Generating Data with MimicGen#

Given a modest number of source demonstrations, we offer the ability to syntehsize new trajectories with MimicGen.

Installation#

  1. Clone and setup MimicGen under the experimental/robocasa branch:

    git clone https://github.com/NVlabs/mimicgen -b experimental/robocasa
    cd mimicgen
    pip install -e .
    
  2. Setup the robomimic dependency:

    cd ..
    git clone https://github.com/ARISE-Initiative/robomimic -b robocasa
    cd robomimic
    pip install -e .
    

Generate data for existing tasks#

We have set up MimicGen for 24/25 existing atomic tasks. Generating demonstration datasets for these tasks is a 3 step process, which we illustrate for the PnPCounterToSink task:

(Note: these commands assume that datasets are stored under ~/robocasa/datasets)

  1. Extract subtask meta data:

    python mimicgen/scripts/prepare_src_dataset.py --dataset ~/robocasa/datasets/v0.1/single_stage/kitchen_pnp/PnPCounterToSink/2024-04-25/demo.hdf5
    
  2. Generate demonstartions:

    python mimicgen/scripts/generate_dataset.py --config mimicgen/exps/templates/robocasa/single_stage/kitchen_pnp/PnPCounterToSink.json
    
  3. Extract image observations. You can then extract image datasets following the dataset extraction tutorial on this guide.
