I have tried to set the damping parameter for joints to various values from 1 to 100000, but observed no effect in simulations. Am I doing it correctly? I simply set it as default joint parameters inside a URDF model file: <default> <joint armature="1" damping="100000" limited=&q...

I am experimenting with pybullet's reinforcement learning. It worked well on the ant model, but the model is made extra easy with the limits on motor angles. For example, if the policy outputs zero torques, the ant is not collapsing because of the motor limits. I modified the ant model, so each leg ...

When I had pybullet installed on ubuntu 14.04, I could train a model and visualize the result like this: 1) python -m pybullet_envs.agents.train_ppo --config=pybullet_ant --logdir=ant 2) python -m pybullet_envs.agents.visualize_ppo --logdir=ant/xxxxx --outdir=ant_video After upgrading to ubuntu 18.0...

I trained a model in the pybullet_ant environment with python -m pybullet_envs.agents.train_ppo --config=pybullet_ant --logdir=ant The trained model is now stored in ant/xxxxx (where xxxxx is a time-stamped subdirectory). Can I force train_ppo to load the trained model in a new training session? So ...
