Jtop Not Detecting JetPack or GPU

Hi,

I’m experiencing an issue with jtop on my Thor setup. When I run jtop, the status bar shows:

  • “JetPack NOT DETECTED”

  • “NVIDIA GPU NOT DETECTED/AVAILABLE”

However, JetPack 7 is properly installed and the GPU is functioning (I can see it in nvidia-smi and can run GPU workloads).

System Configuration:

  • Device: NVIDIA Thor

  • OS: Ubuntu 24.04.3

  • JetPack: 7

  • CUDA: 13.0

Is there a compatibility issue with jtop and JetPack 7 on Thor? Or is there a configuration step needed to make jtop recognize the system?

Thanks for any help!

Please refer to A method to install jtop on Thor without --break-system-packages - Jetson & Embedded Systems / Jetson Thor - NVIDIA Developer Forums to see if can help.
