一、下载源码和模型

下载源码和模型

# 下载源码
git clone https://github.com/ggerganov/llama.cpp.git

# 下载llama-7b模型
git clone https://www.modelscope.cn/skyline2006/llama-7b.git

查看cmake版本：

D:\pyworkspace\llama_cpp\llama.cpp\build>cmake --version
cmake version 3.22.0-rc2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

二、开始build

# 进入llama.cpp目录
mkdir build
cd build
cmake ..

build信息

D:\pyworkspace\llama_cpp\llama.cpp\build>cmake ..

本地使用Realease会出现报错，修改为Debug进行build，这里会使用到visual studio进行build

cmake --build . --config Debug

  ggml.c

在我本地D:\pyworkspace\llama_cpp\llama.cpp\build\bin\Debug目录下面产生了quantize.exe和main.exe等

三、量化和推理

安装相关python依赖

python -m pip install -r requirements.txt

将下载好的llama-7b模型放入models目录下，并执行命令，会在llama-7b目录下面产生ggml-model-f16.gguf文件

python convert.py models/llama-7b/

对产生的文件进行量化

D:\pyworkspace\llama_cpp\llama.cpp\build\bin\Debug\quantize.exe ./models/llama-7b/ggml-model-f16.gguf ./models/llama-7b/ggml-model-q4_0.gguf q4_0

进行推理

D:\pyworkspace\llama_cpp\llama.cpp\build\bin\Debug\main.exe -m ./models/llama-7b/ggml-model-q4_0.gguf -n 256 --repeat_penalty 1.0 --color -i -r "User:" -f prompts/chat-with-bob.txt
