setting an array element with a sequence. The requested array would exceed the maximum number of dimension of 1.

This error occurs when you try to set an element in an array using a sequence, but the resulting array would have more than one dimension. In other words, you are trying to create a multi-dimensional array using a single index.

For example, consider the following code:

arr = [1, 2, 3]
arr[0:2] = [4, 5]

In this case, we are trying to set the first two elements of the array `arr` to the values `[4, 5]`. However, this would create a new array with two dimensions, which is not allowed in Python.

To fix this error, you need to make sure that the sequence you are using to set the array elements has the same dimensionality as the array itself. If you want to create a multi-dimensional array, you need to use nested lists or other data structures specifically designed for that purpose.
