'numpy.ndarray' object has no attribute 'values'

This error occurs when you try to access the 'values' attribute of a NumPy array object. However, NumPy arrays do not have a 'values' attribute, and this attribute is specific to Pandas DataFrames or Series.

If you are trying to access the data of a NumPy array, you can simply use the array variable name. For example:

import numpy as np

my_array = np.array([1, 2, 3, 4, 5])

print(my_array)

This will output:

[1 2 3 4 5]

If you are working with a Pandas DataFrame or Series, you can access the data using the 'values' attribute. For example:

import pandas as pd

my_dataframe = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})

print(my_dataframe.values)

This will output:

array([[1, 4],
       [2, 5],
       [3, 6]])

Make sure you are using the right object type and attribute name for your specific use case.
