tokenizer))
model.eval()

# tokenize
text = "情感分析任务：【房间还是比较舒适的,酒店服务良好】这篇文章的情感态度是什么？正面/负面"
encode_dict = tokenizer(text, max_length=512, padding='max_length',truncation=True)

inputs = {
  "input_ids": torch.tensor([encode_dict['input_ids']]).long(),
  "attention_mask": torch.tensor([encode_dict['attention_mask']]).long(),
  }

# generate answer
logits = model.generate(
  input_ids = inputs['input_ids'],
  max_length=100, 
  early_stopping=True,
  )

logits=logits[:,1:]
predict_label = [tokenizer.decode(i,skip_special_tokens=True) for i in logits]
print(predict_label)

# model output: 正面
```
