Different system versions

[Yajoker]

Hello, I'm very sorry to bother you. I'm a beginner. My Ubuntu version is 22.04, which does not support foxy. If I want to change to humble, what do I need to change in the code? Thanks.

Hi
I am not sure what changes are required between Foxy and Humble. You might need to change how ros nodes are called in https://github.com/reiniscimurs/DRL-Robot-Navigation-ROS2/blob/main/src/drl_navigation_ros2/ros_nodes.py

But you could also use a docker image to run the foxy version of the code.
