OpenCV CUDA backend
Hey all!
I have a question: can I use OpenCV 4.2.0 with CUDA backend on device with 5.0 capability? It's support? Or only 5.3 and more supported?
Now after compile and run code I have an error:
OpenCV Error: Gpu API call (invalid device function)
When I try to set CUDA_ARCH_BIN=5.0
in CMake options, its doesnt compile with error:
CUDA backend for DNN module requires CC 5.3 or higher. Please remove unsupported architectures from CUDA_ARCH_BIN option
When I try to set CUDA_ARCH_BIN="5.3 6.0 6.1 7.0 7.5"
and CUDA_GENERATION=Auto
in CMake options, its doesnt compile with the same error.
My current options:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=~/opencv-4.2.0/opencv_contrib/modules -D OPENCV_ENABLE_NONFREE=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_FORCE_PYTHON_LIBS=ON -D PYTHON3_EXECUTABLE=~/anaconda3/envs/yolo-gpu/bin/python -D PYTHON3_LIBRARY=~/anaconda3/envs/yolo-gpu/lib/libpython3.6m.so -D PYTHON3_INCLUDE_DIRS=~/anaconda3/envs/yolo-gpu/include -D PYTHON3_NUMPY_INCLUDE_DIRS=~/anaconda3/envs/yolo-gpu/lib/python3.6/site-packages/numpy -D WITH_CUDA=ON -D BUILD_opencv_cudacodec=OFF -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-10.0 -D CUDA_ARCH_BIN=5.3 -D CUDA_ARCH_PTX=5.3 -D BUILD_EXAMPLES=ON ..
Its compile but doesnt work.
What can I do?
CUDA 10.0, CUDNN 7.6, GeForce 940M with 5.0 compute capability.
Please use OpenCV 4.3. All devices are supported now.
