ericyangyu/PPO-for-Beginners

• highreadme#1

  Reposition README introduction to emphasize core value proposition

  Why:

  CURRENT

  Hi! My name is Eric Yu, and I wrote this repository to help beginners get started in writing Proximal Policy Optimization (PPO) from scratch using PyTorch. My goal is to provide a code for PPO that's bare-bones (little/no fancy tricks) and extremely well documented/styled and structured. I'm especially targeting people who are tired of reading endless PPO implementations and having absolutely no idea what's going on.

  COPY-PASTE FIX

  Copy

  This repository provides a **bare-bones, exceptionally well-documented, and clear PyTorch implementation of Proximal Policy Optimization (PPO)**, specifically designed for beginners to understand the core algorithm from scratch.

  How can I find a clear, well-documented PyTorch PPO implementation for beginners?

  you: not recommended
  AI recommended (in order):

  1. CleanRL (cleanrl/cleanrl)
  2. Stable Baselines3 (SB3) (DLR-RM/stable-baselines3)
  3. Minimal PPO by Misha Laskin
  4. PyTorch Reinforcement Learning (PyTorch-RL) by Suriyadeepan (Suriyadeepan/pytorch-rl)
