The only opencv\_contrib that I find available is only for cpu and if I use the opencv\_python it doesn´t recognize this method. Thanks in advance ---

Did you build with CUDA support? `-DWITH_CUDA=ON` ---

I simply installed with pip the python packages ---

If you want CUDA support you need to build yourself. The contrib module contains the CUDA modules however the [opencv\_contrib](https://pypi.org/project/opencv-contrib-python/) python wheel is not built with CUDA support. > Check the manual build section if you wish to compile the bindings from source to enable additional modules such as CUDA. ---

there are no prebuilt opencv libs with cuda support, you will have to build this from src (with cuda sdk installed) > **[GitHub - opencv/opencv\_contrib: Repository for OpenCV's extra modules](https://github.com/opencv/opencv_contrib/)** > > Repository for OpenCV's extra modules.

this is a pity, it would be really useful ---
