TypeError: 'numpy.int32' object is not iterable

This error occurs when you try to iterate over an object that cannot be iterated. In this case, it seems like you are trying to iterate over a numpy "int32" object.

Here's an example of how this error can occur:

import numpy as np

x = np.int32(5)
for i in x:
    print(i)

In this example, we create a numpy "int32" object called "x" with a value of 5. Then, we try to iterate over "x" using a for loop. However, since "x" is an integer and not an iterable object, we get the "TypeError: 'numpy.int32' object is not iterable" error.

To fix this error, you will need to make sure that you are trying to iterate over an iterable object, such as a list or a numpy array. If you are unsure of what type of object you are working with, you can use the "type()" function to check.
