Ziya-LLaMA-13B 模型在GPU 上部署

Ziya-LLaMA-13B是IDEA-CCNL基于LLaMa的130亿参数的大规模预训练模型,具备翻译,编程,文本分类,信息抽取,摘要,文案生成,常识问答和数学计算等能力。目前姜子牙通用大模型已完成大规模预训练、多任务有监督微调和人类反馈学习三阶段的训练过程。

1. 部署准备

1.1 硬件环境
显卡最低显存为54GB,可以为一张A100(80GB)或者两张A100(40GB)。
6.10日更新增加了模型量化模型,现在的模型只需要一张A100或者两张A10(40GB显卡即可推理)

1.2 python环境

cpm_kernels==1.0.11
gradio==3.34.0
huggingface-hub==0.16.4
Pillow==9.5.0
torch-1.12.1+cu113-cp38-cp38-linux_x86_64.whl    (https://download.pytorch.org/whl/torch/)
tqdm==4.64.1
transformers==4.31.0
accelerate==0.20.3

1.3 模型下载

2 . 模型部署

首先说明一下项目的文件系统目录

-llama-13B
-llama-13B-convert
-ziya_v1.1_delta
-ziya_v1.1
-apply_delta.py
-convert_llama_weights_to_hf.py
-launch.py
-utils.py

其中

  • llama-13B为llama原始参数存放的目录,
  • llama-13B-convert为转换成huggingface形式的参数存放的目录,
  • ziya_v1.1_delta为huggingface上的权重文件,
  • ziya_v1.1为最终转换后的权重文件。
  • launch.py为本地化部署文件,

详见后续章节,utils.py为官方给的文件,直接从https://modelscope.cn/studios/Fengshenbang/Ziya_LLaMA_13B_v1_online/files下载即可。

llama-13B为llama原始参数存放的目录, 原始模型权重不太好下载,可以不用管

llama-13B-convert为转换成huggingface形式的参数存放的目录, 可以直接从网上找转化好的模型权重数据

https://huggingface.co/decapoda-research/llama-13b-hf/tree/main
https://pan.baidu.com/s/1Y7YWdFWX1Yzy2Yuujp8Tqg?pwd=1p5n#list/path=%2FLLaMA(1)%2Fllama-13b

ziya_v1.1_delta为huggingface上的权重文件
https://huggingface.co/IDEA-CCNL/Ziya-LLaMA-13B-v1.1/tree/main

2.1 llama-13B权重转换(如直接下载转化好的模型权重数据,该步骤可省略)

首先第一步需要将llama-13B的原始权重转换成huggingface的权重形式,使用convert_llama_weights_to_hf.py脚本进行转换,转换代码如下:

python convert_llama_weights_to_hf.py --input_dir $你的llama-13B路径 --model_size 13B --output_dir $你的llama-13B模型转换后的路径

2.2 结合基础的llama权重和Ziya-LLaMA-13B delta权重得到Ziya-LLaMA-13B权重

使用如下代码得到最终的Ziya-LLaMA-13B权重。

python -m apply_delta --base $你的llama-13B模型转换后的路径 --target $你的最终权重存储路径 --delta $你下载的Ziya-LLaMA-13B权重路径

2.3 模型部署

使用下面这段代码进行模型部署。该代码修改自https://modelscope.cn/studios/Fengshenbang/Ziya_LLaMA_13B_v1_online/files在官方代码的基础上增加了一些参数和优化内容。

FAQ:

RuntimeError: Failed to import transformers.models.clipseg.modeling_clipseg because of the following error (look up to see its traceback):
