Building Opencv with Cuda and cudnn: setupnet dnn module was not built with cuda backend; switching to cpu. JETSON TX2

[AastaLLL]

Hi,

We got a topic that reports a similar issue:

setUpNet DNN module was not built with CUDA backend; switching to CPU

I am working with Object Detection ( training with YOLOv3) on Jetson Orin with OpenCV **OpenCV = 4.5.4** **Operating System / Platform => NVIDIA JETSON Orin (Tegra)** **Compiler => Visual Studio 2019** **CUDNN 8.6 and CUDA 11.4.** I have configured the opencv with cmake-gui, enabling, WITH_CUDNN=ON OPENCV_DNN_CUDA=ON ENABLE_FAST_MATH=1 CUDA_FAST_MATH=1 CUDA_ARCH_BIN=8.7 WITH_CUBLAS=1 WITH_CUDA=ON BUILD_OPENCV_DNN=ON BUILD_OPENCV_WORLD=ON OPENCV_EXTRA_MODULES=/path/opencv_contrib/modules PYTH…

It looks like the GPU support is turned off somehow.
We are checking this internally. Please wait for our update.

Thanks.
