MazeSeeding¶

class maze.core.utils.seeding.MazeSeeding(env_seed: int, agent_seed: int, cudnn_determinism_flag: bool)¶

Manages the random seeding for maze. This class holds random state used for sampling random seed for the envs and agents.

Parameters

env_seed – The base_seed to be used for the envs random number generator.
agent_seed – The base_seed to be used for the agents random number generator.
cudnn_determinism_flag – Specify whether to set the cudnn determinism flag, this will ensure guaranty when working on the gpu, however some torch modules will raise runtime errors, and the processing speed will be decreased.

generate_agent_instance_seed() → int ¶

generate_env_instance_seed() → int ¶

Generate env instance seed for seeding a particular instance of the env.

static generate_seed_from_random_state(rng: numpy.random.RandomState) → int ¶

Method for generating a random seed from the given random number generator.
