How to fix: AttributeError: module 'neat' has no attribute 'config'

Question

I am running through the guide for an AI that plays flappy bird using the NEAT neural network API found here.

When I run his code downloaded from Github, it gives me the error:

 "Traceback (most recent call last):
  File "test.py", line 438, in <module>
    run(config_path)
  File "test.py", line 412, in run
    config = neat.config.Config(neat.DefaultGenome, neat.DefaultReproduction,
AttributeError: module 'neat' has no attribute 'config'

The problem seems to be coming from this block of code:

def run(config_file):
    """
    runs the NEAT algorithm to train a neural network to play flappy bird.
    :param config_file: location of config file
    :return: None
    """
    config = neat.config.Config(neat.DefaultGenome, neat.DefaultReproduction,
                         neat.DefaultSpeciesSet, neat.DefaultStagnation,
                         config_file)

    # Create the population, which is the top-level object for a NEAT run.
    p = neat.Population(config)

    # Add a stdout reporter to show progress in the terminal.
    p.add_reporter(neat.StdOutReporter(True))
    stats = neat.StatisticsReporter()
    p.add_reporter(stats)
    #p.add_reporter(neat.Checkpointer(5))

    # Run for up to 50 generations.
    winner = p.run(eval_genomes, 50)

    # show final stats
    print('\nBest genome:\n{!s}'.format(winner))


if __name__ == '__main__':
    # Determine path to configuration file. This path manipulation is
    # here so that the script will run successfully regardless of the
    # current working directory.
    local_dir = os.path.dirname(__file__)
    config_path = os.path.join(local_dir, 'config-feedforward.txt')
    run(config_path)

However I looked in the Neat documentation found here and it says that this attribute does in fact exist. I'm using Pycharm on a mac if that is relevant. Does anyone know where the error coming from?

Answer 1

I've got the same problem on the same system.

Here is how I solved it:

open PyCharms Preferences,

goto "Project: NAME_OF_PROJECT",

then open "Project Interpreter",

in there uninstall "neat" by clicking the minus button

then click the plus button and search for "neat-python" and install that.

I think PyCharms automatic Interpreter installation method gets something wrong here and installs the wrong "neat" :-P Hope this works for you!
