Code release for Model-Based Visual Planning with Self-Supervised Functional Distances.
This repository includes the distance learning component of the MBOLD method. To learn video prediction models, we use the training code located at RoboNet, and to run control, we use the visual foresight codebase. In order to run MBOLD, you will need to use all three components. If you only want to perform distance learning, this repository will be sufficient.
To install the package, clone the repository and run pip install -e .
from the main directory containing setup.py
.
Install Meta-World: Please see the instructions here to install Meta-World to use the simulated environments.
Installing FAISS: To perform GPU-enabled negative training example sampling, this code uses the FAISS library. Please see this document for information about how to install the GPU version of FAISS.
To train a distance function, run
python classifier_control/train.py <path_to_experiment_config>
For example, to train the MBOLD distance function on the three object tabletop pushing task data, run
python classifier_control/train.py experiments/distfunc_training/q_func_training/tabletop_3obj/conf.py
To run control experiments or perform data collection, run
python run_control_experiment.py <path_to_experiment_config>
For example, to run MBOLD on the three object tabletop pushing task, run
python run_control_experiment.py experiments/control/tabletop_3obj/mbold/hparams.py
Note that running control experiments requires a trained video prediction model, a trained distance function, as well as a set of evaluation tasks (possibly downloaded from the below section).
We provide training datasets for each simulated environment (collected using a random policy) as well as evaluation tasks
used in comparisons in the paper here.
To train on these datasets, download the .zip file and unzip it in your preferred location. Then, set the parameter 'data_dir'
in the training configuration file to point to this directory.
