这个错误提示是因为你需要先安装CMake来构建dlib。你可以使用以下命令来安装CMake：

sudo apt-get install cmake

或者使用以下命令安装dlib：

pip install dlib --install-option="--no DLIB_USE_CUDA"

这个命令会安装dlib但不包括CUDA支持。

3. 为 python 安装 pandas 库，且采用镜像网站：https://pypi.tuna.tsinghua.edu.cn/simple，则在 cmd 窗口输入（ ）。 （A）pip install pandas https://pypi.tuna.tsinghua.edu.cn/simple （B）pip install pandas -h https://pypi.tuna.tsinghua.edu.cn/simple （C）pip install pandas -i https://pypi.tuna.tsinghua.edu.cn/simple （D）pip install pandas -k https://pypi.tuna.tsinghua.edu.cn/simple答案是什么为什么

答案是：（C）pip install pandas -i https://pypi.tuna.tsinghua.edu.cn/simple。

这是因为选项（C）中的 `-i` 参数可以指定库的安装源为指定的镜像网站。在这个情况下，`https://pypi.tuna.tsinghua.edu.cn/simple` 是指定的镜像网站，通过使用 `-i` 参数，可以将安装源设置为该镜像网站。

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn numpy

As an AI language model, I do not have the capability to install packages or execute commands on a local machine. However, the following command will install numpy using pip with Tsinghua University mirror:

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn numpy

This command will use the Tsinghua University mirror as the source for the package and the `--trusted-host` option is used to avoid SSL warnings.
