## Tiny LLM 92M SFT
|
| 13 |
+
|
| 14 |
+
### 简介
|
| 15 |
+
|
| 16 |
+
本项目[wdndev/tiny-llm-zh (github.com)](https://github.com/wdndev/tiny-llm-zh)旨在构建一个小参数量的中文语言大模型,用于快速入门学习大模型相关知识。
|
| 17 |
+
|
| 18 |
+
模型架构:整体模型架构采用开源通用架构,包括:RMSNorm,RoPE,MHA等
|
| 19 |
+
|
| 20 |
+
实现细节:实现大模型两阶段训练及后续人类对齐,即:预训练(PTM) -> 指令微调(SFT) -> 人类对齐(RLHF, DPO) -> 测评。
|
| 21 |
+
|
| 22 |
+
注意:因资源限制,本项目的第一要务是走通大模型整个流程,而不是调教比较好的效果,故评测结果分数较低,部分生成结构错误。
|
| 23 |
+
|
| 24 |
+
|
| 25 |
+
### 模型细节
|
| 26 |
+
|
| 27 |
+
大约在9B的中文预料中训练,主要包含百科内容,模型架构采用开源通用架构,包括:RMSNorm,RoPE,MHA等。
|
| 28 |
+
|
| 29 |
+
### 环境
|
| 30 |
+
|
| 31 |
+
只需要安装 `transformers` 即可运行
|
| 32 |
+
|
| 33 |
+
### 快速开始
|
| 34 |
+
|
| 35 |
+
```python
|
| 36 |
+
from transformers import AutoTokenizer, AutoModelForCausalLM
|
| 37 |
+
|
| 38 |
+
model_id = "wdndev/tiny_llm_sft_92m"
|
| 39 |
+
|
| 40 |
+
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
|
| 41 |
+
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto", trust_remote_code=True)
|
| 42 |
+
|
| 43 |
+
sys_text = "你是由wdndev开发的个人助手。"
|
| 44 |
+
# user_text = "中国的首都是哪儿?"
|
| 45 |
+
# user_text = "你叫什么名字?"
|
| 46 |
+
user_text = "介绍一下中国"
|
| 47 |
+
input_txt = "\n".join(["<|system|>", sys_text.strip(),
|
| 48 |
+
"<|user|>", user_text.strip(),
|
| 49 |
+
"<|assistant|>"]).strip() + "\n"
|
| 50 |
+
|
| 51 |
+
model_inputs = tokenizer(input_txt, return_tensors="pt").to(model.device)
|
| 52 |
+
generated_ids = model.generate(model_inputs.input_ids, max_new_tokens=200)
|
| 53 |
+
generated_ids = [
|
| 54 |
+
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
|
| 55 |
+
]
|
| 56 |
+
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
|
| 57 |
+
print(response)
|
| 58 |
+
```
