I got a Jetson Orin Nano installed with Nvidia SDK manager running Ubuntu 22.04, and would like to use R with these GPU.  And I have R 4.4.2 installed, how to verify my Jetson devloment boad is setup correctly and I could usW R to do some work?

1. Verify Jetson Orin Nano Setup

alexlai@jetsonOrinNano:~$ cat /etc/nv_tegra_release

R36 (release), REVISION: 4.0, GCID: 37537400, BOARD: generic, EABI: aarch64, DATE: Fri Sep 13 04:36:44 UTC 2024

2. Check CUDA Installation

alexlai@jetsonOrinNano:~$ nvcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2021 NVIDIA Corporation Built on Thu_Nov_18_09:45:25_PST_2021 Cuda compilation tools, release 11.5, V11.5.119 Build cuda_11.5.r11.5/compiler.30672275_0

alexlai@jetsonOrinNano:~$ ls /usr/local/cuda

alexlai@jetsonOrinNano:~$ ls -l /usr/local/cuda/bin/ total 0 lrwxrwxrwx 1 root root 13 十二 10 09:36 nvcc -> /usr/bin/nvcc


3. Install R and GPU-Compatible Libraries

alexlai@jetsonOrinNano:~$ R

1. check /etc/nv_tegra_release

alexlai@jetsonOrinNano:~$ cat /etc/nv_tegra_release

2.  nvcc --version


3. Reinstall OpenCL Libraries
