First, you will need an NVIDIA Jetson. Then you will need to install the operating system. To do this, you will need to flash a micro USB with NVIDIA's Jetpack image. The Jetpack image consists of a base Ubuntu image with many of the dev tools you will need in order to get going. Once you have your OS image, put it into the Jetson with a monitor, keyboard, mouse, and network-attached.
Then you will update the OS, as follows:
sudo apt-get update
After that, you will need to install the extra software to run the code:
sudo apt-get install git
sudo apt-get install cmake
sudo apt-get install libpython3-dev
sudo apt-get install python3-numpygpu sbc
Once you have done that, you will need to download the starter project from Jetson:
git clone --recursive https://github.com/dusty-nv/jetson-inference
Then you will make and navigate to the build directory:
cd jetson-inference
mkdir build
cd build
From here we will make, install, and link the code from the repository:
cmake ../
make...
