Publishing Scala Packages to Nexus/Maven

Currently 3 Packages from the above generated are published to Maven. `mxnet_full_2.11-{platform}`.

The following flags are used to build the MXNet Backend(derived from mxnet pip compiler flags)

...

MXNet-Scala Linux CPU

...

USE_CUDNN

...

Build MXNet backend on OSX

  1. Clone MXNet repo and checkout the release branch
Code Block
languagebash
collapsetrue
https://github.com/apache/incubator-mxnet.git ~/$MXNET_LOC
git fetch all
git checkout -b $RELEASE_BRANCH
cp ~/$MXNET_LOC/make/config.mk ~/$MXNET_LOC

2. Install Lapack

Code Block
languagebash
brew install lapack

setup all the flags

Code Block
echo "ADD_CFLAGS  += -I/usr/local/opt/lapack/include" >> ~/$MXNET_LOC/config.mk
echo "ADD_LDFLAGS += -L/usr/local/opt/lapack/lib"     >> ~/$MXNET_LOC/config.mk
echo "USE_OPENMP = 0" >> ~/$MXNET_LOC/config.mk

Build MXNet backend on Linux-CPU

To build for linux-cpu platform, we use the AWS Deep Learning Base AMI that comes built with all the necessary 

libraries such as opencv/cudnn etc,.

Install Maven on Ubuntu

Code Block
languagebash
sudo apt-get install -y maven

setup all the flags

Code Block
echo "ADD_CFLAGS += -I/usr/local/include/opencv" >> ./config.mk
echo "ADD_LDFLAGS += -L/usr/local/lib" >> ./config.mk
echo "USE_BLAS=openblas" >> ./config.mk 
echo "USE_SIGNAL_HANDLER=1" >> ./config.mk
echo "USE_DIST_KVSTORE=1" >> ./config.mk
echo "USE_S3=1" >> ./config.mk
echo "USE_OPENMP=1" >> ./config.mk

Note: compiling with OpenBlas throws a segmentation fault on both OSX and Linux platforms

Publishing to Maven

Code Block
languagebash
export GPG_TTY=$(tty)
make scalapkg
make scalarelease-dryrun

...
