Save PyGAD output

[zsbeheshti]

Dear all,

I am using PyGAD and I want to save its outputs. How can I do this?

Hi @zsbeheshti,

You can use the save() method to save the instance and then use the load() function to load it back.

This is an example.

import pygad
import numpy

function_inputs = [4,-2,3.5,5,-11,-4.7]
desired_output = 44

def fitness_func(ga_instance, solution, solution_idx):
    output = numpy.sum(solution*function_inputs)
    fitness = 1.0 / (numpy.abs(output - desired_output) + 0.000001)
    return fitness

ga_instance = pygad.GA(num_generations=10,
                       num_parents_mating=10,
                       sol_per_pop=20,
                       num_genes=len(function_inputs),
                       fitness_func=fitness_func,
                       suppress_warnings=True)

ga_instance.run()

# Saving the GA instance.
filename = 'genetic'
ga_instance.save(filename=filename)

# Loading the saved GA instance.
loaded_ga_instance = pygad.load(filename=filename)
loaded_ga_instance.plot_fitness()

Is there another way to save the output so that the saved output can be received and checked in the format of numbers, graphs, etc.?
