我试图学习使用整洁的python库（https://neat-python.readthedocs.io/en/latest/config_file.html），因此我正在关注本教程（https://www.youtube.com/watch?v=MMxFDaIOHsE&list=PLzMcBGfZo4-lwGZWXz5Qgta_YNX3_vLS2）。但是，在运行完成的代码后，出现错误“ TypeError：start_generation（）缺少1个必需的位置参数：'generation'”。底部完全错误。我已经完全按照所示重写了该行代码，但是仍然出现错误。有人可以帮忙吗？代码附在下面。

答案 0 :(得分：0)
我不知道您是否找到错误，但是可能在此行中：
stats = neat.StatisticsReporter
应该是这样的：
stats = neat.StatisticsReporter()
