flash_attn安装并未出错，但运行时显示其没有被安装。

[BoosterCore]

在官方的Portable版本中，整个插件安装失败。
然后在秋叶整合版中尝试，插件是装上了，但遇到如题所示问题。

因为作者并没有使用秋叶整合包。在install.bat这个安装脚本中，作者检测了是不是使用comfyui的win protable整合包，如果不是它的那个目录结构，就会默认使用系统的python环境来安装。而秋叶整合包默认使用了SD-Launcher这个python虚拟环境，所以虽然显示安装成功，但实际上秋叶的环境看不到。所以，把install.bat删成这样：

`@echo off

set "requirements_txt=%~dp0\requirements.txt"
set "python_exec=python"

echo Installing ComfyUI's Sound lab Nodes..

REM 调用 python_exec 并获取版本信息
for /f "tokens=*" %%i in ('%python_exec% --version') do set PYTHON_VERSION=%%i

REM 显示 Python 版本
echo %PYTHON_VERSION%

%python_exec% -c "import torch; print(torch.version)"

echo Installing with ComfyUI Portable

@REM %python_exec% -s -m pip install --upgrade --force setuptools==69.5.1

%python_exec% -s -m pip install --upgrade --force ./ffmpy-0.3.2
%python_exec% -s -m pip install --upgrade protobuf==4.25.3

for /f "delims=" %%i in (%requirements_txt%) do (
    %python_exec% -s -m pip install "%%i" -i https://pypi.tuna.tsinghua.edu.cn/simple
）

pause`

就安到秋叶整合包里了。

ps，如果不用audiotools等工具的话， 根据之前issue的回复，将protobuf==4.25.3，不然还是启动会报错。
