I had the same issue during my OpenCV installation.

We need to execute gen script manually (from /build one level up, in my case, from /opencv-3.4.3, for you, based on your opencv version is /opencv-3.4.1).

So, if you are in /build:

cd ..
python ./modules/python/src2/gen2.py ./build/modules/python_bindings_generator ./build/modules/python_bindings_generator/headers.txt
cd build
sudo make install
