Hi @trauts14, JetPack already comes pre-installed in the SD card image that you flashed.
For example, if you check your /usr/local/cuda directory, you should already find the CUDA Toolkit there (part of JetPack).
For an example of learning about object detection, you can refer to this tutorial:
- GitHub - dusty-nv/jetson-inference: Hello AI World guide to deploying deep-learning inference networks and deep vision primitives with TensorRT and NVIDIA Jetson.
