Description
I am using this example which is provided in documetation , but it gives me an error of parents , it said parents selected are not
numpy array, I am using the updated version of pygad
def parent_selection_func(fitness, num_parents, ga_instance):
fitness_sorted = sorted(range(len(fitness)), key=lambda k: fitness[k])
fitness_sorted.reverse()
parents = numpy.empty((num_parents, ga_instance.population.shape[1]))
for parent_num in range(num_parents):
parents[parent_num, :] = ga_instance.population[fitness_sorted[parent_num], :].copy()
return parents, fitness_sorted[:num_parents]`
