5 years ago I have successfully build this package, thank you!
I have created a pull request about python3-
And I have got another error with sample launch.

doneThis seemed because python3 environment did not have chainercv modules. and this error did not appear after instaling chainercv to python3 environment with pip3 command. Is there any way to mark python3 library dependencies in catkin package.xml?
In addition, I have still got an error while executing the launch after chainercv installation to python3.

5 years ago Did you do source ~/ros/coral_ws/devel/setup.bash before launching?

5 years ago I have succecfuly run the exapmle by building jsk_topic_tools and source the workspace.
I had tried to build the package following the instruction in README.md, but "catkin build" command had failed because "catkin_pkg" was not found during "catkin_tools_prebuild" process.
I suspect that this is because python3-catkin-pkg package is not installed in my computer and python3 environment in my pc cannot use catkin_pkg python module, but the python3-catkin-pkg debian package for ubuntu conflicts with python-catkin-pkg, and if I install python3-catkin-pkg package to my pc, my ROS environment will break.
Is there any way to build this package? Should I build python3-catkin-pkg from source?
