Introduction
This subsection shows the steps to install the Holoscan SDK on a Jetson Orin board using a .deb package. It also shows how to perform some basic testing to confirm that the installation is correct by executing some of the examples included in the SDK package.
Installing Dependencies
CUDA is required to use the Holoscan SDK in Jetson platforms. Usually CUDA is installed by default when a board is flashed using SDKManager, but if CUDA is not installed use the following command to install it:
sudo apt update && sudo apt install -y cuda-toolkit-12-6
Keep in mind that previous command will install version 12.6 of CUDA, which is the official version supported in JetPack 6. It is recommend to use the CUDA version officially supported by the corresponding JetPack release.
Installing Holoscan SDK
For this guide, the Debian package installation method will be used. With this method, simply execute the following commands in the Jetson board:
sudo apt update # Install Holoscan SDK sudo apt install holoscan
It is important to know that this method will only install the C++ API as Python support is removed from the Holoscan SDK Debian package as of version 3.0.0.
Testing the SDK
After the installation process is completed the Holoscan SDK will be located in the path /opt/nvidia/holoscan, this path has the following contents:
nvidia@nvidia:/opt/nvidia/holoscan$ ls bin examples include lib NOTICE README
One easy way to verify that the Holoscan SDK installation was successful is to execute the included examples. You can execute the Hello World example by executing the following commands:
cd /opt/nvidia/holoscan/ ./examples/hello_world/cpp/hello_world
If the installation was completed successfully the following output will be displayed:
