我正在尝试使用NEAT通过音乐理论来生成歌曲。我已经在这里列出了基础代码，并且目前计划扩展一些功能。我的代码如下所示，同时附上了我的配置文件：然而，每当我尝试使用我的配置文件时，它要么返回一个运行时错误，提示缺少配置项：num_inputs，要么如果我尝试使用默认基因组配置，它会返回属性错误：模块 ‘neat’ 没有属性 ‘DefaultGenomeConfig’。任何建议都会非常有帮助。非常感谢您的提前帮助

将网络配置（num_inputs, num_outputs）移动到 [DefaultGenome] 部分（不是 DefaultGenomeConig）。
例如：
[NEAT]fitness_criterion = maxfitness_threshold = 3.9[DefaultGenome]# 网络参数num_hidden = 0num_inputs = 2num_outputs = 1Python-NEAT 需要在正确的部分找到这些参数。DefaultGenomeConfig 是对应于 DefaultGenome 部分的配置类名称。我认为这是混淆的来源。
这里有不错的文档：https://neat-python.readthedocs.io/en/latest/config_file.html
