在 M2 Ultra 上使用 Metal 安装 llama-cpp-python 失败

Question

我按照 https://llama-cpp-python.readthedocs.io/en/latest/install/macos/ 上的说明进行操作。

我的macOS版本是Sonoma 14.4，并且已经安装了xcode-select（版本：15.3.0.0.1.1708646388）。

我用
创建了一个 conda 环境 “康达版本：24.1.2”
“Python版本：3.10.13.final.0”
“平台：osx-arm64”。

我运行以下命令来安装 llama-cpp-python

CMAKE_ARGS="-DLLAMA_METAL=on" pip install -U llama-cpp-python --no-cache-dir

，但最终出现以下错误消息。

我尝试了以下命令

export CMAKE_ARGS="-DLLAMA_METAL=on" 
export FORCE_CMAKE=1 
pip install llama-cpp-python --no-cache-dir   

，但我刚刚收到同样的错误消息。

我还尝试了链接（3.9.16）中的较旧的Python版本，但它也不起作用。

有人可以帮我解决这个问题吗？提前非常感谢。

首先，我要感谢 Spo1ler 的发现。

我只安装了 xcode-select 而不是 Xcode.app，它的路径是

/Library/Developer/CommandLineTools

基于https://github.com/gfx-rs/gfx/issues/2309#issuecomment-506130902， 我从 Apple App Store 安装了 Xcode.app。 然后，我可以看到xcode-select的路径自动更改为

/Applications/Xcode.app/Contents/Developer

然后，我必须先运行 Xcode.app 以同意 Xcode 许可协议。之后，以下命令将起作用。

export CMAKE_ARGS="-DLLAMA_METAL=on" 
export FORCE_CMAKE=1 
pip install llama-cpp-python --no-cache-dir
