WARNING: You are using pip version 19.1, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
Cmake and boost need to be installed before Dlib is installed. Then Dlib can be installed correctly
pip install boost
pip install cmake
pip install dib
