## 简介 Brief Introduction

2021年登顶FewCLUE和ZeroCLUE的中文BERT，在数个相似度任务上微调后的版本

This is the fine-tuned version of the Chinese BERT model on several similarity datasets, which topped FewCLUE and ZeroCLUE benchmark in 2021

## 模型信息 Model Information

基于[Erlangshen-MegatronBert-1.3B](https://huggingface.co/IDEA-CCNL/Erlangshen-MegatronBert-1.3B)，我们在收集的20个中文领域的改写数据集，总计227347个样本上微调了一个Similarity版本。

Based on [Erlangshen-MegatronBert-1.3B] (https://huggingface.co/IDEA-CCNL/Erlangshen-MegatronBert-1.3B), we fine-tuned a similarity version on 8 Chinese paraphrase datasets, with totaling 227,347 samples.

## 使用 Usage

``` python
from transformers import AutoModelForSequenceClassification
from transformers import BertTokenizer
import torch

tokenizer=BertTokenizer.from_pretrained('IDEA-CCNL/Erlangshen-MegatronBert-1.3B-Similarity')
model=AutoModelForSequenceClassification.from_pretrained('IDEA-CCNL/Erlangshen-MegatronBert-1.3B-Similarity')

texta='今天的饭不好吃'
textb='今天心情不好'

output=model(torch.tensor([tokenizer.encode(texta,textb)]))
print(torch.nn.functional.softmax(output.logits,dim=-1))
```
