Getting OpenCV to work with CUDA, "no kernel image is available..."

I have a Jetson Orin Nano, and I’d like to get OpenCV to use CUDA. I understand that this isn’t built in, so I followed instructions that I found at https://qengineering.eu/install-opencv-4.5-on-jetson-nano.html to install OpenCV 4.6. Since those instructions are for an older Jetson Nano, I modified the script to select the correct GPU:

CUDA_ARCH_BIN=8.0

This is specifically what I have found in forums for dealing with the error I’m getting, but it isn’t helping. Despite getting the version right, as far as I can tell, I still get this error when I try to do anything CUDA-related:

error: (-217:Gpu API call) no kernel image is available for execution on the device in function 'call' Aborted

Is 8.0 the right architecture/GPU? Are there tools I can install to diagnose this? What else can I do to figure out what’s going wrong here?

Thanks.

Hi @theosib, try CUDA_ARCH_BIN=8.7 for Orin instead. If you check the CUDA deviceQuery output, it is listed there:

/usr/local/cuda/samples/1_Utilities/deviceQuery$ ./deviceQuery

Thanks! I didn’t know about that. I guess I should spend some time looking through those samples. I’ve changed the version to 8.7 and will report back how it goes. Thanks!
