pyneat.reporting module¶

Additional reporters (on top of what are offered by NEAT-Python) that are triggered on particular events.

class pyneat.reporting.LogFileReporter(filename, log_level=20, show_species_detail=True)[source]¶

Bases: neat.reporting.BaseReporter

Write the same information as the StdOutReporter, but instead of printing to standard out, the outputs are written to a log file.

filename¶

The name of the log file to use.

Type:	str

log_level¶

The log level (either DEBUG, INFO, WARNING, ERROR, or CRITICAL). Note: All LogFileReporter logs are INFO level.

Type:	logging.level

show_species_detail¶

Whether to show detailed species information.

Type:	bool

generation¶

The current generation.

Type:	int

generation_start_time¶

The start time of the current generation.

Type:	int

generation_times¶

The length of time to complete each generation.

Type:	list

num_extinctions¶

The number of extinctions that have occurred.

Type:	int

complete_extinction()[source]¶: The log message to write after a complete extinction has occurred.

end_generation(config, population, species_set)[source]¶

The log message to write when a generation is ended.

Parameters:	config (CustomConfig) – The global configuration settings for the entire algorithm. population (dict) – The population of individuals. A dictionary of genome key, genome pairs. species_set (SpeciesSet) – The speciation scheme for dividing the population into species.

found_solution(config, generation, best)[source]¶: The log message to write after a solution has been found.

info(msg)[source]¶

Write a custom log message.

Parameters:	msg (str) – The log message to write.

post_evaluate(config, population, species, best_genome)[source]¶

The log message to write after evaluating the fitness of the population.

Parameters:	config (CustomConfig) – The global configuration settings for the entire algorithm. population (dict) – The population of individuals. A dictionary of genome key, genome pairs. species (SpeciesSet) – The speciation scheme for dividing the population into species. best_genome (Genome) – The best genome from the population.

species_stagnant(sid, species)[source]¶: The log message to write when a species has stagnated.

start_generation(generation)[source]¶

The log message to write when a generation is started.

Parameters:	generation (int) – The current generation number.
