# longformer model (Chinese),one model of [Fengshenbang-LM](https://github.com/IDEA-CCNL/Fengshenbang-LM).
We modify the original position code of longformer to rotational position coding,and on the basis of [chinese_roformer_L-12_H-768_A-12.zip](https://github.com/ZhuiyiTechnology/roformer), use 180G of data to continue training
## Usage
There is no structure of Longformer-base in [Transformers](https://github.com/huggingface/transformers), you can run follow code to get structure of longformer from [Fengshenbang-LM](https://github.com/IDEA-CCNL/Fengshenbang-LM)
```shell
git clone https://github.com/IDEA-CCNL/Fengshenbang-LM.git
```
### Load Model
```python
from fengshen import LongformerModel
from fengshen import LongformerConfig
from transformers import BertTokenizer
tokenizer = BertTokenizer.from_pretrained("IDEA-CCNL/longformer_base")
config = LongformerConfig.from_pretrained("IDEA-CCNL/longformer_base")
model = LongformerModel.from_pretrained("IDEA-CCNL/longformer_base")
```
