Testing Scala Release Jars from Clojure Package

The Clojure package depends on the Scala package jars. During the release process, new Scala jars are pushed to the staging repository for testing. This guide covers the manual steps that are taken to verify that they work.

There are currently 3 architectures supported, OSX cpu, LInux cpu, and Linux gpu. You will need to perform the following actions on each architecture.

Load any OS/Architecture dependencies (see MXNet-Scala Release Process for build details per architecture)
- For Ubuntu you will need
- For Deep Learning AMI Ubuntu p2.xlarge you will need only Leningen
  - ```
  wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
  chmod 755 lein 
  mv lein /usr/local/bin/.
```
git clone https://github.com/apache/incubator-mxnet.git
- note do not need recursive
```
 cd incubator-mxnet
```
Find tag with
git clone https://github.com/apache/incubator-mxnet.git

git checkout tags/<tag_name> -b <branch_name>

cd contrib/clojure
vi project.clj
- Edit the scala mxnet dependency for the correct version and architecture. Ex:
  [org.apache.mxnet/mxnet-full_2.11-linux-x86_64-gpu "1.3.0”]
lein test
- This will download the scala jar from staging and run the clojure test suite. There should be no errors.
lein install
- This will create the Clojure jar and install it in the local maven repo
cd examples/imclassification
- Run the example for the correct build
- ```
lein run :cpu
```
  - will run on 1 cpu
- ```
lein run :cpu 2
```
  - will run on 2 cpus
- ```
lein run :gpu 
```
  - will run on 1 gpu
- ```
lein run :gpu 2
```
  - will run on 2 gpus
