From rl.memory import sequentialmemory

WebReinforcement Learning (RL) frameworks help engineers by creating higher level abstractions of the core components of an RL algorithm. This makes code easier to develop, easier to read and improves efficiency. But choosing a framework introduces some amount of lock in. An investment in learning and using a framework can make it hard to break away.
