GraphIRL is a self-supervised method for learning a visually invariant reward function directly from a set of diverse third-person video demonstrations via a graph abstraction. Our framework builds an object-centric graph abstraction from video demonstrations and then learns an embedding space that captures task progression by exploiting the temporal cue in the videos. This embedding space is then used to construct a domain invariant and embodiment invariant reward function which can be used to train any standard reinforcement learning algorithm.

We assume you have installed MuJoCo on your machine. You can install dependencies using conda:
conda env create -f environment.yaml
conda activate graphirl
You can use trained models to extract the reward and train a policy by running:
bash scripts/run_${Task_Name} /path/to/trained_model
The dataset for GraphIRL can be found in this Google Drive Folder. We have also released the trained reward models for Reach, Push and Peg in Box here.
We include a script for downloading all data with the gdown package, though feel free to directly download the files from our drive folder if you run into issues with the script.
