Hi, I installed BalenaOS into a Jetson Xavier device and I have a Jetson Xavier container pushed to the fleet. I want to install tensorRT, cuda etc but I can’t figure out whether or not I have a Nvidia JetPack installed and which version it is Where can see that information from the balena OS, container, image or even docker hub ? I just want know exactly what I have installed ---

Hello, The best way is to check at source (search for L4T): [balena-jetson/CHANGELOG.md at master · balena-os/balena-jetson · GitHub](https://github.com/balena-os/balena-jetson/blob/master/CHANGELOG.md) ---

Another good solution, if you have a running device, is to run: `uname -a` it will tell you which L4T it’s running on.
