Qra-1b-dolly-instruction-0.1

该模型是基于OPI-PG/Qra-1b在s3nh/alpaca-dolly-instruction-only-polish数据集上微调的版本。

模型描述

基于OPI-PG/Qra-1b训练

用途与限制

该模型针对问答任务进行了微调。虽然可以用于聊天，但由于数据集中不包含对话内容，效果可能不佳。

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline

model_id = "nie3e/Qra-1b-dolly-instruction-0.1"
device = "cuda" if torch.cuda.is_available() else "cpu"

model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
)
tokenizer = AutoTokenizer.from_pretrained(model_id)
pipe = pipeline(
    "text-generation", model=model, tokenizer=tokenizer, device=device
)

def get_answer(system_prompt: str, user_prompt: str) -> str:
    input_msg = [
        {"role": "system", "content": system_prompt},
        {"role": "user", "content": user_prompt}
    ]
    prompt = pipe.tokenizer.apply_chat_template(
        input_msg, tokenize=False,
        add_generation_prompt=True
    )
    outputs = pipe(
        prompt, max_new_tokens=512, do_sample=False, temperature=0.1, top_k=50,
        top_p=0.1, eos_token_id=pipe.tokenizer.eos_token_id,
        pad_token_id=pipe.tokenizer.pad_token_id
    )
    return outputs[0]['generated_text'][len(prompt):].strip()

print(
        get_answer(
        system_prompt="你是一个友好的聊天机器人",
        user_prompt="请解释什么是架构决策记录文档"
    )
)

训练与评估数据

数据集: s3nh/alpaca-dolly-instruction-only-polish

每条数据通过以下函数转换为对话格式:

system_message = """你是一个友好的聊天机器人"""

def create_conversation(sample) -> dict:
    strip_characters = "\"'"
    return {
        "messages": [
            {"role": "system", "content": system_message},
            {"role": "user",
             "content": f"{sample['instruction'].strip(strip_characters)} "
                        f"{sample['input'].strip(strip_characters)}"},
            {"role": "assistant",
             "content": f"{sample['output'].strip(strip_characters)}"}
        ]
    }
