Get Your Jetson Nano Working


Step 1: Flash Operating System

Visit the official Nvidia Jetson Nano Getting Started Guide. Work through the Prepare for Setup, Writing Image to the microSD Card, and Setup and First Boot instructions, then return here.

Step 2: Install Dependencies

ssh into your vehicle. Use the the terminal for Ubuntu or Mac. Putty for windows.

Note: you can either proceed with this tutorial, or if you have Jetpack 4.4 installed, you can use a script to automate the setup. The script is located in donkeycar/install/nano/ You will need to edit line #3 of the script and replace the default password with your password. This script will install all Git repositories into a ~/projects directory. If you wish to use a different directory, you will need to change this as well (replace all instances of ~/projects with your desired folder path).

First install some packages with apt-get.

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
sudo apt-get install -y openmpi-doc openmpi-bin libopenmpi-dev libopenblas-dev

Next, you will need to install packages with pip:

sudo -H pip3 install -U pip testresources setuptools
sudo -H pip3 install -U futures==3.1.1 protobuf==3.12.2 pybind11==2.5.0
sudo -H pip3 install -U cython==0.29.21
sudo -H pip3 install -U numpy==1.19.0
sudo -H pip3 install -U future==0.18.2 mock==4.0.2 h5py==2.10.0 keras_preprocessing==1.1.2 keras_applications==1.0.8 gast==0.3.3
sudo -H pip3 install -U grpcio==1.30.0 absl-py==0.9.0 py-cpuinfo==7.0.0 psutil==5.7.2 portpicker==1.3.1 six requests==2.24.0 astor==0.8.1 termcolor==1.1.0 wrapt==1.12.1 google-pasta==0.2.0
sudo -H pip3 install -U scipy==1.4.1
sudo -H pip3 install -U pandas==1.0.5
sudo -H pip3 install -U gdown

# This will install tensorflow as a system package
sudo -H pip3 install --pre --extra-index-url tensorflow==2.2.0+nv20.6

Finally, you can install PyTorch:

# Install PyTorch v1.7 - torchvision v0.8.1
wget -O torch-1.7.0-cp36-cp36m-linux_aarch64.whl
sudo -H pip3 install ./torch-1.7.0-cp36-cp36m-linux_aarch64.whl

# Install PyTorch Vision
sudo apt-get install libjpeg-dev zlib1g-dev libpython3-dev libavcodec-dev libavformat-dev libswscale-dev

# You can replace the following line with wherever you want to store your Git repositories
mkdir -p ~/projects; cd ~/projects
git clone --branch v0.8.1 torchvision
cd torchvision
export BUILD_VERSION=0.8.1
sudo python3 install

Optionally, you can install RPi.GPIO clone for Jetson Nano from here. This is not required for default setup, but can be useful if using LED or other GPIO driven devices.

Step 3: Setup Virtual Env

pip3 install virtualenv
python3 -m virtualenv -p python3 env --system-site-packages
echo "source env/bin/activate" >> ~/.bashrc
source ~/.bashrc

Step 4: Install Donkeycar Python Code

  • Change to a dir you would like to use as the head of your projects.
mkdir -p ~/projects; cd ~/projects
  • Get the latest donkeycar from Github.
git clone
cd donkeycar
git checkout master
pip install -e .[nano]

Step 5: Install PyGame (Optional)

If you plan to use a USB camera, you will also want to setup pygame:

sudo apt-get install python-dev libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev libsdl1.2-dev libsmpeg-dev python-numpy subversion libportmidi-dev ffmpeg libswscale-dev libavformat-dev libavcodec-dev libfreetype6-dev

pip install pygame

Later on you can add the CAMERA_TYPE="WEBCAM" in

Next, create your Donkeycar application.
