在没有GPU支持的MacOS上安装cupy

Question

我一直在论坛上尝试在没有Nvidia GPU的设备上运行MacOS上安装cupy的不同方法。到目前为止，一切都没有奏效。我尝试了Homebrew安装的Python 3.7和conda安装的Python 3.7，并尝试了以下每一个:

• conda install -c conda-forge cupy
• conda install cupy
• pip install cupy

• git clone https://github.com/cupy/cupy.git
  cd cupy
  git submodule update --init
  pip install -e .
  

错误总是在同一脉…对于conda, MacOS repos没有它，对于pip，安装抱怨CUDA没有安装在我的系统上。从我在网上读到的东西来看，cupy应该能够安装为仅用于开发目的的cpu，我希望有人能给我一些启发，我可能能够做些什么来获得一个工作安装。

以下是pip install cupy参考的错误日志示例:

Answer 1

由于NVIDIA不再支持MacOS，所以CuPy中没有Mac支持。你读的东西都过时了。我知道这一点，因为我发送了一个PR来删除CuPy代码库中最后的破碎部分，并且我还在conda-forge上维护CuPy包。
