Implementation of Learning to Adapt in Dynamic, Real-World Environment through Meta-Reinforcement Learning. The code is written in Python 3 and builds on Tensorflow. The environments require the Mujoco131 physics engine.
If not installed yet, set up docker on your machine. Pull our docker container iclavera/learning_to_adapt from docker-hub:
docker pull iclavera/learning_to_adapt
All the necessary dependencies are already installed inside the docker container.
Ensure that you have a working MPI implementation (see here for more instructions).
For Ubuntu you can install MPI through the package manager:
sudo apt-get install libopenmpi-dev
If not done yet, install anaconda by following the instructions here
conda env create -f docker/environment.yml
For running the environments, the Mujoco physics engine version 131 is needed. For setting up Mujoco and mujoco-py
The run scripts are located in the folder run_scripts.
In order to run experiments with GrBAL, run the following command:
python run_scripts/run_grbal.py
If instead, you want to run ReBAL:
python run_scripts/run_rebal.py
We have also implement a non-adaptive model-based method that uses random shooting or cross-entropy for planning. You can run this baseline by executing the command:
python run_scripts/run_mb_mpc.py
When running experiments, the data will be stored in data/$EXPERIMENT_NAME. You can visualize the learning process
by using the visualization kit:
python viskit/frontend.py data/$EXPERIMENT_NAME
