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)
FLAGS | MXNet-Scala OSX | MXNet-Scala Linux CPU | MXNet-Scala Linux GPU |
---|---|---|---|
USE_BLAS | |||
USE_LAPACK | 1 | 1 | |
USE_OPENCV | 1 | 1 (opencv 3.4.1) | |
USE_S3 | 1 | 1 | |
USE_DIST_KVSTORE | 0 | 1 | |
USE_SIGNAL_HANDLER | 1 | 1 | |
USE_OPENMP | 1 | 1 | |
USE_CUDNN | 0 | 1 | |
USE_NCCL | 0 | 1 | |

Setup GPG Keys
Build MXNet backend on OSX
- Clone MXNet repo and checkout the release branch
Code Block | ||||
---|---|---|---|---|
| ||||
https://github.com/apache/incubator-mxnet.git ~/$MXNET_LOC git fetch all git checkout -b $RELEASE_BRANCH cp ~/$MXNET_LOC/make/config.mk ~/$MXNET_LOC |
2. Install Lapack
Code Block | ||
---|---|---|
| ||
brew install lapack |
setup all the flags
Code Block |
---|
echo "ADD_CFLAGS += -I/usr/local/opt/lapack/include" >> ~/$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 | ||
---|---|---|
| ||
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=" >> ./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
