Setup

This section covers on the required build and execute environments along with the build system configuration

Host Machine configuration
CPU	X86 based Quad core
RAM	32GB Recommended
OS	Ubuntu 20.04
GPU	RTX 2080 and above

Development Software Stack installation on X86

First extract the release package and then run the below command to install the required dependencies on X86 platform

./engine/build/scripts/install_dependencies.sh

After the installation is completed the setup is ready to build or run GXF graph.

Development Software Stack installation on Jetson device

Flashing the Jetson device

Jetson device can be easily setup with the help of SDK Manager which is a gui based tool. Step-by-step installation guide can be found here: https://docs.nvidia.com/sdk-manager/download-run-sdkm/index.html#login Once the SDK Manager is installed, the device can be flashed with the help of mentioned command line interface. Appropriate BSP version has to be chosen to be provided as an argument to the sdkmanager. Below example makes use of jetpack 5.0.2 GA b149.

# Flash the device with JP 5.0.2 GA b149
sdkmanager --server https://urm.nvidia.com/artifactory/sw-sdkm-generic-local/server/jetson/933/sdkm-config/main/sdkml1_repo.json

After flashing is complete the device is ready to be used

Using the GXF package on the Jetson device

Untar the release tarball on host machine Change directory to the location where gxf is located and follow the below steps

./engine/build/scripts/install_dependencies.sh
./engine/build/scripts/install_dependencies_jetson.sh -u ubuntu -h <jetson_ip>
bazel build ...
# Deploy the app on jetson using the below command:
./engine/build/deploy.sh -p //gxf/test:all_test -d <jetpack_version> -h <jetson_ip> -b bazel --remote_user ubuntu
