[Solved] import rviz results to librviz_sip module not found

I tried to compile ROS kinetic for python3 support with all packages included in desktop-full. I changed all references of python2 to python3 as well as changed some python2 print to python3 print. Compilation log did not show any errors. Compiled ROS using catkinmakeisolated. I have also sourced the setup.bash.

Problem: When trying to import rviz in python3, I get ImportError: No module named librvizsip. however in my lib/python3/dist-packages/rviz path, librvizsip.so is clearly there. If I run python3 in that same folder where librviz_sip.so is located and imported rviz, the import is successful. So I might not be setting some environment variables correctly.

Has anyone encountered this error when compiling ros for python3 support?

Apparently, the rviz version included in the kinetic release does not search for librviz_sip using relative directory. According to https://github.com/ros-visualization/rviz/pull/1454/commits/b02ff2e0d43b064250805e29dddd1ffc124e335a the changes in that commit fixes this.

I made these changes in my src/rviz/src/python_bindings/init.py, recompiled rviz, and rviz got imported correctly. I am encountering the same error in tf, so perhaps a similar fix can be done as well.
