I want to add a _train_step method to RecurrentPPO from SB3-Contrib (see here : https://github.com/Stable-Baselines-Team/stable-baselines3-contrib). This method was available in hIll-a Stable Baselines 1 for PPO2 (see here : https://github.com/hill-a/stable-baselines/blob/master/stable_baselines/ppo2/ppo2.py) but is not available anymore in Torch based SB3... It is a way to do that ?
The reason why i need such method is i want to perform Continual Learning.
Thanks for answer.
