安装支持GPU的dlib时出错

Question

我已经安装了Cmake、visual studio 2019和anaconda。我正在尝试在gpu支持中使用Dlib。但是每次我尝试安装它时，运行python setup.py就会出现以下错误。 我正在使用支持GPU（CUDA）的Dlib

   C:\Users\yugahang\anaconda3\Lib\site-packages\dlib-master>python setup.py install --set 
    USE_AVX_INSTRUCTIONS --set DLIB_USE_CUDA

    running install

    running bdist_egg

    running egg_info

    writing dlib.egg-info\PKG-INFO

    writing dependency_links to dlib.egg-info\dependency_links.txt

    writing top-level names to dlib.egg-info\top_level.txt

    package init file 'dlib\__init__.py' not found (or not a regular file)

    reading manifest file 'dlib.egg-info\SOURCES.txt'


    reading manifest template 'MANIFEST.in'

    no previously-included directories found matching 'tools\python\build*'

    writing manifest file 'dlib.egg-info\SOURCES.txt'

    installing library code to build\bdist.win-amd64\egg

    running install_lib

    running build_py

    running build_ext

    CMake Error: Parse error in command line argument: -DUSE_AVX_INSTRUCTIONS

    Should be: VAR:type=value


    CMake Error: Problem processing arguments. Aborting.

有没有办法解决这个问题。首先，我想知道是什么导致了这个问题

Answer 1

setup.py的参数 set应为

 set <variable>=<value>

这将把cmake参数转换为-D<variable>=<value>，它完全适合于cmake{a1}

例如，代替

 set USE_AVX_INSTRUCTIONS

使用

 set USE_AVX_INSTRUCTIONS=ON

---

setup.py的参数 no没有赋值（=<value>）部分，因为

 no <variable>

自动转换为cmake参数-D<variable>=no
