Welcome to the-world of SheepRL, a robust reinforcement learning (RL) framework built atop PyTorch, specifically designed for easy and scalable implementations of various RL algorithms. This blog post will guide you through the process of installing SheepRL and running your first experiment. Let’s get into it!

Understanding SheepRL

Imagine you’re a shepherd steering your flock through challenging terrains. In the same way, SheepRL acts as a guide for various RL algorithms, directing them through the complexities of training and evaluation in diverse environments. Just as different terrains require unique strategies to navigate, SheepRL supports multiple algorithms and environments tailored to specific needs.

Installation Steps

Before diving into experiments, you need to have SheepRL installed. There are three ways to do this:

• Install from PyPi:

  pip install sheeprl

  To install optional dependencies run:

  pip install sheeprl[atari,box2d,dev,mujoco,test]

• Clone and Install Locally:

  git clone https://github.com/Eclectic-Sheep/sheeprl.git
  cd sheeprl
  pip install .

• Install via GitHub Repo:

  # Create and activate a virtual environment
  python3 -m venv .venv
  source .venv/bin/activate
  # Install SheepRL
  pip install sheeprl @ git+https://github.com/Eclectic-Sheep/sheeprl.git

Running Your First Experiment

With SheepRL installed, you are ready to run an experiment! For example, to train a Proximal Policy Optimization (PPO) agent in the CartPole environment, execute:

python sheeprl.py exp=ppo env=gym env.id=CartPole-v1

If you installed from a cloned repo, use:

sheeprl exp=ppo env=gym env.id=CartPole-v1

To see all available algorithms, use:

python sheeprlavailable_agents.py

or

sheeprl-agents

Visualizing Results

After training an agent, you will find a logs folder containing all training logs. To visualize these logs, you can use TensorBoard:

tensorboard --logdir logs

This will enable you to see how well your agent is performing over time.

Troubleshooting Tips

While using SheepRL, you may encounter some issues. Here are some common troubleshooting tips:

• Ensure your Python version is compatible (Python 3.8 or later).
• If you face issues with installations, consider using Homebrew to first install SWIG.
• Install necessary Java JDK if working with MineRL or MineDojo environments.
