dlib: dlib 19.20 python setup.py install/build failed

Expected Behavior

I was trying to build dlib through: python setup.py install but it failed after 2% build

Current Behavior

Terminal output below: $ python setup.py install running build running build_py package init file ‘dlib/init.py’ not found (or not a regular file) running build_ext Building extension for Python 3.5.2 (default, Nov 23 2017, 16:37:01) Invoking CMake setup: ‘cmake /home/surveillance6/Downloads/dlib-19.20/tools/python -DCMAKE_LIBRARY_OUTPUT_DIRECTORY=/home/surveillance6/Downloads/dlib-19.20/build/lib.linux-x86_64-3.5 -DPYTHON_EXECUTABLE=/home/surveillance6/virt_envs/mlenv/bin/python -DCMAKE_BUILD_TYPE=Release’ – The C compiler identification is GNU 5.4.0 – The CXX compiler identification is GNU 5.4.0 – Check for working C compiler: /usr/bin/cc – Check for working C compiler: /usr/bin/cc – works – Detecting C compiler ABI info – Detecting C compiler ABI info - done – Detecting C compile features – Detecting C compile features - done – Check for working CXX compiler: /usr/bin/c++ – Check for working CXX compiler: /usr/bin/c++ – works – Detecting CXX compiler ABI info – Detecting CXX compiler ABI info - done – Detecting CXX compile features – Detecting CXX compile features - done – Found PythonInterp: /home/surveillance6/virt_envs/mlenv/bin/python (found version “3.5.2”) – Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.5m.so – Performing Test HAS_CPP14_FLAG – Performing Test HAS_CPP14_FLAG - Success – pybind11 v2.2.2 – Using CMake version: 3.5.1 – Compiling dlib version: 19.20.0 – SSE4 instructions can be executed by the host processor. – AVX instructions can be executed by the host processor. – Enabling AVX instructions – Looking for pthread.h – Looking for pthread.h - found – Looking for pthread_create – Looking for pthread_create - not found – Looking for pthread_create in pthreads – Looking for pthread_create in pthreads - not found – Looking for pthread_create in pthread – Looking for pthread_create in pthread - found – Found Threads: TRUE

Steps to Reproduce

I am using: Ubuntu 16.04, cuda 10.1 cudnn also seems to be installed. was doing python setup.py build inside virtual environment I am able to successfully build dlib 19.19 in same environment.
