Submodules

gym_nethack.agents module

class gym_nethack.agents.TestAgent(test_policy=None, **kwargs)

Bases: libs.rl.core.Agent

A Keras-RL agent for purely heuristic policies, i.e., no learning done, no neural network model required.

backward(reward, valid_action_indices, terminal)

Updates the agent after having executed the action returned by forward. If the policy is implemented by a neural network, this corresponds to a weight update using back-prop.

# Argument

reward (float): The observed reward after executing the action returned by forward. terminal (boolean): True if the new state of the environment is terminal.

# Returns

List of metrics values

compile()

Compiles an agent and the underlaying models to be used for training and testing.

# Arguments

optimizer (keras.optimizers.Optimizer instance): The optimizer to be used during training. metrics (list of functions lambda y_true, y_pred: metric): The metrics to run during training.

forward(observation, valid_action_indices)

Takes the an observation from the environment and returns the action to be taken next. If the policy is implemented by a neural network, this corresponds to a forward (inference) pass.

# Argument

observation (object): The current observation from the environment.

# Returns

The next action to be executed in the environment.
