Python 执行类时出现TypeError和AttributeError

我是python类的新手，对它们有基本的了解。我试图从卫星图像中提取特征，以便稍后使用机器学习进行作物类型识别。我正在使用一个名为

EOlearn

的库，这是我用来计算功能的代码片段：

我认为这是因为在构造函数（第49行）中有3个参数（2个元组，1个列表），而不是4个，所以Python无法读取第四个参数：“band c”

我认为这是因为在构造函数（第49行）中有3个参数（2个元组，1个列表）而不是4，因此Python无法读取第四个参数：“band c”

那么我如何解决这个问题呢？用逗号分隔每个参数，使其具有一个feature_name参数、一个band_a参数、一个band_b参数和一个band_c参数。PS:self不是要插入的参数。我尝试过了（查看编辑的帖子）它抛出了一个不同的错误。它说band_a（因此band_names.index（'B05'））是一个int，没有属性split，因为split是用于字符串的。注意类型。如果是这种情况，那么规范化的差异索引是什么（参见第二次编辑）成功了？那我怎么能解决这个问题呢？用逗号分隔每个参数，让一个参数代表feature_name，一个参数代表band_a，一个参数代表band_b，一个参数代表band_c。PS:self不是一个要注入的参数。我试过了（看看编辑过的帖子），它抛出了一个不同的错误。它说band_a（所以band_names.index（'B05'））是一个int，没有属性拆分，因为拆分是用于字符串的。请注意类型。如果是这种情况，那么规范化的差异索引（请参阅第二次编辑）的工作原理是什么？
