IndexError: index -4 is out of bounds for dimension 1 with size 3

这个错误通常发生在尝试访问一个不存在的索引元素时。例如,如果一个列表只有3个元素,但你尝试访问第4个元素,就会出现这个错误。
为了解决这个问题,你需要检查用于访问列表、数组或其他数据结构的索引值是否超出了其范围。请注意,Python中的索引值是从0开始的,因此访问第一个元素时索引值应为0,访问第二个元素时索引值为1,以此类推。

运行pad填充函数出现IndexError: index -4 is out of bounds for dimension 1 with size 3
这个错误通常表示你的输入数据与填充长度不匹配,导致填充时超出了输入数据的长度范围。你可以检查一下输入数据的维度和填充长度是否正确,并且确认填充方向是否正确。
另外,有些情况下,当填充长度小于输入数据长度时,也会出现这个错误。你可以尝试调整填充长度,或者在填充之前对输入数据进行截断。

IndexError: index 4 is out of bounds for dimension 1 with size 3
This error message indicates that you are trying to access an element in an array or list using an index that is outside the range of valid indices for that array or list. In this case, the array or list has a size of 3 in the second dimension, but you are trying to access an element at index 4, which is out of bounds.
For example, if you have an array like this:
```python
my_array = [[1,2,3],[4,5,6],[7,8,9]]
```
And you try to access an element using an out-of-bounds index like this:
```python
print(my_array[1][4])
```
You will get the IndexError message:
```
IndexError: index 4 is out of bounds for dimension 1 with size 3
```
To fix this error, make sure that you are using valid indices when accessing elements in your arrays or lists.
