Installation

MyoSuite uses git submodules to resolve dependencies. Please follow steps exactly as below to install correctly.

Requirements

• python >= 3.8 (if needed follow instructions here for installing python and conda)

• mujoco >= 2.3.6

Installing the pip package

conda create --name MyoSuite python=3.8
conda activate MyoSuite
pip install -U myosuite

(alternative) Installing from source

To get started with MyoSuite, clone this repo with pre-populated submodule dependencies

git clone --recursive https://github.com/facebookresearch/myosuite.git
cd myosuite
pip install -e .

Testing the installation

You can test the installation using

python -m myosuite.tests.test_myo

You can visualize the environments with random controls using the below command

python -m myosuite.utils.examine_env --env_name myoElbowPose1D6MRandom-v0

Note

On MacOS, the need of a launch_passive option might require that the Python script be run under mjpython i.e. mjpython -m myosuite.utils.examine_env –env_name myoElbowPose1D6MRandom-v0

Examples

It is possible to create and interface with MyoSuite environments like any other OpenAI gym environments. For example, to use the myoElbowPose1D6MRandom-v0 environment it is possible simply to run:

from myosuite.utils import gym
env = gym.make('myoElbowPose1D6MRandom-v0')
env.reset()
for _ in range(1000):
  env.mj_render()
  env.step(env.action_space.sample()) # take a random action
env.close()

By default it will activate the simulator and the following visualization is expected:
