operands could not be broadcast together with shapes (4184,5) (4184,)

This error message indicates that there is an issue with broadcasting the shapes of two arrays. In this case, one array has a shape of (4184, 5) and the other has a shape of (4184).

To perform broadcasting, the dimensions of the arrays need to be compatible. In this case, the second array should have a shape of (4184, 1) to match the first array's shape of (4184, 5).

To fix this issue, you can reshape the second array by adding an additional dimension using the `np.newaxis` keyword. Here's an example:

import numpy as np

array1 = np.random.rand(4184, 5)
array2 = np.random.rand(4184)

# Reshape array2 to (4184, 1)
array2_reshaped = array2[:, np.newaxis]

# Perform the desired operation
result = array1 + array2_reshaped

By reshaping `array2` to have a shape of (4184, 1), it becomes compatible for broadcasting with `array1`.
