SMC7-Semester-Project

Version control for the SMC7 project GitHub

NVIDIA Jetson

Set up the project on Jetson

1. Install Docker Compose

sudo curl -SL https://github.com/docker/compose/releases/download/v2.23.1/docker-compose-linux-aarch64 -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

2. Clone the repository to Jetson

git clone https://github.com/BjoernTroldahl/SMC7-Semester-Project.git

You will be asked for your github credentials during the clone process. Instead of your GitHub password use a personal access token which you can generate in the following way:

Create Personal Access Token on GitHub
From your GitHub account, go to Settings → Developer Settings → Personal Access Token → Generate New Token → Fillup the form → click Generate token → Copy the generated Token, it will be something like ghp_sFhFsSHhTzMDreGRLjmks4Tzuzgthdvfsrta

How to run inference on Jetson

1. Enter the repository and run docker-compose

cd SMC7-Semester-Project  
sudo docker-compose up -d

The first start-up will take longer since docker has to pull the container image from Nvidia’s repository

2. After you see a message that the container is running, you can access Jupyter through http://192.168.55.1:8888/ on the host computer
3. To acces the JupyterLab type in the password: Password: nvidia
4. Open the Camera Input to Model.ipynb notebook and run it
   • To make sure your Jetson will correcly send UDP packets to your MATLAB Plugin, you need to modify UDP_IP variable inside the notebook (How to send UDP from python cell). You can find your PC's IP by opening a Windows command line and running the ipconfig command.
5. After finishing work with notebooks you can stop docker with a docker compose down comand:

sudo docker-compose down

2. Go to this project location

cd <path_to_project>

3. Set required PATH variables. In case you have a different version of MATLAB installed correct the path in the command.

set PATH='<path_to_matlab>\bin\win64'%PATH%;

Ex. set PATH='C:\Program Files\MATLAB\R2023a\bin\win64'%PATH%;
