Force is a library for reinforcement learning research, built on TensorFlow and OpenAI Gym. It is under active development. Basic features at present:

• Tools for running experiments and logging results
• An implementation of the proximal policy optimization algorithm
• Flexible callback system for inserting custom behavior without rewriting the core functionality

The name "Force" was originally derived from the word reinforcement, but, by a fun coincidence, it is also related to one of my advisors via Newton's second law.
