I have built OpenCV 4.7.0-dev from source on Ubuntu with CUDA 10.2 and compute capability 5.3. When I run my DNN with CPU I have no issues however setting the backend and target to CUDA gives me the error:
OpenCV(4.7.0-dev) /opencv/modules/dnn/src/cuda/padding.cu:155: error: (-215:Assertion failed) inShape[j] = outShape[j] in function ‘copy_with_reflection101’
I am using blob size of 2 x 3 x 1152 x 1024, and the output of my DNN is also 2 x 3 x 1152 x 1024 (a semantic segmentation network). This is the code that causes the problem:
net.setPreferableBackend(dnn::DNN_BACKEND_CUDA);
net.setPreferableTarget(dnn:DNN_TARGET_CUDA);
And this is my CUDA device info obtained via cuda::printCudaDeviceInfo(0)
