Using Direct Download Links

You can download the datasets manually through Google Drive. The folders each correspond to the dataset types described in Dataset Types.

Google Drive folder with all mimicgen datasets: link

Then, you should download the dataset with core folder in the path robomimic/core.

To reproduce our simulation benchmark results, install our conda environment on a Linux machine with Nvidia GPU. On Ubuntu 20.04 you need to install the following apt packages for mujoco:

$ sudo apt install -y libosmesa6-dev libgl1-mesa-glx libglfw3 patchelf

We recommend Mambaforge instead of the standard anaconda distribution for faster installation:

$ mamba env create -f conda_environment.yaml

but you can use conda as well:

$ conda env create -f conda_environment.yaml

Then we install the packages for mimicgen:

conda activate sdp

You can install most of the dependencies by cloning the repository and then installing from source:

cd <PATH_TO_YOUR_INSTALL_DIRECTORY>
git clone https://github.com/NVlabs/mimicgen_environments.git
cd mimicgen_environments
pip install -e .

There are some additional dependencies that we list below. These are installed from source:

• robosuite
  • Installation

    cd <PATH_TO_YOUR_INSTALL_DIRECTORY>
    git clone https://github.com/ARISE-Initiative/robosuite.git
    cd robosuite
    git checkout b9d8d3de5e3dfd1724f4a0e6555246c460407daa
    pip install -e .

  • Note: the git checkout command corresponds to the commit we used for testing our policy learning results. In general the master branch (v1.4+) should be fine.
  • For more detailed instructions, see here
• robomimic
  • Installation

    cd <PATH_TO_YOUR_INSTALL_DIRECTORY>
    git clone https://github.com/ARISE-Initiative/robomimic.git
    cd robomimic
    git checkout ab6c3dcb8506f7f06b43b41365e5b3288c858520
    pip install -e .

  • Note: the git checkout command corresponds to the commit we used for testing our policy learning results. In general the master branch (v0.3+) should be fine.
  • For more detailed instructions, see here
• robosuite_task_zoo
  • Note: This is optional and only needed for the Kitchen and Hammer Cleanup environments / datasets.
  • Installation

    cd <PATH_TO_YOUR_INSTALL_DIRECTORY>
    git clone https://github.com/ARISE-Initiative/robosuite-task-zoo
    cd robosuite-task-zoo
    git checkout 74eab7f88214c21ca1ae8617c2b2f8d19718a9ed
    pip install -e .

Lastly, please downgrade MuJoCo to 2.3.2:

pip install mujoco==2.3.2

Note: This MuJoCo version (2.3.2) is important -- in our testing, we found that other versions of MuJoCo could be problematic, especially for the Sawyer arm datasets (e.g. 2.3.5 causes problems with rendering and 2.3.7 changes the dynamics of the robot arm significantly from the collected datasets).

The conda_environment_macos.yaml file is only for development on MacOS and does not have full support for benchmarks.

$ python train.py

The results in our paper is evaluated every 50 epochs, after 100 epochs, you can get a result similar in our paper.

Within each experiment directory you may find in outputs folder:

├── config.yaml
├── metrics
│   └── logs.json.txt
├── train
│   ├── checkpoints
│   │   ├── epoch=0299-test_mean_score=6.070.ckpt
│   │   └── latest.ckpt
│   └── logs.json.txt

You can download ours SDP checkpoints manually through Google Drive.

Google Drive folder with our checkpoints: link

You can reload the link if it does not work.

You can save the checkpoints in /path/to/ckpt.

$ python eval.py --checkpoint /path/to/ckpt

Then you can get a similar multi-task results in our paper.
