ray.rllib.algorithms.algorithm_config.AlgorithmConfig

class ray.rllib.algorithms.algorithm_config.AlgorithmConfig(algo_class=None)

Bases: ray.tune.tune._Config

A RLlib AlgorithmConfig builds an RLlib Algorithm from a given configuration.

Example

>>> from ray.rllib.algorithms.algorithm_config import AlgorithmConfig
>>> from ray.rllib.algorithms.callbacks import MemoryTrackingCallbacks
>>> # Construct a generic config object, specifying values within different
>>> # sub-categories, e.g. "training".
>>> config = AlgorithmConfig().training(gamma=0.9, lr=0.01)  
...     .environment(env="CartPole-v1")
...     .resources(num_gpus=0)
...     .rollouts(num_rollout_workers=4)
...     .callbacks(MemoryTrackingCallbacks)
>>> # A config object can be used to construct the respective Trainer.
>>> rllib_algo = config.build()  

Example

>>> from ray.rllib.algorithms.algorithm_config import AlgorithmConfig
>>> from ray import tune
>>> # In combination with a tune.grid_search:
>>> config = AlgorithmConfig()
>>> config.training(lr=tune.grid_search([0.01, 0.001])) 
>>> # Use `to_dict()` method to get the legacy plain python config dict
>>> # for usage with `tune.Tuner().fit()`.
>>> tune.Tuner(  
...     "[registered trainer class]", param_space=config.to_dict()
...     ).fit()
