mujoco-py provides Cython-based Python 3 bindings for the MuJoCo physics engine, enabling rigid body simulation with contacts from Python. It is now deprecated and users should switch to the official DeepMind MuJoCo Python bindings.
Use cases
- simulate rigid body physics with contacts from python
- run mujoco environments for reinforcement learning research
- load and step mujoco xml models in python
- reproduce legacy gym robotics environments
- simulate humanoid and other articulated models
When to choose
- maintaining legacy code that depends on mujoco-py or mujoco 2.1.0
- reproducing older reinforcement learning benchmarks that require mujoco-py
When to avoid
- starting a new project - use the official DeepMind MuJoCo Python bindings instead
- you need MuJoCo versions after 2.1.0
- you need Windows support
- you want actively maintained software
