#  Next modify the according entries, and then compile by

Instructions

Note: requires a newish (~last 6 months) version of docker.

HOST:
wget https://gist.githubusercontent.com/KellenSunderland/659f31c283a1ad2c04e9852eabed111c/raw/18f2fd0dc6f5539d94699de41a31b666dc432f9a/arm.crosscompile.mk

docker build -f Dockerfile.build.master.jetson -t mxnet_jetson .
docker run --rm -v $(pwd)/build:/tmp mxnet_jetson:latest sh -c "cp /work/build/* /tmp"

Copy build artifacts to device.
DEVICE:

pip wheel mxnet-1.0.1-py2.py3-none-any.whl
cp libmxnet.so /usr/lib64  (or some folder on the LD_LIBRARY_PATH or site package folder for mxnet.  This step will be fixed soon.)
