Massively parallel rigidbody physics simulation on accelerator hardware.
Hello, I found two bugs and fixed them. I hope this will help brax. 1: When applying multiple forces to a body, the dimension of action only counts one of...
Not a major change, just some hyperlinks that were presumably broken by a refactor
I refactored the PPO/train code to increase its compatibility with check-pointing and environment variation, while keeping backwards compatibility This splits the train function into multiple functions: - make_train_space: a function...
I am trying to implement my own simulation of a robot claw. I have an issue where for some reason all the bodies are exploding. This is odd to me...
Hi, I have an extremely strange bug that is slightly hard to reproduce :) I am trying to integrate brax with SAC and want to use an ensemble version of...
Hi, I noticed the box-box collider pair is still unsupported. I was wondering this would be available anytime soon or can be easily addressed. Thanks!
`jp.arcsin` can produce a NaN in `quat_to_euler` under certain conditions, which suggests that `jp.norm(q)` > 1 + epsilon. This is probably a numerical issue tied to XLA - the bug...
Probably harmless but just in case: ``` Traceback (most recent call last): File "ppo_test.py", line 45, in testTrain self.assertGreater(metrics['eval/episode_reward'], 100 * 0.995) AssertionError: DeviceArray(97.05763, dtype=float32) not greater than 99.5 ```...
Currently it appears that composer/the multi-agent training only supports components with actuators acting on joints, and not external torques or thrusters. Are there plans to include these?
