df_output是一个pandas的dataframe,用iloc获取其中特定的一行 我之前一直以为啊,序号左边一列,就是写着1,2,3...那一列就是数值的index啊!在做了类似下面这样的操作以后,这个数值index就……就tm不再是纯纯的数值index了 index_duplicated_entry=self.duplicated_entry_indexes(identifier_columns)self.df_output.dr...
在数据预处理过程中,出现:IndexError: single positional indexer is out-of-bounds 原因是在使用 Pandas 读取 dataframe 的时候,分隔符搞错了!!! 这个时候,定点Debug一下,看一下切分出来的数据片格式 即可,
IndexError: single positional indexer is out-of-bounds 新建的数据框, 只有列名,然后传入数据的时候出错,查看数据框,没有一行,所以建立的数据框是有问题的。 这就是为什么会报越界的错误, 修正数据框,如下。 这样再赋值,就可以解决上述问题。
