## 简介 Brief Introduction

善于处理长文本，采用旋转位置编码的中文版3.3亿参数的Longformer-large

The Chinese Longformer-large (330M), which uses rotating positional encoding, is adept at handling lengthy text.

## 模型信息 Model Information

遵循Longformer-large的设计，我们基于[chinese_roformer_L-12_H-768_A-12](https://github.com/ZhuiyiTechnology/roformer)，在悟道语料库(180 GB版本)上进行了继续预训练。特别的，我们采用旋转位置嵌入(RoPE)来避免预训练语料库的不均匀序列长度问题。

Following the design of Longformer-large, we performed continual pre-training on the WuDao corpus (180 GB) based on [chinese_roformer_L-12_H-768_A-12](https://github.com/ZhuiyiTechnology/roformer). Particularly, we employed rotational position embedding (RoPE) to avoid the uneven sequence length of the pre-trained corpus.

## 使用 Usage

因为[transformers](https://github.com/huggingface/transformers)库中是没有Longformer-large相关的模型结构的，所以你可以在我们的[Fengshenbang-LM](https://github.com/IDEA-CCNL/Fengshenbang-LM)中找到并且运行代码。

Since there is no structure of Longformer-large in [transformers library](https://github.com/huggingface/transformers), you can find the structure of Longformer-base and run the codes in [Fengshenbang-LM](https://github.com/IDEA-CCNL/Fengshenbang-LM).

 ```shell
 git clone https://github.com/IDEA-CCNL/Fengshenbang-LM.git
 ```

### 加载模型 Loading Models

```python
