'''MuJoCo XLA (MJX)''' is a specialized extension of the [[MuJoCo]] physics engine, designed to run simulations on hardware supported by the XLA (Accelerated Linear Algebra) compiler via the JAX framework. Running single threaded physics simulation on the GPU is not very efficient. The advantage with MJX is that we can run environments in parallel on a hardware accelerated device. === Installation ===Install using: <syntaxhighlight lang="bash"> pip install mujoco-mjx </syntaxhighlight> == Colab Tutorial == A detailed tutorial demonstrating the use of MJX along with reinforcement learning to train humanoid and quadruped robots to locomote is available [https://colab.research.google.com/github/google-deepmind/mujoco/blob/main/mjx/tutorial.ipynb#scrollTo=MpkYHwCqk7W- here].
