【问题描述】：

我正在使用 python 3.7.6 创建一个人脸识别系统。 为此，依赖项是：

opencv-python

cmake

dlib

我已经成功安装opencv-python，cmake

但是在为Python 3.7.6 安装 dlib 库时。我收到一个错误：

但我已经有一个名为 MinGW 的 C++ 编译器，也可以通过终端中的gcc 访问它。

但是如何让 DLIB 使用我的 MinGW 编译器而不是 Visual Studio？

【问题讨论】：

你在使用 anaconda 吗？您可以尝试打开一个新环境并进行全新安装。

对不起，我用的是纯python...

【参考方案1】：

dlib 19.22 在MSYS2 shell 下使用 MinGW-w64 构建得很好。

我使用cmake 进行配置，使用ninja 进行构建。

除了-G"MSYS Makefiles" 之外，不需要特殊的cmake 参数来使用MSYS'make。或者您可以使用-GNinja 来指定ninja 作为构建工具，这样会快很多。

对于发布版本，您还可以添加 -DCMAKE_BUILD_TYPE:STRING=Release。

最后你可以设置-DBUILD_SHARED_LIBS:BOOL=OFF 用于静态构建或-DBUILD_SHARED_LIBS:BOOL=ON 用于共享构建。

简而言之，要使用 MSYS 构建共享 dlib，您可以这样做（将 /path/where/to/install 更改为所需的安装位置）：

cmake.exe -G"MSYS Makefiles" -DCMAKE_INSTALL_PREFIX:PATH=/path/where/to/install -DCMAKE_BUILD_TYPE:STRING=Release -DBUILD_SHARED_LIBS:BOOL=ON -S. -Bbuild_shared
make -Cbuild_shared install/strip

【参考方案2】：

Dlib 需要核心 c++ 依赖项才能编译。我建议你使用 deepface。它更轻巧。

#!pip install deepface
from deepface import DeepFace
obj = DeepFace.verify("img1.jpg", "img2.jpg")
