TypeError: 'numpy.ndarray' object is not callable

This error occurs when you try to call a numpy array as if it were a function. For example:

import numpy as np

my_array = np.array([1, 2, 3])
result = my_array(2)

In this example, we are trying to call the numpy array `my_array` with the argument `2`. However, numpy arrays are not callable, and attempting to call them will result in a TypeError.

To fix this error, we need to use the correct syntax for accessing elements of a numpy array:

import numpy as np

my_array = np.array([1, 2, 3])
result = my_array[2]

Here, we use square brackets to access the third element (index 2) of the numpy array.
