 安装过程复杂曲折，网上说的很多办法，貌似成功了，实际还是没起作用。

先说成功过程，执行下面命令，安装成功（当然，前提是你要先配置好编译环境）：

（我的环境：windows10 、embeded python3.11.9 、pytorch version: 2.5.1+cu124、RTX2080ti）

git clone https://github.com/NVIDIA/apex.gitcd apexcurl -L "https://github.com/NVIDIA/apex/files/14844602/windows_support.patch" | git applypip install -v --disable-pip-version-check --no-cache-dir --no-build-isolation --config-settings "--build-option=--cpp_ext" --config-settings "--build-option=--cuda_ext" .

这个信息，不知道是否说明我的显卡是2系（TORCH_CUDA_ARCH_LIST=7.5）？

成功安装的apex，在卸载apex，你会发现安装的apex含有下面部件： 

---------------下面只是曲折过程，如无必要就不要浪费时间往下看了--------------

1、在comfyUI中，我安装了54个节点，只在安装了节点ComfyUI-PuLID-Flux-Enhanced后，在没有安装apex时，会有如下提示：

于是便想着要安装APEX，看看会不会速度快点，经过了漫长而曲折的过程，终于安装成功，但效果好像没什么变化。

从apex上述介绍中，是否表示，大多时候在Pytorch中已含相关代码？所以，究竟是否值得再花大力气去安装apex呢？还有待进一步探究。

我的环境是python3.11.9 、pytorch version: 2.5.1+cu124

2、首先是报如下错误：

 针对出现的第一个错误：

参考文章《如何设置 TORCH_CUDA_ARCH_LIST 环境变量以优化 PyTorch 性能》，我的显卡是RTX2080Ti，所以设置：

set TORCH_CUDA_ARCH_LIST=7.5

再次编译，错误信息如下：

3、无奈之下，想着试试 torch.__version__  = 2.5.1+cpu时，错误信息提示如下：

4、文章《NVIDIA APEX安装完全指南及Megatron-LM/Pytorch运行问题解决》 

切换到不同的分支：从 GitHub - NVIDIA/apex: A PyTorch Extension: Tools for easy mixed precision and distributed training in Pytorch 的标签页中，可以知道发布的版本，不至于在众多的分支中无所适从。

 切换到分支：24.04.01-devel

不带参数，显示目前所选分支，git clone的初始分支为master：

git checkout 24.04.01-devel

依然报错。

5、参考文章《使用 Visual Studio 2022、CUDA 12.1 和 PyTorch 2.2.2 进行 Windows 编译的最新补丁 #1792》

以下只是想完全照抄原文，使用虚拟环境编译，最终因为我是使用的embeddable python，需要搭建太多东西，放弃，以下只是记录尝试过程中的一些知识。

-------------------------------------------------------------------------------------------------------

文章里的路径，与我的环境并不一样，所以使用dir /x 查看短路径，并且只能一级一级查看：

最终，我的路径如下： 

cmd /c 'C:\PROGRA~2\MICROS~3\2022\BUILDT~1\VC\AUXILI~1\Build\VCVARS~1.BAT amd64 & busybox64u sh -ilX'

将环境中文件复制到windows文件夹，文件夹需要双 \\ ：

建立的虚拟环境，以及git clone 的路径，在“C:\Users\你的用户名” 路径下。

----------------------------------------------------------------------------------------

受文章启发，直接在我的环境中再次安装（执行下面命令生成的whl要比文章头的命令较小，不知道是否因为设置了TORCH_CUDA_ARCH_LIST=7.5只针对我的RTX2080ti）：

git clone https://github.com/NVIDIA/apex.gitcd apexcurl -L "https://github.com/NVIDIA/apex/files/14844602/windows_support.patch" | git applyset DISTUTILS_USE_SDK=1set TORCH_CUDA_ARCH_LIST=7.5pip install -v --disable-pip-version-check --no-cache-dir --no-build-isolation --config-settings "--build-option=--cpp_ext" --config-settings "--build-option=--cuda_ext" .

经过十几分钟，安装成功（如欲将编译成功的whl文件保存下来，需要在编译成功，要进行安装时，按下暂停键Pause，从缓存路径将文件复制，否则，装完后，文件会被删除）。 

成功后，再次启动comfyUI，没有了开始提到的信息。

编译成功后，缓存里面有个文件origin.json，有如下内容，不知道与文章中提到的url有关联？：

{"dir_info": {}, "url": "file:///H:/ComfyUI_cp3.11.9/apex"}
