如何在2020年修复Python/Windows的DLIB

Question

我看到了很多旧的答案，但没有什么新的。我正在尝试pip-install face_recognition，它需要dlib库。我已经尝试过pip安装cmake，它安装得很好。我试图自己pip安装dlib，但出现了错误。我尝试了多个版本，但都不起作用。以下是我试图解决的错误的具体部分。我在YouTube上看了大约10个视频，但没有任何东西能解决这个特定的问题。

CMake Error at C:/Users/Notebook/AppData/Local/Temp/pip-install-m4y9pm9i/dlib/dlib/external/pybind11/tools/FindPythonLibsNew.cmake:124 (message):
Python config failure: Python is 32-bit, chosen compiler is 64-bit

这就是全部错误。

我已经为android编译了dlib，但不需要在windows中为python编译。下载64位Anaconda Python 3.7，创建一个conda environment并在其上安装dlib。

https://anaconda.org/conda-forge/dlib

您可能需要预先安装numpy、opencv等软件包，以避免出现一些错误。然后，您可以在该conda环境中安装pip和face_recognition。

您也可以从那里安装clone the repo。另一种方法是在IDE中打开整个项目，并创建一个python脚本来运行代码。
