How to solve issue related to installation of dlib on Windows 10?

问题

I am trying to install dlib for face-recognition for python 3.7 on windows 10, I explored few ways but I am getting errors.I tried below steps-

Installed cmake using 'pip install cmake'. This worked.
Downloaed the Dlib source(.tar.gz) from the Python Package Index : https://pypi.org/project/dlib/#files extract it and enter into the folder.
Ran the installation: python setup.py install

I am getting below error.

Can you please advise how to solve this issue?

In my system i'd done using Anaconda. The Dlib library supports python 3.6 to 3.7.0 in conda environments.

follow the instruction to install face recognition model,

install Anaconda from https://www.anaconda.com/distribution/#download-section
in conda prompt, create an environment using this command

conda create --name env_name python=3.7.0
then activate the env

conda activate env_name
install dlib

conda install -c conda-forge dlib=19.17
