- fix a bug in MAPolicy: `buffer.rew = Batch()` doesn't change `buffer.rew` (thanks mypy) - polish examples/box2d/bipedal_hardcore_sac.py - several docs update - format setup.py and bump version to 0.2.7
Bipedal-Hardcore-SAC
- Our default choice: remove the done flag penalty, will soon converge to ~250 reward within 100 epochs (10M env steps, 3~4 hours, see the image below)
- If the done penalty is not removed, it converges much slower than before, about 200 epochs (20M env steps) to reach the same performance (~200 reward)
- Action noise is only necessary in the beginning. It is a negative impact at the end of the training. Removing it can reach ~255 (our best result under the original env, no done penalty removed).
