this is my step-by-step solution

    apt-get update
    apt-get install build-essential cmake
    apt-get install libopenblas-dev liblapack-dev 
    apt-get install libx11-dev libgtk-3-dev
    apt-get install python python-dev python-pip
    apt-get install python3 python3-dev python3-pip

then install dlib

    cd ~
    mkdir temp
    cd temp
    git clone https://github.com/davisking/dlib.git
    cd dlib
    mkdir build; cd build; cmake ..; cmake --build .
    cd ..
    python3 setup.py install

then install face_recognition

    pip3 install numpy scipy matplotlib pandas face_recognition

Although I don't know the cause of the loop, I found a workaround by creating a (Anaconda) container with python version 3.6.9 (whereas at first I tried to install face_recognition with python version 3.7.3. Hope it helps.
