Issue was due to library path was empty, i manually updated setup.py
#python_library = os.path.join(sysconfig.get_config_var(var), 'libpython{}.{}'.format(sysconfig.get_python_version(), dynamic_library_extension))
to
python_library = os.path.join("C:\Users\XXX\Anaconda3\envs\tensorflow\libs", 'libpython{}.{}'.format(sysconfig.get_python_version(), dynamic_library_extension)
..
Adding hard coded value is not solution I will left it to developer if they want to close it.
