# Example Python/CNTK for Training Neural Binary Classification Model:
#
#   From CNTK Linux Install Pre-req's: CNTK only fully supported on Ubuntu 16.x
#
#   apt-get install openmpi-bin
#   pip install cntk
#   python -c "import cntk; print(cntk.__version__)"
#
#   Build/Testing Notes:
#
#   Update "Docker Build Interation" on line 28 to force install of new python source
#   Local Unit Test Example: docker run -it -e 'APP_ROOT=/opt/a1day-python-cntk' a1day-python-cntk:latest
#
