This repository contains the code for BaRC: Backward Reachability Curriculum for Robotic Reinforcement Learning by Boris Ivanovic, James Harrison, Apoorva Sharma, Mo Chen, and Marco Pavone
git clone https://github.com/StanfordASL/BaRC.git cd BaRC # or wherever you cloned the repo # openai/baselines requires Python 3.5, so we enforce it too. conda create --name backreach python=3.5 source activate backreach pip install numpy matplotlib scipy
This repository depends on OpenAI Gym, OpenAI Baselines, and OpenMPI (because of Baselines). Further, our code requires MATLAB as well as the helperOC and Level Set Methods toolboxes for backward reachability computations.
For a minimal installation, you can install OpenAI Gym and Baselines like so:
cd gym pip install -e '.[mujoco,atari,classic_control,robotics]' cd ../code/baselines pip install -e .
With those obtained, you must place our two gym environments
PlanarQuad-v0 located in the
gym/ folder into your gym installation. Instructions for how to do this can be found on the OpenAI gym website.
Then, place our modifications to the baselines PPO algorithm into your installation of OpenAI baselines. They are located under
code/baselines/. For this, you simply replace the
ppo1 folder in the baselines repository with ours.
Now you're ready to use our code.
train.py is the main runner interface which can be called with command line arguments.
