How to visualize a RL trained model?

Post by underactuated »

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 18.04, the visualization step does not work any more, either producing some obscure error message or just hanging. Are there any alternative ways to create visualization?

Thank you very much for your helpful answers.
