IndexError: too many indices for array: array is 0-dimensional, but 1 were indexed

This error occurs when you try to access an element of an array using too many indices. The error message indicates that the array is 0-dimensional, meaning it has no shape or size, but you are trying to access it as if it has one dimension.

For example, if you have an array `a` that is 0-dimensional, you cannot access its elements using an index:

a = np.array(10)
a[0] # Raises IndexError: too many indices for array

To fix this error, you need to make sure you are accessing the array with the correct number of indices based on its shape. If the array is 0-dimensional, you can access its value directly without using an index.
