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。
TypeError: list indices must be integers or slices, not str How can my count work ? First,array_lengthshould be an integer and not a string: array_length =len(array_dates) Second, yourforloop should be constructed usingrange: foriinrange(array_length):# Use `xrange` for python 2. ...
The NumPy "IndexError: arrays used as indices must be of integer (or boolean) type" occurs when you try to use an array containing non-integer or boolean values when indexing another array. To solve the error, use the astype() method to convert the type of the array elements to int...
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...
The function will try to iterate over theparent_idstring instead offile_listand it will expect to see the index as an integer pointing to the specific character in string and not an index which is a string (titleorid). This will lead to theTypeError: string indices must be integerserror....
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. ...
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...

The variable y will shadow the function y, I recommend to to change the name of your function
