无法在anaconda中安装dlib

Question

我试图在Anaconda中安装dlib，以便在jupyter-笔记本中使用它。

我尝试使用conda install -c menpo dlib，然后dlib没有安装，而是这样说：

然后，我从这里下载了这里，并将其保存在/anaconda3/lib/python3.6/site-packages中，然后运行conda install -c conda-forge dlib-19.16.0.tar.gz，但它显示：

PackagesNotFoundError: The following packages are not available from current channels:

  - dlib-19.16.0.tar.gz

第一个错误仅仅是说您无法连接到menpo库库。我建议检查您的代理/互联网连接。

在第二种情况下，您试图安装一个tar.gz文件，这是一个压缩文件。首先解压缩它(解压缩)，然后尝试安装它。
