[Alpha.Chen]

Hello~
I try use this url Tutorial to install opencv on jetson AGX Orion .

[Cuda Enabled OpenCV 4.5.4 Installation Debian Package for JP5]( Cuda Enabled OpenCV 4.5.4 Installation Debian Package for JP5 - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums)

theese is my jetson_release:

sudo jetson_release 
Software part of jetson-stats 4.2.12 - (c) 2024, Raffaello Bonghi

and i export some path to ~/.bashrc

export PYTHONPATH=/usr/local/lib/python3.8/site-packages/:$PYTHONPATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

But use python import have errors:

ubuntu@EAC-5000:/usr/local/lib/python3.8/site-packages/cv2$ /usr/bin/python3 /home/ubuntu/workspace/tests/cuda_test.py
Traceback (most recent call last):

    return _bootstrap._gcd_import(name[level:], package, level)

I want to use cv2 with nvidia driver
How can I fix it?

Hi,

Could you try our script to see if it works?

JEP/script at master · AastaNV/JEP

Thanks.

Thanks your reply,
I tried install_opencv4.6.0_Jetpack5.sh
But run
sudo apt-get install -y libv4l-dev v4l-utils qv4l2 v4l2ucp

Output :

libjpeg-dev is already the newest version (8c-2ubuntu8).
libpng-dev is already the newest version (1.6.37-2).
libdc1394-22-dev is already the newest version (2.2.5-2.1).
libtbb-dev is already the newest version (2020.1-2).
libtbb2 is already the newest version (2020.1-2).
libtiff-dev is already the newest version (4.1.0+git191117-2ubuntu0.20.04.14).

Does v4l2ucp still install?
or change other package name?
Thanks!

And I tried do theese:

1. I tried Install cuda library and cuda-tool-kit

sudo apt install nvidia-cuda
sudo apt-get install cuda-toolkit-11-4
ls /usr/local
ls /usr/local/cuda-11.4
cat ~/.bashrc

Output:

2. Re run jetson_release
   Output:
   

3. Use python run:

import cv2
print(cv2.cuda.getCudaEnabledDeviceCount())

Output is 0
Mean opencv can’t run with cuda

🤔

The cuda version have any problem?

Thanks!

It should be installed nvidia-jetpack first before installing opencv.
If I were you, I would reflash the AGX Orin
After that, I will install nvidia-jetpack and opencv.
You don’t need to worry about CUDA version if you install nvidia-jetpack.

sudo apt update
sudo apt install nvidia-jetpack

If the install script is not working after all above you should build the opencv source code.

Because My Jetson Some Custom Hardware
I try Flash Custom BSP Image.

Then use NVIDIA SDK Manager uncheck Linux image Flash

And Checked other want install libarary,

Powerup jetson to Desktop,

Use ifconig look your netcard ip,

Input userID and Password ,

Then use NetLine connect Jetson(This step Use SSH)

Then wait NVIDIA SDK Manager run to success.

Then reboot Jetson.

And run your post method:
Cuda Enabled OpenCV 4.5.4 Installation Debian Package for JP5 - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums

Then all success !!!

Thanks!
