From the Hugging Face model README
发布中文LLaMA, Alpaca Plus版(7B)模型
推出中文LLaMA, Alpaca Plus版(7B),相比基础版本的改进点如下:
本模型是原生LLaMA-7B合并中文LLaMA LoRA和中文Alpaca LoRA后的模型权重chinese-alpaca-plus-7b-hf,并转化为HuggingFace版本权重(.bin文件),可以直接使用或者继续训练。
13b-hf权重链接:https://huggingface.co/shibing624/chinese-alpaca-plus-13b-hf
test case:
| input_text | predict |
|---|---|
| 为什么天空是蓝色的? | 天空是蓝色的,是因为大气层中的气体分子会散射太阳光中的蓝色光,使得我们看到的天空是蓝色的。 |
本项目开源在textgen项目:textgen,可支持llama模型,通过如下命令调用:
Install package:
pip install -U textgen
from textgen import GptModel
model = GptModel("llama", "shibing624/chinese-alpaca-plus-7b-hf")
r = model.predict(["用一句话描述地球为什么是独一无二的。"])
print(r) # ['地球是独一无二的,因为它拥有独特的大气层、水循环、生物多样性以及其他自然资源,这些都使它成为一个独特的生命支持系统。']
Without textgen, you can use the model like this:
First, you pass your input through the transformer model, then you get the generated sentence.
Install package:
pip install sentencepiece
pip install transformers>=4.28.0
import torch
import transformers
from transformers import LlamaTokenizer, LlamaForCausalLM
def generate_prompt(text):
return f"""Below is an instruction that describes a task. Write a response that appropriately completes the request.
### Instruction:
{text}
### Response:"""
tokenizer = LlamaTokenizer.from_pretrained('shibing624/chinese-alpaca-plus-7b-hf')
model = LlamaForCausalLM.from_pretrained('shibing624/chinese-alpaca-plus-7b-hf').half().cuda()
model.eval()
text = '为什么天空是蓝色的?'
prompt = generate_prompt(text)
input_ids = tokenizer.encode(prompt, return_tensors='pt').to('cuda')
with torch.no_grad():
output_ids = model.generate(
input_ids=input_ids,
max_new_tokens=128,
temperature=1,
top_k=40,
top_p=0.9,
repetition_penalty=1.15
).cuda()
output = tokenizer.decode(output_ids[0], skip_special_tokens=True)
print(output.replace(text, '').strip())
output:
为什么天空是蓝色的?
天空是蓝色的,是因为大气层中的气体分子会散射太阳光中的蓝色光,使得我们看到的天空是蓝色的。
release合并后的模型权重,一步到位直接使用,省电、减少碳排放。
基于 多LoRA权重合并(适用于Chinese-Alpaca-Plus )方法手动合并而成,具体是使用 decapoda-research/llama-7b-hf 底座模型 合并 Chinese-LLaMA-Plus-LoRA和Chinese-Alpaca-Plus-LoRA 两个LoRA权重 得到,并转化为HuggingFace版本权重(.bin文件)。
HuggingFace版本权重(.bin文件)可用于:
PyTorch版本权重(.pth文件)可用于:
