## 简介 Brief Introduction

2021年登顶FewCLUE和ZeroCLUE的中文BERT，在数个推理任务微调后的版本

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

## 模型分类 Model Taxonomy

|  需求 Demand  | 任务 Task       | 系列 Series      | 模型 Model    | 参数 Parameter | 额外 Extra |

| 通用 General  | 自然语言理解 NLU | 二郎神 Erlangshen | MegatronBert |      1.3B      |     NLI     |

## 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4个用于finetune的中文领域的NLI（自然语言推理）数据集，总计1014787个样本上微调了一个NLI版本。

Based on [Erlangshen-MegatronBert-1.3B](https://huggingface.co/IDEA-CCNL/Erlangshen-MegatronBert-1.3B), we fine-tuned an NLI version on 4 Natural Language Inference (NLI) datasets that are commonly used for fine-tuning in Chinese field, with totaling 1,014,787 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-NLI')
model=AutoModelForSequenceClassification.from_pretrained('IDEA-CCNL/Erlangshen-MegatronBert-1.3B-NLI')
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))
```
