I can 'fix' this by reversing the future callback order: But it feels like a hack to mess around with private variables within the future class. Any ideas? |

2020-12-26 14:20:49 -0500 | marked best answer | Advice on nav2 controller plugin I'd like to write a controller plugin for nav2 using a reinforcement learing based AI model. We are currently training a model in python, so it would be natural to write a python controller node. However, I'm note sure how easy that is. All the examples in the tutorials in nav2 (eg https://navigation.ros.org/tutorials/...) are in C++, and include or inherit base classes from nav2_core or nav2_util which I am not sure are available in Python. Is it easy to write a python node that has all the required interfaces to be loaded by the controller server? If not, I will have to consider loading the model in C++ and/or writing wrappers to python code. I am sure that is doable, I'm just far less familiar with C++. Thanks |
