Python help

I am new to Python and have to use it for a college assignment.

I am trying to execute a section of code that will import a jpg image using PIL module and convert it to a numpy array.

I keep getting the issue of "IndexError: too many indices for array"

Been looking around on-line on how to fix this but none the wiser.

import numpy as np
import matplotlib.pylab as pyp

from PIL import Image
empire = np.array(Image.open('./empire.jpg'))
print empire.shape, empire.dtype
print empire [:2,:2]

pyp.figure('Empire State Building')
pyp.imshow(empire)
pyp.show()

IndexError Traceback (most recent call last)
<ipython-input-4-391414696018> in <module>()
6 empire = np.array(Image.open('./empire.jpg'))
7 print empire.shape, empire.dtype
----> 8 print empire [:2,:2]
9
10 pyp.figure('Empire State Building')

IndexError: too many indices for array
