我正在使用 NEAT 创建一个简单的游戏 AI。然而，我发现了一个问题，游戏窗口在从第0代过渡到第1代时只会打开和关闭，而实际上它一直重复第0代，所以我要求gpt修改它。当我运行修改后的代码时，我收到以下消息：

neat.activations.InvalidActivationFunction: No such activation function: 'sum'
游戏确实从第 0 代转移到第 1 代，但出现错误消息
"No such activation function: 'sum'"
发生了。但是，我从未在 config-feedfoword 或游戏代码中使用过“sum”，所以我想知道为什么会发生此错误。
这是GPT和config-feedforward.txt文件修改的代码：

为了解决这个问题，我检查了是否有任何包含 sum 的代码，并按照 GPT 的建议，即activation_default项是问题所在，我将其从activation_default = relu更改为sigmoid，但仍然出现“sum”错误。真正令人沮丧的是我根本没有使用过“总和”这个词。请帮助这个受苦的年轻开发者。
除了 sum 之外，你还可以使用 sigmoid、relu 或其他不同的方法来暴力破解，请查看 NEAT 的官方文档
