A minimal, well-documented PyTorch implementation of Proximal Policy Optimization (PPO) designed as a companion to a Medium tutorial series for reinforcement learning beginners. It follows OpenAI Spinning Up pseudocode with clearly annotated algorithm steps and assumes continuous observation and action spaces.

Use cases

• learn how to implement PPO from scratch in PyTorch
• understand policy gradient algorithms with readable code
• follow a step-by-step PPO tutorial series
• study a clean reference PPO implementation without fancy tricks
• train and test a PPO agent on a continuous control environment
• adapt a simple PPO baseline for my own RL experiments

When to choose

• you are new to reinforcement learning and want a readable PPO walkthrough
• you want code mapped line-by-line to Spinning Up pseudocode
• you prefer a bare-bones implementation over production RL frameworks
• you want to learn by modifying a small, well-styled codebase

When to avoid

• you need a production-grade, high-performance RL library
• you need discrete action spaces out of the box
• you want vectorized environments, distributed training, or many built-in tricks
• you need a maintained library with frequent updates and broad environment support
