Jetpack 7.2 on orin nx

I am running JetPack 7.2 on an NVIDIA Jetson Orin NX (8GB module). While OpenCV 4.8 is pre-installed in this JetPack release, it lacks built-in CUDA acceleration. I followed the Q-Engineering source-compilation guide ( Install OpenCV on Jetson Orin Nano - Q-engineering ), attempting to build versions ranging from v4.8 through v4.13. Unfortunately, the compilation fails for every version. I need assistance with a compatible build procedure or CMake configuration to successfully enable CUDA support for OpenCV on this setup."

Hi,

Could you check if the package listed below works for you?

Thanks

I did not , no need to check as the ultralytics is perfectly working after the installation procedure followed given at : ("Quick Start Guide: NVIDIA Jetson with Ultralytics YOLO26 | Ultralytics Docs ").

  1. pip install ultralytics[export] > Reboot,
  2. pip install torch torchvision --index-url https://download.pytorch.org/whl/cu130
  3. pip install https://github.com/ultralytics/assets/releases/download/v0.0.0/onnxruntime_gpu-1.24.0-cp312-cp312-linux_aarch64.whl

. That’s it.

Actually, the above suggested site "sbsa/cu130 index" does not have the guide to install OpenCV 4.13 with CUDA v13.2 support.

Hi,

Solved:
I tried and edited some of the OpenCV V4.13 files and finally build from the source "OpenCV v4.13 with CUDA V13.2 support) on jetpack7.2.

Hi,

Good to know it works now.
Do you compile OpenCV from the source?

Thanks.

11

Yes, but after the patch.

22

Can You give the process you used as I always end up with compiler faults

23

Ok after the fourth attempt it finally worked using your patches.

I now have opencv 4.13 with cuda support on Jetpack 7.2 orin nano.
