MyoSuite is a collection of musculoskeletal environments and tasks simulated with the MuJoCo physics engine and wrapped in the OpenAI gym API to enable the application of Machine Learning to bio-mechanic control problems.
Documentation | Tutorials | Task specifications
Below is an overview of the tasks in the MyoSuite.
Installations
You will need Python 3.8 or later versions.
It is recommended to use Miniconda and to create a separate environment with:
conda create --name myosuite python=3.8
conda activate myosuite
It is possible to install MyoSuite with:
pip install -U myosuite
for advanced installation, see here.
Test your installation using the following command (this will return also a list of all the current environments):
python -m myosuite.tests.test_myo
You can also visualize the environments with random controls using the command below:
python -m myosuite.utils.examine_env --env_name myoElbowPose1D6MRandom-v0
NOTE: On MacOS, we moved to mujoco native launch_passive which requires that the Python script be run under mjpython:
mjpython -m myosuite.utils.examine_env --env_name myoElbowPose1D6MRandom-v0
It is possible to take advantage of the latest MyoSkeleton. Once added (follow the instructions prompted by python -m myosuite_init), run:
python -m myosuite.utils.examine_sim -s myosuite/simhive/myo_model/myoskeleton/myoskeleton.xml
Examples
It is possible to create and interface with MyoSuite environments just 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()
