I failed to build Jetbot on my Jetson Nano 2G, configured and installed JetPack 4.6.2 with L4T 32.7.1. Please refer to the following 2 issues:
- https://github.com/NVIDIA-AI-IOT/jetbot/issues/560
- https://github.com/NVIDIA-AI-IOT/jetbot/issues/563
It looks to a conflict between Jetbot and TensorRT ???
