Question

所以基本上我想使用 Python 人脸识别库，为此我必须安装 dlib。我是 Windows 用户，在尝试安装 dlib 时出现此错误

  ERROR: Failed building wheel for dlib

版本详情如下：

C:\Users\Aayush\facedet>pip --version
pip 19.2.3 from C:\Users\Aayush\Anaconda3\lib\site-packages\pip (python 3.7)

我只想以任何可能的方式安装和使用人脸识别库。

Answer 1

尝试使用 face_recognition==0.2.2 版本及其与 dlib==19.3.1 的配合

希望这会有所帮助。
