Llama-2-7b-vicuna-Chinese
Llama-2-7b-vicuna-Chinese是在中英双语sharegpt数据上全参数微调的对话模型。
- 基座模型:meta-llama/Llama-2-7b-hf 允许商业使用。
- 微调数据:ShareGPT,ShareGPT-ZH,Langchain-MRKL-finetune
- 训练代码:基于FastChat
Llama-2-7b-vicuna-Chinese is a chat model supervised finetuned on vicuna sharegpt data in both English and Chinese.
- Foundation model: meta-llama/Llama-2-7b-hf, a commercially available language model.
- Finetuning data: ShareGPT,ShareGPT-ZH,Langchain-MRKL-finetune
- Training code: based on FastChat
主要改进:中英能力相比Llama2原版和vicuna均有提升
- 英语能力基础评测(MMLU): Llama-2-7b-vicuna-Chinese(48.8) > Llama-2-7b(45.3) > vicuna1.1(44.8)
- 中文能力基础评测(C-Eval): Llama-2-7b-vicuna-Chinese(34.7) > Llama-2-7b-chat(30.3)= vicuna1.1(30.3)
- 实测效果:不会出现Llama2-chat的过于谨慎的状况
- English Eval results(MMLU): Llama-2-7b-vicuna-Chinese(48.8) > Llama-2-7b(45.3) > vicuna1.1(44.8)
- Chinese Eval results(C-Eval): Llama-2-7b-vicuna-Chinese(34.7) > Llama-2-7b-chat(30.3)= vicuna1.1(30.3)
- Empirical Results: It will not be overly cautious like Llama2-chat.
Loading the Weights with Hugging Face Transformers
See the following example for usage.
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("PengQu/Llama-2-7b-vicuna-Chinese",use_fast=False)
model = AutoModelForCausalLM.from_pretrained("PengQu/Llama-2-7b-vicuna-Chinese").to("cuda")
instruction = "A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. USER: {} ASSISTANT:"
prompt = instruction.format('用flask写一个简单的http服务器。')
input_ids = tokenizer(prompt, return_tensors="pt").input_ids.to("cuda")
generation_output = model.generate(input_ids=input_ids, max_new_tokens=512)
print(tokenizer.decode(generation_output[0],skip_special_tokens=True))
输出如下(output as follows):
要使 用Flask创建一个简单的HTTP服务器,您需要在终端中运行以下命令:
pip install Flask
这将安装Flask包并准备您使用它。
以下是一个简单的Flask应用程序,它侦听端口5000并响应“Hello, World!”消息:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return 'Hello, World!'
if __name__ == '__main__':
app.run(debug=True)
要运行此应用程序,您可以将代码保存到名为`app.py`的文件中,然后在终端中运行以下命令:
python app.py
这将启动Flask服务器,并且您应该能够通过在Web浏览器中访问`http://localhost:5000`来访问“Hello, World!”消息。
您还可以使用Flask的路由功能为不同的URL定义不同的端点。例如,您可以定义一个路由,在端口8080上侦听,并响应“Hello, Flask!”消息:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return 'Hello, Flask!'
if __name__ == '__main__':
app.run(debug=True, host='localhost', port=8080)
要运行此应用程序,您可以将代码保存到名为`app.py`的文件中,然后在终端中运行以下命令:
python app.py
