pyrealsense does not work for python3 on Jetson Nano

Currently, pyrealsense can work with python2, but it can not work with python3 (python 3.6.9).I was trying to follow the steps on the https://github.com/IntelRealSense/librealsense/tree/master/wrappers/python but I do not see anything built for python3 after make -j4 and sudo make install. Is there anyway to solve this problem?

( I used

• cmake ../ -DBUILD_PYTHON_BINDINGS:bool=true -DPYTHON_EXECUTABLE=[full path to the python3] to refer to python3 as the default).
