3. Parallel Envs

In this tutorial, we will show you how to use MetaSim to run multiple environments in parallel.

Common Usage

python get_started/3_parallel_envs.py  --sim <simulator> --num_envs <num_envs>

you can also render in the headless mode by adding --headless flag. By using this, there will be no window popping up and the rendering will also be faster.

By running the above command, you will run multiple environments in parallel and it will automatically record a video.

Examples

Isaac Lab

python get_started/3_parallel_envs.py  --sim isaaclab --num_envs 4

Isaac Gym

python get_started/3_parallel_envs.py  --sim isaacgym --num_envs 4

Genesis

python get_started/3_parallel_envs.py  --sim genesis --num_envs 4

Note that we find the headless mode of Genesis is not stable. So we recommend using the non-headless mode.

We can open multiple environments at the same time.

You will get the following videos:
