Request to Migrate from Master to Main Branch for Improved Stability

[abdul-mannan-khan]

Hi @JacopoPan
Thank you for your dedication to maintaining this project. I have noticed several issues with the master branch that seem to limit its functionality.

Could we consider transitioning the primary development and examples from the master to the main branch to enhance stability and clarity for new contributors? I believe this could help avoid the current issues and streamline future development.

I am eager to assist with this process to ensure a smooth transition. In particular, I am interested to produce the codes available in experiments folder which were developed for different cases in the master repository. For example, FlyThruGateAviary and I just need your kind guidance for the issues I face in this process. Thanks for considering this change.

Also, I have noticed that you have remove some of the Aviaries from the master branch from single_agent_rl folder such as TakeoffAviary and TuneAviary? I believe that we do not need them any more. Do we?
Following this, I have updated singleagent.py for simple hover. I have attached it here
singleagent_20240621.zip
and its test file is attached here
test_singleagent_20240621.zip
The files are inside zipped folder because I cannot attach .py files here. Can you please comment on it?

Thank you for your kind response.

Hello @abdul-mannan-khan
main is the current default branch of the repo, master is the original branch of this work (published in the form of branch paper), updated up until last year.

Because of the major changes in at least 3 of the main dependencies of this work (rllib, gym, stable-baselines3), I switched to maintaining main instead of master roughly one year ago: if you have made improvements/bugfixes to master I'm happy to include them (even if I don't use that branch anymore), my suggestion is to (1) fork it, (2) apply your corrections, (3) open a PR from your fork to master of this repo. I will review and merge those changes as appropriate.

Regarding FlyThruGate, I am getting following error

Traceback (most recent call last):

gymnasium.error.NameNotFound: Environment `flythrugate-aviary` doesn't exist. Did you mean: `ctrl-aviary`?

My flythrugate-aviary follows your same style as in the paper hover/flythrugate-aviary here.
FlyThruGateAviary.zip
and my flythrugate simulation file is singleagent_20240625a.zip.

Can you please help me run here?

Just to mention that __init__.py in gym_pybullet_drones/gym_pybullet_drones/envs has FlyThruGateAviary defined.

from gym_pybullet_drones.envs.BetaAviary import BetaAviary
from gym_pybullet_drones.envs.CtrlAviary import CtrlAviary
from gym_pybullet_drones.envs.HoverAviary import HoverAviary
from gym_pybullet_drones.envs.FlyThruGateAviary import FlyThruGateAviary
from gym_pybullet_drones.envs.MultiHoverAviary import MultiHoverAviary
from gym_pybullet_drones.envs.VelocityAviary import VelocityAviary

Thank you so much for your help.

I figured this out. I updated gym_pybullet_drones->__init__.py and updated the following part

register(
    id='flythrugate-aviary-v0',
    entry_point='gym_pybullet_drones.envs:FlyThruGateAviary',
)

The complete code is as follows:

from gymnasium.envs.registration import register

register(
    id='ctrl-aviary-v0',
    entry_point='gym_pybullet_drones.envs:CtrlAviary',
)

register(
    id='velocity-aviary-v0',
    entry_point='gym_pybullet_drones.envs:VelocityAviary',
)

register(
    id='hover-aviary-v0',
    entry_point='gym_pybullet_drones.envs:HoverAviary',
)

register(
    id='multihover-aviary-v0',
    entry_point='gym_pybullet_drones.envs:MultiHoverAviary',
)

register(
    id='flythrugate-aviary-v0',
    entry_point='gym_pybullet_drones.envs:FlyThruGateAviary',
)
