Experiments

Experiments consist of one or many RLlib YAML config files alongside a MARKDOWN file containing results, plots and a detailed description of the methodology.

All files are stored in a experiment folder under experiments/<env-name>/<experiment-name>.

• Tree observations w/ fully connected network
• Global observations w/ convnet

Setup

Using conda (recommended):

# with GPU support:
conda env create -f environment-gpu.yml

# or, without GPU support:
#conda env create -f environment-cpu.yml

conda activate flatland-env
pip install -r requirements.txt

Using pip:

# no GPU support:
pip install -r requirements.txt

You may need to install/update bazel: Ubuntu guide

Usage

Training example:

python ./train.py -f experiments/flatland_random_sparse_small/global_obs_conv_net/ppo.yaml

Evaluation example:

python ./rollout.py /tmp/ray/checkpoint_dir/checkpoint-0 --run PPO --no-render --config '{"env_config": {"test": true}}' --episodes 1000 --out rollouts.pkl

Note that -f overrides all other trial-specific command-line options.
