During training, replay buffers are queried for a subset of the trajectories (either a sequential subset or a sample) to "replay" the agent's experience. In this colab, we … See more The Replay Buffer class has the following definition and methods: Note that when the replay buffer object is initialized, it requires the data_spec of the elements that it will store. This spec corresponds to the TensorSpec of … See more PyUniformReplayBuffer has the same functionaly as the TFUniformReplayBufferbut instead of tf variables, its data is stored in numpy arrays. This buffer … See more TFUniformReplayBuffer is the most commonly used replay buffer in TF-Agents, thus we will use it in our tutorial here. In TFUniformReplayBufferthe backing buffer storage is done by tensorflow variables … See more Now that we know how to create a replay buffer, write items to it and read from it, we can use it to store trajectories during training of our agents.
