1 简介
DeepSeek-Coder在多种编程语言和各种基准测试中取得了开源代码模型中最先进的性能。
为尝试在开发板进行部署，首先利用llama.cpp对其进行量化。
2 llama.cpp安装
git clone之后进入文件夹make即可，再将依赖补全pip install -r requirements.txt
3 量化
按照GitHub上DeepSeek和llama.cpp官方的信息，后者对deepseek模型的量化目前的支持（进度）还不是很完善。
下面记录一下目前量化出现的问题。
3.1 DeepSeek官方tutorial
依照官方md
git clone https://github.com/DOGEwbx/llama.cpp.git
cd llama.cpp
git checkout regex_gpt2_preprocess
出现error: pathspec 'regex_gpt2_preprocess' did not match any file(s) known to git
# set up the environment according to README
make
python3 -m pip install -r requirements.txt
# generate GGUF model
python convert-hf-to-gguf.py <MODEL_PATH> --outfile <GGUF_PATH> --model-name deepseekcoder
出现convert-hf-to-gguf.py: error: unrecognized arguments: --model-name deepseekcoder
去掉--model-name参数，出现NotImplementedError: Architecture 'LlamaForCausalLM' not supported!，解释。
3.2 convert.py转换
参考这个comment和这个comment，使用convert.py进行转换。
看起来这个修改已经被合并了，浅浅试一下。
python convert.py <MODEL_PATH> --outfile <GGUF_PATH>
出现错误: Exception: Vocab size mismatch (model has 32256, but ../DeepSeek-Coder/models/deepseek-coder-1.3b-instruct has 32022). Add the --pad-vocab option and try again.
详细的log如下

3.2.1 添加--pad-vocab
首先，显然提示添加参数，根据提示加上--pad-vocab参数后，成功运行并可以成功量化，但是在测试时，会出现以下错误
terminate called after throwing an instance of 'std::out_of_range'what(): _Map_base::at
Aborted (core dumped)
这种情况有相关的issue comment&这个。
从llama.cpp的pull request和issue来看，应该是还没处理好。菜鸡只能嗷嗷待哺了
😥。不知道TheBloke大佬是怎么处理的👍。
（表情网站）
3.2.2 修改vocab_size
其次，根据错误的前半段的model has 32256, but ... has 32022，有类似的issue.
根据comment，对vocal_size进行修改。相应地，打开deepseek-coder-1.3b-instruct中的config.json文件，试将"vocab_size": 32256修改为"vocal_size": 32022。再次运行
python convert.py <MODEL_PATH> --outfile <GGUF_PATH>
输出的log如下
