如果为1代表连续取,如果为2代表隔一个取一个,以此类推 2、实例 先使用slice()确定截取数据项的范围,然后再使用列表的[]操作形式取出指定范围的数据项。 li = ["A","B","C","D","E","F","G"]# 取出A# 释义:从0开始取,取1个,步长为0s = slice(0,1, None)print(li[s])# ['A'] 以上...
slice(0, 13184, None), slice(None, None, None)”这个键可能是由于数据结构的问题或者代码中的逻辑错误导致的。请检查相关代码,确保使用正确的键值对。 理解错误信息 (图片来源网络,侵删) 当你在Python中使用None作为日志记录或数据处理时,遇到“(slice(0, 13184, None), slice(None, None, None)) is an...
在执行Python语句 new_supp_rows[:,1]=-new_supp_rows[:,1] 时报错如下 KeyError:(slice(None,None,None),1) 解决方法是将语句改为 new_supp_rows.values[:,1]=-new_supp_rows.values[:,1]

训练过程中出现如下报错:TypeError: '(slice(0, 13184, None), slice(None, None, None))' is an invalid key出现该问题的可能原因如下:切分数据时,选择的数据不对。尝试如下代码:X = dataset.iloc[:,:-1].values在创建训练作业前,推荐您先使用
slice(1,10).indices(5) 等同于 slice(1:5:1) slice(-2,None,None).indices(6) 等同于 slice(4,6,1),处理负数索引 'ABCDEFGH'[-3:20:1] 字符串总共长度只有8,索引内stop为20,超出长度,负数为逆序索引,正序索引即为长度+负数索引,step不变,所以前面切片等同于'ABCDEFGH'[5:8:1] sequence对象...
