ELYZA-japanese-Llama-2-7b

模型描述

ELYZA-japanese-Llama-2-7b 是基于Llama2架构，通过追加预训练扩展日语能力的语言模型。详情请参阅技术博客。

使用示例

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

B_INST, E_INST = "[INST]", "[/INST]"
B_SYS, E_SYS = "<<SYS>>\n", "\n<</SYS>>\n\n"
DEFAULT_SYSTEM_PROMPT = "あなたは誠実で優秀な日本人のアシスタントです。"
text = "クマが海辺に行ってアザラシと友達になり、最終的には家に帰るというプロットの短編小説を書いてください。"

model_name = "elyza/ELYZA-japanese-Llama-2-7b-instruct"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype="auto")

if torch.cuda.is_available():
    model = model.to("cuda")

prompt = "{bos_token}{b_inst} {system}{prompt} {e_inst} ".format(
    bos_token=tokenizer.bos_token,
    b_inst=B_INST,
    system=f"{B_SYS}{DEFAULT_SYSTEM_PROMPT}{E_SYS}",
    prompt=text,
    e_inst=E_INST,
)


with torch.no_grad():
    token_ids = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt")

    output_ids = model.generate(
        token_ids.to(model.device),
        max_new_tokens=256,
        pad_token_id=tokenizer.pad_token_id,
        eos_token_id=tokenizer.eos_token_id,
    )
output = tokenizer.decode(output_ids.tolist()[0][token_ids.size(1) :], skip_special_tokens=True)
print(output)
"""
遵命。下面为您创作关于熊去海边与海豹成为朋友，最终回家的短篇小说：

熊正在山林里酣睡。
沉睡中的熊梦见自己漫步在海滩。
一只海豹出现在眼前。
熊主动向海豹搭话。

"早上好"熊说道，海豹惊讶地抬起头。
"啊，你好"海豹回应道。
熊想与海豹成为朋友。

"我是熊先生。"熊继续...
