  3. Configure catkin build to use python3. Point to your version of Python 3 on your system -
catkin config -DPYTHON_EXECUTABLE=/usr/bin/python3 -DPYTHON_INCLUDE_DIR=/usr/include/python3.5m  -DPYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so

For using custom environment :

conda create --prefix ./py3_ros python=3.6 
catkin config -DPYTHON_EXECUTABLE=/media/yupeng/Data/ros_ws/py3_ros/bin/python -DPYTHON_INCLUDE_DIR=/media/yupeng/Data/ros_ws/py3_ros/include/  -DPYTHON_LIBRARY=/media/yupeng/Data/ros_ws/py3_ros/lib/libpython3.6m.so
  • Install python3.6 dev following instructions here. After this you need python include folder to cpp include - export CPLUS_INCLUDE_PATH="$CPLUS_INCLUDE_PATH:/usr/include/python3.6m/
  • Install bullet - sudo apt-get install libbullet-dev for tf2_bullet
  • You might have to add C++ support for vision_opencv package

    pip3 install empy pip3 install pyyaml pip3 install rospkg
  2. mkdir install
  3. Build using catkin build
  4. To use these packages, add this to your python path - ${WORKSPACE_ROOT}/ros_python3_ws/install/lib/python3/dist-packages
