## 简介 Brief Introduction

基于悟道数据集预训练，善于处理NLG任务，目前最大的，中文版的GPT2。

Pretraining on Wudao Corpus, focused on handling NLG tasks, the current largest, Chinese GPT2.

## 模型信息 Model Information

为了可以获得一个强大的单向语言模型，我们采用GPT模型结构，并且应用于中文语料上。类似于Wenzhong-GPT2-3.5B，这个模型拥有30层解码器和35亿参数，这比原本的GPT2-XL还要大。不同的是，我们把这个模型在悟道（300G版本）语料上进行预训练。据我们所知，它是目前最大的中文的GPT模型。

To obtain a powerful unidirectional language model, we adopt the GPT model structure and apply it to the Chinese corpus. Similar to Wenzhong-GPT2-3.5B, this model has 30 decoder layers and 3.5 billion parameters, which is larger than the original GPT2-XL. The difference is that we pre-trained this model on the Wudao (300G version) corpus. To the best of our knowledge, it is the largest Chinese GPT model currently available.

## 使用 Usage

### 加载模型 Loading Models

```python 
from transformers import GPT2Tokenizer, GPT2LMHeadModel
tokenizer = GPT2Tokenizer.from_pretrained('IDEA-CCNL/Wenzhong2.0-GPT2-3.5B-chinese')
model = GPT2LMHeadModel.from_pretrained('IDEA-CCNL/Wenzhong2.0-GPT2-3.5B-chinese')
text = "Replace me by any text you'd like."
encoded_input = tokenizer(text, return_tensors='pt')
output = model(**encoded_input)
```

### 使用示例 Usage Examples

```python
from transformers import pipeline, set_seed
set_seed(55)
generator = pipeline('text-generation', model='IDEA-CCNL/Wenzhong2.0-GPT2-3.5B-chinese')
generator("北京位于", max_length=30, num_return_sequences=1)
