I have build a docker container from nvidia/cuda:1.0-base
After I installed the system and python dependencies in the readme, I execute catkin build rangenet_lib, but the following error occurred:
ImportError: "from catkin_pkg.package import parse_package" failed: No module named catkin_pkg.package
Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.
CMake Error at /home/zhjw/code/catkin_ws/src/catkin/cmake/safe_execute_process.cmake:11 (message):

returned error code 1
I verified that the library can be imported correctly, as shown below:
**root@c15a10bf59a9:/home/zhjw/code/catkin_ws/src/rangenet_lib# python3
Python 3.6.9 (default, Jan 26 2021, 15:33:00)

Type "help", "copyright", "credits" or "license" for more information.
from catkin_pkg.package import parse_package

It seems like a version conflict between python and catkin_pkg. I never met such an error before. I will leave this issue open and see whether others can provide any help.
