Reinforcement Learning Baselines

The goal of this repository is to learn a little more about reinforcement learning algorithms.

Stack:

  • Pytorch
  • Pytorch Lightning
  • TensorDict

Getting Started

Training

Example: To train the Reinforce algorithm, use the following command:

python scripts/launch.py --train --config configs/reinforce.yaml

You can customize the training parameters, such as the number of episodes. For example, to set the maximum number of training episodes to 500:

python scripts/launch.py --train --config configs/reinforce.yaml trainer.max_episodes=500

Evaluation

To evaluate your models, use the same launch.py script but with the --test flag. You'll also need to specify the configuration file and the checkpoint from the outputs folder. Here’s an example:

python scripts/launch.py --test --config outputs/reinforce-discrete/../parsed.yaml --resume=outputs/reinforce-discrete/.../checkpoint.ckpt

By default, this command will print the cumulative reward for each episode. If you'd like to render the environment and save a video, add the following options:

python scripts/launch.py --test --config outputs/reinforce-discrete/../parsed.yaml --resume=outputs/reinforce-discrete/.../checkpoint.ckpt system.environment.render=True --save-video
