用numpy.ndarray类型作为index操作时,报错:IndexError:arrays used as indices must be of integer (or boolean) type,解决办法: 将numpy.ndarray对象加上: 要操作的array.astype('int64') astype的作用是修改array元素的类型。
IndexError: arrays used as indices must be of integer (or boolean) type 解决思路 索引错误:用作索引的数组必须是整数(或布尔)类型 解决方法 将 t#类型为numpy.ndarray 1. 改为 t.astype('int64') 1. 哈哈,大功告成!

这8个基本类型的Class对象可以通过java.lang.Boolean.TYPE,java.lang.Integer.TYPE等来访问,同样可以通过int.class,boolean.class等来访问. int.class与Integer.TYPE是等价的,但是与Integer.class是不相等的,int.class指的是int的Class对象,Integer.class是Integer的Class的类对象. ...
