Thanks for your post. I have tried others like this one and I cannot get past this error when trying to install on Raspbian. Below is my cmake command that does not include the explicit python version parameters.

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_opencv_java=OFF -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=OFF -D BUILD_EXAMPLES=OFF -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.4.1/modules -D WITH_CUDA=OFF ..

Is OpenCV only supported with python 3 and can this be why I get the following results?

I have been working on this for three days with little success. Any suggestions will be greatly appreciated.
