【问题描述】：

我正在尝试在 Anaconda 中安装 dlib 以便在 jupyter-notebook 中使用它。

我尝试使用conda install -c menpo dlib，然后没有安装 dlib，而是说：

然后，我从here 下载了dlib-19.16.0.tar.gz 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：

  - dlib-19.16.0.tar.gz

【参考方案1】：

第一个错误只是说您无法连接到 menpo 库存储库。我建议检查您的代理/互联网连接。

在第二种情况下，您尝试安装 tar.gz 文件，这是一个压缩文件。先解压（解压）再安装。

【讨论】：

conda install -c conda-forge dlib-19.16.0 在解压 tar 文件后说同样的话。

下载***，.whl 文件，然后尝试以这种方式安装它。确保您的 Python 版本和操作系统是正确的，因为该***适用于 Python 3.6 和 Windows 64 位。顺便说一句，tar 文件仍然是一个压缩文件。因此，如果您解压缩它，您将能够看到 setup.py 文件和 dlib 库的所有其他组件。使用 setup.py 您将能够安装该库，但为了做到这一点，您需要一个 cpp 编译器等，所以我建议您使用该链接中提供的***安装它。
