# This script shows how one can build a Caffe2 binary for NVidia's TX1.
# The build script assumes that you have the most recent libraries installed
# via the JetPack toolkit available at
#     https://developer.nvidia.com/embedded/jetpack
# and it assumes that we are starting from a fresh system after the jetpack
# installation. If you have already installed some of the dependencies, you
# may be able to skip quite a few of the apt-get installs.
