Code for CoRL 2019 paper: HRL4IN: Hierarchical Reinforcement Learning for Interactive Navigation with Mobile Manipulators

Code release for the CoRL 2019 paper: HRL4IN: Hierarchical Reinforcement Learning for Interactive Navigation with Mobile Manipulators

The PPO implementation is partially adopted from pytorch-a2c-ppo-acktr-gail and habitat-api

Dependency

• torch==1.1.0
• torchvision==0.2.2

Installation

1. Install iGibson with the hrl4in branch.

cd $HOME
git clone --recursive https://github.com/StanfordVL/iGibson.git
cd $HOME/iGibson
git checkout --track origin/hrl4in
pip install -e .

2. Download iGibson assets.

wget https://storage.googleapis.com/gibson_scenes/assets_igibson.tar.gz -O /tmp/assets_igibson.tar.gz
tar -zxf /tmp/assets_igibson.tar.gz --directory $HOME/iGibson/gibson2
rm /tmp/assets_igibson.tar.gz

3. Install HRL4IN

cd $HOME
git clone --recursive https://github.com/ChengshuLi/HRL4IN.git 
cd $HOME/HRL4IN
pip install -e .

4. Copy the updated JR URDF file from this repo to iGibson's asset folder

cp $HOME/HRL4IN/hrl4in/envs/gibson/jr2_kinova.urdf $HOME/iGibson/gibson2/assets/models/jr2_urdf/jr2_kinova.urdf
