OpenCV CUDA - Jetpack 6 Support

[starlight-traveler]

Hello,

With the advent of Jetpack 6.0 and with it Ubuntu LTS 22.04, I was inquiring whether or not the scripts would be updated to support the newest edition.

Some of the packages have been superseded or are not available, though I think running the commands manually still works.

Noted. I will address the issue soon. Update 2-11-2023: I can't install the pre-released JetPack 6 on my Jetson Orin Nano. It loops during bootup. Let's wait a few weeks for the official version 6 release.

Ahh, you would need to follow this thread, if you installed via SD Image or regular Nvidia SDK then the QSPI won't recognize it. Been an error for months:

No problem though!

Hey there @starlight-traveler and @Qengineering, I have the AGX Orin running Jetpack 6-dp and was able to update the 4.9 script to work. Jetpack 6 uses Cuda 12.2 and I believe that is why 4.8 wouldn't work for me when I tried. Below is the updated script for 4.9. I hope this is helpful!

#!/bin/bash set -e install_opencv () {

Check if the file /proc/device-tree/model exists

if [ -e "/proc/device-tree/model" ]; then # Read the model information from /proc/device-tree/model and remove null bytes model=$(tr -d '\0' < /proc/device-tree/model) # Check if the model information contains "Orin" echo "" if [[ $model == "Orin" ]]; then echo "Detecting an NVIDIA Orin Device." # Use always "-j 4" NO_JOB=4 ARCH=8.7 PTX="sm_87" elif [[ $model == "Jetson Nano" ]]; then echo "Detecting a regular Jetson Nano." ARCH=5.3 PTX="sm_53" # Use "-j 4" only swap space is larger than 5.5GB FREE_MEM="$(free -m | awk '/^Swap/ {print $2}')" if [[ "FREE_MEM" -gt "5500" ]]; then NO_JOB=4 else echo "Due to limited swap, make only uses 1 core" NO_JOB=1 fi else echo "Unable to determine the Jetson model." exit 1 fi echo "" else echo "Error: /proc/device-tree/model not found. Are you sure this is a Jetson Product?" exit 1 fi

@robbiesrobotics1 ,

Thanks for your contribution.

One question. Where is the difference? Both scripts look identical to me.

[robbiesrobotics1]

@Qengineering no problem at all! I just made a couple changes to the packages installed because there were two in the old script that aren't available for 22.04.

1. libdc1394-22-dev wasn't available so I used libdc1394-dev

2. libavresample-dev wasn't available so replaced with libswresample-dev

3. At first the script wouldn't run on my AGX because it wasn't a Nano so in the if statement when checking for device I just changed the device or "Orin" so that any orin series device would be detected. Post install I was able to verify opencv 4.9.0-dev with cuda in jtop. Additionally, after exposing the path to python3.10 I'm also able to see opencv with cuda in python.

[Qengineering]

@robbiesrobotics1 I've updated the script with your suggestions. Thanks!

[robbiesrobotics1]

@Qengineering no problem at all! I'm glad it was helpful.

Question. Are you using JetPack 6? And have you installed OpenCV with the script? It seems quite an ordeal to get it running. See issue #24. And https://forums.developer.nvidia.com/t/build-python-opencv2-with-cuda-support-for-jetpack-6-0/289016/3
