# Linux - Initial Setup

### Install Intel® Distribution of OpenVINO™ Toolkit

Refer to [this page](https://software.intel.com/en-us/articles/OpenVINO-Install-Linux) for more information about how to install and setup the Intel® Distribution of OpenVINO™ Toolkit.

You will need the OpenCL™ Runtime Package if you plan to run inference on the GPU. It is not mandatory for CPU inference. 

### Install Nodejs and its dependencies

- This step is only required if the user previously used Chris Lea's Node.js PPA.

```
sudo add-apt-repository -y -r ppa:chris-lea/node.js
sudo rm -f /etc/apt/sources.list.d/chris-lea-node_js-*.list
sudo rm -f /etc/apt/sources.list.d/chris-lea-node_js-*.list.save
```
- To install Nodejs and Npm, run the below commands:
```
curl -sSL https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
VERSION=node_6.x
DISTRO="$(lsb_release -s -c)"
echo "deb https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee /etc/apt/sources.list.d/nodesource.list
echo "deb-src https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee -a /etc/apt/sources.list.d/nodesource.list
sudo apt-get update
sudo apt-get install nodejs
```

### Install the following dependencies

```
sudo apt update
sudo apt-get install python3-pip
pip3 install numpy
pip3 install paho-mqtt
