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。
The error “Python error: list indices must be integers or slices, not a tuple” is caused when the user tries to access the elements of an array but places a comma in between the index values instead of a colon. To avoid this error, the user can access separate elements by using sepa...
All the characters of a string have aunique index. This index specifies the position of each character of the string. TypeError:string indices must be integersmeans an attempt to access a location within a string using an index that is not an integer. In the above case using the str[hello...

Hi Guys, thanks for creating this amazing library. I'm using XGBoost Classifier in sklearn library, and I'm getting this error, because my target column is numpy.float64 type though I only have 1.0 and 0.0 as a binary target. if we casca...
Useastype()to SolveIndexError: arrays used as indices must be of integer (or boolean) typein Numpy Numpy only works with two types, Integer or Boolean. Therefore, if there is a type it doesn’t understand, it will throw an error. ...
I am training a neural network. When I execute this code in MATLAB software, it goes very smoothly. However, when I convert it to an exe for execution, I encounter this error when outputting "Array indices must be positive integers or logical values", but my output value must have...
MATLAB sees that you're trying to index into an array. Array indices must be real positive (nonzero) integers (or logicals). So:would

You will get the “tuple indices must be integers or slices, not str” error message. This is because the index ‘0’ is a string, not an integer. Common Causes of the Error There are multiple common causes of the error when working with tuples: ...
