ManiSkill2 Data

Update: ManiSkill 3 has been released https://github.com/haosulab/ManiSkill/. It uses different datasets than ManiSkill2 so the data here is not expected to transfer over

ManiSkill2 is a unified benchmark for learning generalizable robotic manipulation skills powered by SAPIEN. It features 20 out-of-box task families with 2000+ diverse object models and 4M+ demonstration frames. Moreover, it empowers fast visual input learning algorithms so that a CNN-based policy can collect samples at about 2000 FPS with 1 GPU and 16 processes on a workstation. The benchmark can be used to study a wide range of algorithms: 2D & 3D vision-based reinforcement learning, imitation learning, sense-plan-act, etc. This is the huggingface datasets page for all data related to ManiSkill2, including assets, robot demonstrations, and pretrained models

For detailed information about ManiSkill2, head over to our GitHub repository, website, or ICLR 2023 paper documentation

Note that to download the data you must use the mani_skill2 package to do so as shown below, currently loading through HuggingFace datasets does not work as intended just yet

Assets

Some environments require you to download additional assets, which are stored here.

You can download all the assets by running

python -m mani_skill2.utils.download_asset all

or download task-specific assets by running

python -m mani_skill2.utils.download_asset ${ENV_ID}

Demonstration Data

The robot demonstrations consist of 4 million+ frames across 20+ robot manipulation tasks.

We provide a command line tool (mani_skill2.utils.download_demo) to download demonstrations from here.

# Download all the demonstration datasets
python -m mani_skill2.utils.download_demo all
# Download the demonstration dataset for a specific task
python -m mani_skill2.utils.download_demo ${ENV_ID}
# Download the demonstration datasets for all rigid-body tasks to "./demos"
python -m mani_skill2.utils.download_demo rigid_body -o ./demos
# Download the demonstration datasets for all soft-body tasks
python -m mani_skill2.utils.download_demo soft_body

To learn how to use the demonstrations and what environments are available, go to the demonstrations documentation page: https://haosulab.github.io/ManiSkill2/concepts/demonstrations.html
