Hello, I want to run OpenCV compiled with CUDA on Jetson TX2. What should I do? can you help me?

Thank you! Works flawlessly for version 4.8.1. Took around 3 hours to install on my Xavier NX Nvidia Dev Kit.

However, I also installed ROS Noetic before thus also has a pre-installed opencv version 4.2.0 (no cuda) from ROS. I just need to point my python path to the opencv version 4.8.1 instead of 4.2.0 version.

The cuda build worked on my new Orin Nano, JTOP is saying OpenCV 4.5.4 CUDA: YES ... now I need to learn how to enable cuda for opencv. do you have any recomindations, Jim?

I followed all your steps with my Jetson Nano 4GB to build OpenCV 4.8.0. I checked in Jtop, and it was recognizing "OpenCV: 4.8.0 with CUDA: YES." However, when I executed "print(cv2.getBuildInformation())", it showed OpenCV 4.1.1:General configuration for OpenCV 4.1.1 | Version control: 4.1.1-2-gd5a58aa75. What is the problrm?

Hi, I can't find the "build_opencv" folder in the "tmp" directory. I am using a Jetson Nano 4GB, and I followed your steps. Where can I find this folder?

Great content!!

Hy, actually I'm using orin nano 8gb. I have an issue building Opencv. I want to change cap_v4l.cpp inside opencv/modules/videoio/src in line 1001 in 4.5.4 version. The select () timeout warning is the one i need to change. I used tv.tv_sec = 0 so that select() won't wait for anything. But after i build it, in /tmp/Opencv i see it is not taking any changes that was made during build time. It is using default things itself. I'm actually downloading opencv and opencv-contrib and then making the changes and updating the path inside build_opencv. sh in ---- git clone line. Please help me 🙏

Thank you so much for your knowledge. Could you make a video to build YOLOv3 on Orin running with C script? Iam struggle with library dependency on that.

It works for me on my Jetson Orin, save my day, Thanks!!!

Another excellent video.
Could you please share how did you update the Python version? is this a Jetson Nano, or an Jenson Orin Nano? what Jetpack version are you using? Thanks!

Hi I am using ubuntu version 20.04 , iam running one opencv object detection application its taking load on cpu



When I check the status using jtop its showing opencv with Cuda status is yes

If I run
Import cv2
Print(cv2.cuda.getCudadevicecount())
Its giving 0 as output

Please suggest me how to solve this issue
And run my application using gpu

I attempted to install OpenCV 4.5.0, jetpack 4.6 and 7GB swap on my Jetson Nano 4GB and received this error message:

Do you wish to remove temporary build files in /tmp/build_opencv ?
(Doing so may make running tests on the build later impossible)
Y/N y
rm: cannot remove '/tmp/build_opencv/opencv/build/CMakeFiles/Progress/23': Permission denied

hello
i followed everything it worked i installed opencv 4.1.1 it shows cuda support
but its only when i use python not python3
what is the solution plz

Great videos and content, thank you :)

I have an issue using the Orin Nano dev kit. I've followed the steps, modified mdegans script to only build for arch_bin 8.7 with CUDNN version 8.6, as I understand is correct for 4.5.4 (took about 55 mins). The symptom I have is the same as @nickbeser5187....

error: OpenCV(4.8.0) /io/opencv/modules/dnn/src/onnx/onnx_importer.cpp:279: error: (-210:Unsupported format or combination of formats) Failed to parse

I've worked my way through the script and don't see anything wrong, any thoughts?

Thank you for your video. I was able to build opencv 4.5.4 on my Jetson Orin Nano. When I tried to modify the face_detection_yunet code following your instructions I got the following error: cv2.error: OpenCV(4.8.0) /io/opencv/modules/dnn/src/onnx/onnx_importer.cpp:279: error: (-210:Unsupported format or combination of formats) Failed to parse ONNX model: face_detection_yunet_2023mar.onnx in function 'ONNXImporter'
I;m not sure why this is occurring, but searching on the internet, suggests that this might be a path problem. Any ideas?

I was following your tutorial on how to build OpenCV with CUDA support. I am running on a Jetson Orin AGX. I followed your directions as closely as possible twice however I am getting the following errors while compiling cuda_compile_1_generated_gpu_mat.cu.o, it is complaining that in texture.hpp(61): error: texture is not a template

typedef texture<T, 0x02, cudaReadModeElementType> TexRef

Because I am only planning to run on arch 8.6, I only added that arch to the cmake flag and selected cuDNN 8.6

Any suggestions?

Thanks!

Jim

hello, thank you for your videos, i liked and subscribed!
Is there a reason why one would want to install other NVIDIA GPU architectures on one device? for example i have a jetson orin nano developer kit, would i even be able to use other architectures on this device?

thank you for your time

First of all, thank you so much for the video, I have a jetson xavier nx (P3518) and i just follow exactly the same procedure and the end it didn't work, neither in jtop or with cv2.getBuildInfomation() i get something about CUDA. Help 😢

Hello there are some issue with my system after installation there is one file should be present inside tmp which build opencv .but in my its not there, any solution?
