【问题描述】：

我尝试了在 anaconda 和 python 中安装 dlib 的所有方法，但每次尝试导入它时都会收到以下响应：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\malle\AppData\Local\Programs\Python\Python36\dlib.py", line 7, in <module>
    x = dlib.vectors()
AttributeError: module 'dlib' has no attribute 'vectors'

你能帮帮我吗？我使用 python 3.6.8

【问题讨论】：

我们需要有关您如何尝试安装的更多信息。您需要有一个 c/c++ 编译器才能正确安装，这在大多数 python 库中有点独特。大多数库都提供预编译的二进制文件。在 Windows 上，您可以通过 Visual Studio 获取编译器和开发工具链

是的，我尝试使用 pip install cmake 也使用 conda install -c conda-forge dlib 和所有方法，但没有任何效果！

您是否安装并工作了cmake 和msvc 编译器（或其他一些c/c++ 编译器）？调用 setup.py 时可能会收到错误消息

cmake 不是来自 pip。获取 cmake 的最简单方法是从 Visual Studio 安装程序

尝试在 Windows 命令提示符（或 powershell）中键入 cmake -h。您是否收到一大段描述该工具如何工作的文本，或者找不到该命令？
