Hi everybody!
jetson nano version : Jetpack 4.6.4
I am going to build opencv 4.1.1 with cuda on jetson nano 4G evaluation board.
and open cv version 4.1.1;
ı tyr this : GitHub - mdegans/nano_build_opencv: Build OpenCV on Nvidia Jetson Nano
The build was successful, but it appears as CUDA:No
please help
Hi,
Please try the below script but update the version to 4.1.1:
Thanks.
I got this error

I flashed Jetson, changed the file you suggested to 4.1.1 and ran it.
Hi,
Based on this error:
fatal error: Eigen/Core: No such file or directory
Please try to install the dependency.
$ sudo apt install libeigen3-dev
$ cd /usr/include
$ sudo ln -sf eigen3/Eigen Eigen
Thanks.
hi i reset the sd card and applied the following file.
Log file is attached. But it shows as Cudnn:No.
And should I make a setting to run open cv on GPU. I am new to this code, thank you for your help.

Hi,
cuDNN is used for neural network inference.
Based on your log, CUDA support is enabled.

Thanks.
That’s good to hear, it’s finally happened. But when I try to open the py file I attached, I get the following error.
net.setPreferableBackend(cv2.dnn.DNN_BACKEND_CUDA)
AttributeError: module 'cv2.dnn' has no attribute 'DNN_BACKEND_CUDA'
open cv version =4.1.1,
Python =3.6.9

I tried readNet and readNetFromDarknet the same error
You need OpenCV 4.2 or above to use “DNN_BACKEND_CUDA”.

I set it to 4.2.0 and built again, this time I get the attached error.

Hi,
As Mt.Hiker mentioned, if you want to use the OpenCV DNN function, you will need to build it with some extra flags.
For more details, please check below topic:
Thanks.

Hi,
Do you run it on the Jetson platform?
cannot find -laarch64-linux-gnu
The error indicates it cannot find the compiling tool.
Thanks.
