numpy.ndarray' object has no attribute 'head'

`numpy.ndarray` doesn't have a `head()` attribute because it is not a pandas DataFrame or Series. The `head()` method is specific to pandas data structures, allowing you to preview the first few rows of the data.

If you want to see the contents of a numpy array, you can simply print it or access its elements directly using indexing. For example:

import numpy as np

arr = np.array([1, 2, 3, 4, 5])
print(arr)   # prints the entire array

# Accessing individual elements
print(arr[0])   # prints the first element

# Accessing a range of elements
print(arr[:3])   # prints the first three elements
