苹果AppleMacOs系统Sonoma本地部署无内容审查(NSFW)大语言量化模型Causallm
最近Mac系统在运行大语言模型（LLMs）方面的性能已经得到了显著提升，尤其是随着苹果M系列芯片的不断迭代，本次我们在最新的MacOs系统Sonoma中本地部署无内容审查大语言量化模型Causallm。
这里推荐使用koboldcpp项目，它是由c++编写的kobold项目，而MacOS又是典型的Unix操作系统，自带clang编译器，也就是说MacOS操作系统是可以直接编译C语言的。
首先克隆koboldcpp项目：
git clone https://github.com/LostRuins/koboldcpp.git 随后进入项目：
cd koboldcpp-1.60.1 输入make命令，开始编译：
make LLAMA_METAL=1
这里的LLAMA_METAL=1参数必须要添加，因为要确保编译时使用M系列芯片，否则推理速度会非常的慢。
程序返回：
(base) ➜ koboldcpp-1.60.1 make LLAMA_METAL=1

Your OS does not appear to be Windows. For faster speeds, install and link a BLAS library. Set LLAMA_OPENBLAS=1 to compile with OpenBLAS support or LLAMA_CLBLAST=1 to compile with ClBlast support. This is just a reminder, not an error.
说明编译成功，但是最后会有一句提示：

接着通过conda命令来创建虚拟环境：
conda create -n kobold python=3.10 接着激活环境，并且安装依赖：
(base) ➜ koboldcpp-1.60.1 conda activate kobold
(kobold) ➜ koboldcpp-1.60.1 pip install -r requirements.txt最后启动项目：
Python3 koboldcpp.py --model /Users/liuyue/Downloads/causallm_7b-dpo-alpha.Q5_K_M.gguf --gpulayers 40 --highpriority --threads 300这里解释一下参数：
gpulayers - 允许我们在运行模型时利用 GPU 来获取计算资源。我在终端中看到最大层数是 41，但我可能是错的。
threads - 多线程可以提高推理效率
highpriority - 将应用程序在任务管理器中设置为高优先级，使我们能够将更多的计算机资源转移到kobold应用程序 程序返回：

Metal加速在Mac上利用Metal Performance Shaders (MPS)后端来加速GPU推理。MPS框架通过针对每个Metal GPU系列的独特特性进行微调的内核，优化计算性能。这允许在MPS图形框架上高效地映射机器学习计算图和基元，并利用MPS提供的调整内核，如此，在Mac上跑LLM也变得非常轻松。
