Deep RePReL

Combining Planning and Deep RL for acting in relational domains

This repository contains batch RL based implementation of RePReL with deep reinforcement learning as well as deep relational reinforcement learning. More details about the batch RePReL learning algorithm can be found in our paper here.

Implementation of Hybrid Deep RePReL to be added soon.

Installation

  1. Clone the github repo
$ git clone https://github.com/harshakokel/DeepRePReL.git ./DeepRePReL
$ cd DeepRePReL
  1. Create a python virtual env and installing the requirements
$ virtualenv -p python3 reprel_venv
$ source reprel_venv/bin/activate
(reprel_venv) $ pip install -r environment/reprel-requirements.txt
  1. Install gym environment and respective requirements.

Taxi domain and office world requirements

  • pip install git+https://github.com/harshakokel/RePReL-domains.git@main

FetchBlockConstruction domain requirements

  • pip install git+https://github.com/harshakokel/fetch-block-construction.git@master
  • pip install mujoco-py>=2.0.2
  1. Run experiments from examples. Refer to the RePReL documentation for more details.

The tabular reinforcement learning implementation is available in the other repository here.

The core of this repository is the RLkit library by RAIL Berkeley organization. ReNN code for FetchBlockConstruction domain is obtained from the rlkit-relational repository made available by the authors of Li et al. [1]. The repository also includes implementation of taskable RL framework proposed in Illanes et al. [2]
