Overload of constructor

[psosmol]

Hello, I have for files AllOnesGA.py with the main(), GeneticAlgorithm.py,Population.py and Individual.py

The cuestion is that pycharm mark as an error the overloading of the constructor
thanks

class Population:
    def __init__(self,populationSize):
        self.populationSize=individual_file[populationSize]
    def __init__(self,populationSize,chromosomeLength):
        self.population = individual_file.Individual[populationSize]
        for individualCount in range (0,populationSize):
            individual = individual_file(chromosomeLength)
            self.population[individualCount]= individual
        ...

what I'm doing wrong

ps:the error is

Error:
 File "/home/psm/PycharmProjects/AllOnesGA/genetic_algorithm.py", line 12, in initPopulation
    population = population_file.Population(self.populationSize, chromosomeLength)
