Create a Maven Project For JAVA and Scala

Scala

mvn archetype-generate

And type in the number for the highlighted one as shown below. We are looking for the archetype org.scala-tools.archetypes:scala-archetype-simple

The following prompts will ask you for the group-id and artifact-id and may be some other things, but when you are done, maven will create a sample pom.xml file and directory structure with src/main/scala, src/test/scala.

That's it. Now you can start coding in Scala and compile and build your code using Maven.

JAVA

mvn archetype-generate

And type in the number for the highlighted one as shown below. We are looking for the archetype org.apache.maven.archetypes:maven-archetype-quickstart

The following prompts will ask you for the group-id and artifact-id and may be some other things, but when you are done, maven will create a sample pom.xml file and directory structure with src/main/java, src/test/java.

That's it. Now you can start coding in JAVA and compile and build your code using Maven.

Running Tensorflow in a Docker Container in Ubuntu

I found that the easiest and hassle-free way of running the GPU version of Tensorflow is with the help of docker as you don't have to worry about the CUDA versions and Tensorflow versions compatibility. This is a tutorial to use Tensorflow in a docker container in Ubuntu. If you were to use Tensorflow in a docker container in Mac or Windows, it will only be simpler than this tutorial because you just need to install Docker for Desktop application for Mac or Windows as opposed to a Docker Engine.

Install Docker CE in Ubuntu

Uninstall old versions

sudo apt-get remove docker docker-engine docker.io containerd runc

Set up the repository

sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

Add Docker’s official GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Verify the fingerprint

sudo apt-key fingerprint 0EBFCD88

Add the repository

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

Verify the Docker CE installation

sudo docker run hello-world

Install nvidia-docker2 for GPU support (Only necessary if you're planning on running Tensorflow in GPU)

If you have nvidia-docker 1.0 installed: we need to remove it and all existing GPU containers docker volume 

ls -q -f driver=nvidia-docker | xargs -r -I{} -n1 docker ps -q -a -f volume={} | xargs -r docker rm -f sudo apt-get purge -y nvidia-docker

Add the package repositories 

curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey|sudo apt-key add - 

distribution=$(. /etc/os-release;echo $ID$VERSION_ID) 

curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

sudo apt-get update

Install nvidia-docker2 and reload the Docker daemon configuration

sudo apt-get install -y nvidia-docker2 

sudo pkill -SIGHUP dockerd

Test nvidia-smi with the latest official CUDA image 

docker run --runtime=nvidia --rm nvidia/cuda:9.0-base nvidia-smi

Get Tensorflow docker image from docker hub 

# run one of the following commands based on your need. Tag variants are
-gpu, -py3 and -jupyter

sudo docker pull tensorflow/tensorflow:latest-gpu-py3 #pulls the latest tensorflow docker image with GPU support and python3

sudo docker pull tensorflow/tensorflow:latest #pulls the latest tensorflow docker image with CPU only support and python2

Instantiate your container from your tensorflow docker image

# for tensorflow CPU image with python 2
sudo docker run -it --name=mytfcontainer tensorflow/tensorflow:latest bash

# for tensorflow GPU image with python 3
sudo docker run -it --runtime=nvidia --name=diwanshu1 tensorflow/tensorflow:latest-gpu-py3 bash

There you have it. Enjoy using tensorflow in docker
