How to install OpenCv in stable Slicer 5.8.1?

Hi everyone!

I´m trying to install SlicerOpenCV in new stable release but it is not longer available.

I´ve tryed “slicer.util.pip_install(“opencv-python”)” and “slicer.util.pip_install(“opencv-contrib-python”)“ but I can´t still make “import cv2”

I there any way to do this?

Thanks
