Learning to Weight Imperfect Demonstrations

This repository contains the PyTorch code for the paper "Learning to Weight Imperfect Demonstrations" in ICML 2021. Code for Atari experiments can be found in this repo.

Requirement

• Python 3.7
• torch 1.3.1
• gym 0.15.7
• mujoco 2.0.2.4
• numpy 1.16.2

Execute

• WGAIL

python wgail.py --env Ant-v2 --num-epochs 5000 --traj-size 1000 --stage 2

• 2IWIL

python 2iwil.py --env Ant-v2 --num-epochs 5000 --traj-size 1000 --stage 2

• GAIL
