Building an AI Racing League Image for the Car¶

This process takes about four hours and requires close attention to detail.

Install The Latest NVIDIA image¶

Enable SSH¶

This allows you to do a remote login to the car

sudo systemctl enable ssh
sudo systemctl start ssh

Test ssh:

ssh arl@arl-01

Add a swap file¶

The Jetson Hacks GitHub repo contains a nice UNIX script that will add a swap file.

git clone https://github.com/JetsonHacksNano/installSwapfile
cd installSwapfile
./installSwapfile.sh

You should reboot the Nano after you add this file.

Add HTOP¶

The standard UNIX top command does not display the load across multiple cores. The much more modern htop is preferred and has better use of color.

sudo apt-get install htop

Customize Browser Add the Bookmark Bar¶

AI Racing League
Donkey Car Docs

Remove Unused Software¶

Ubuntu comes with several "Office" applications for doing word-processing, spreadsheets and presentations. These applications take up a lot of disk space so we will remove them.

sudo apt-get remove --purge libreoffice*
sudo apt-get clean
sudo apt-get autoremove

Upgrade Local Libraries¶

Download Donkey Car Dependencies¶

sudo apt-get update -y sudo apt-get upgrade -y sudo apt-get install -y libhdf5-serial-dev hdf5-tools libhdf5-dev zlib1g-dev zip libjpeg8-dev liblapack-dev libblas-dev gfortran sudo apt-get install -y python3-dev python3-pip sudo apt-get install -y libxslt1-dev libxml2-dev libffi-dev libcurl4-openssl-dev libssl-dev libpng-dev libopenblas-dev sudo apt-get install -y git nano sudo apt-get install -y openmpi-doc openmpi-bin libopenmpi-dev libopenblas-dev
