- Not doing the same mistake again. There are great tutorials on installing OpenCV by PyImage Search (see References), however they work for system-level Python with virtualenv. These are my notes on building OpenCV 3 with CUDA on Ubuntu 16.04 with Anaconda environment in case those tutorials did not work, e.g. you cannot find the cv2.so file. Setup

- Or would it make more sense to use the regular opencv recipes and add the cudatools as a dependency and cuda to the cmake configuration? Yes, one should even be able to use later OpenCV versions with regular CUDA acceleration. However whether or not and what version would be compatible with the older CUDA version 6.5 running on TK1 I do not know.

A CUDA-based GPU interface has been in progress since September 2010. An OpenCL-based GPU interface has been in progress since October 2012, documentation for version 2.4.13.3 can be found at docs.opencv.org. OS support. OpenCV runs on the following desktop operating systems: Windows, Linux, macOS, FreeBSD, NetBSD, OpenBSD. When trying to compile OpenCV 2.4.9 with CUDA 6.0 support, I get the following error: fatal error: cuda.h: No such file or directory. CUDA 6.0 seems to be running fine, nvcc works and the samples too. There is still an instance of CUDA5.5 on my computer. With that version I did not get nvcc to run, however it worked with OpenCV. Replace CUDA_GENERATION with a proper one. CUDA_GENERATION is used for specification of Auto, Fermi, Pascal, Maxwell or Volta, etc. and limits the code generation only for specific architecture.

Apr 22, 2020 · The guide below details instructions on compiling the 64 bit version of OpenCV 4.3.0 shared libraries with Visual Studio 2019, CUDA 10.2, and optionally the Nvidia Video Codec SDK, Nvidia cuDNN, Intel Media SDK, Intel Math Kernel Libraries (MKL), Intel Threaded Building Blocks (TBB) and Python bindings for accessing OpenCV CUDA modules from within Python. The opencv from sdkmanager only provides necessary lib/functions other sdk components need. For enabling python and cuda, the steps have no difference between upstream openCV, so I think you could directly follow the installation steps from other users.

Install OpenCV GPU. Standardly OpenCV has no support for GPU, which makes YOLO inference very slow – especially on a live video stream. Since OpenCV version 4.2, the dnn module supports NVIDIA GPUs. PyImageSearch has a great tutorial showing you how to compile and install OpenCV's dnn module with NVIDIA GPU, CUDA, and cuDNN support.
