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. Web# Sample batches of this size are collected from rollout workers and # combined into a larger batch of `train_batch_size` for learning. # # For example, given rollout_fragment_length=100 and train_batch_size=1000: # 1. RLlib collects 10 fragments of 100 steps each from rollout workers. # 2.
