checked here a bit and saw a solution actually: https://stackoverflow.com/a/63648302/13692454
But here is new problem, I am using VS code and even if I download C++ extentions, it doesn't fix. I have no idea to what to do. How can i fix this? Thanks in advance*

Just used google colab to fix this problem. Can't find a solution for VS code...

The answer is really simple. You have to do what it says. Go to the VS installer and install VS for C++ and C#. The reason is that these modules use C code and while using Visual Studio, you have to make it so that it can compile the C++ code

For those who don't want to install the entirety of Visual Studio there is an easier way to get the required CMake tools:
Step 1: Download and run Build Tools for Visual Studio 2022 https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2019
Step 2: Go to Individual Components and select C++ CMake tools for Windows and run through the install.
Step 3: Proceed to build your python application (e.g. dlib)

I found the solution, the cause was the version of python that I use version 3.8 but when I changed the version to 3.7 it worked I don't know exactly why I found that onnx did not have 3.8 wheel that's why it is not supported by version 3.8

first you should install dlib for face recognition models. I used the Anaconda to install dlib in created environment,
1. conda install -c conda-forge dlib=19.17
use conda or pip to use install face recognition library.
2. pip install face_recognition
inside of the conda environment. for creating conda environment follow the instruction,
conda create --name env_name python=version
to activate env,
conda activate env_name
to deactivate env
conda deactivate
