Dependencies

Most of the dependencies are listed in the requirements.txt file, and can be installed using the command

pip install -r requirements.txt

Make sure to install the gym package that is provided locally instead of the latest version to ensure compatibility

pip install -e gym

To run the 7D PR2 experiments, we need additional dependencies given in the external/ folder that can be installed as follows

pip install -e external/pyglet
pip install -e external/pyopengl
pip install -e external/urdfpy

Reproducing Experiments

Simulated 4D Planar Pushing

To run the experiments corresponding to the fetchpush environment (Table I in paper and Fig 2 (right)) run the following command inside src/ folder

python -m odium.experiment.experiment_fetch --exp-agent <agent> --exp-model <model>

where <agent> should be one of {'rts', 'dqn', 'mbpo', 'mbpo_knn', 'rts_correct'} where

• rts corresponds to our approach,
• dqn corresponds to Q-learning
• mbpo corresponds to Model learning with neural network model (NN)
• mbpo_knn corresponds to Model learning with K-nearest neighbors model (KNN)
• rts_correct corresponds to always planning with accurate model,

and <model> should be one of {'accurate', 'inaccurate'}.
