- RolloutWorker.sample_and_learn(expected_batch_size: int, num_sgd_iter: int, sgd_minibatch_size: str, standardize_fields: List[str]) Tuple[dict, int] #
Sample and batch and learn on it.
This is typically used in combination with distributed allreduce.
expected_batch_size – Expected number of samples to learn on.
num_sgd_iter – Number of SGD iterations.
sgd_minibatch_size – SGD minibatch size.
standardize_fields – List of sample fields to normalize.
- A tuple consisting of a dictionary of extra metadata returned from
learn_on_batch()and the number of samples learned on.
