setting an array element with a sequence error (Programming computer vision in with python book)

Question

I just follow the exercise from the book called Programming computer vision in with python. I'm trying to execute the following code but it give me errors.

from PIL import Image 
from numpy import * 
from pylab import * 
import imtools 
import pca

# Uses dense pca codepath.
imlist = imtools.get_imlist('D:Programming computer vision with pythonBasic image handling and processingData1')

im = array(Image.open(imlist[0]))  #open one image to get size 

m,n = im.shape[0:2] # get the size of the images 

imcount = len(imlist) # get the number of images

# create matrix to store all flattened images
immatrix = array([array(Image.open(im)).flatten() for im in imlist], "f")

# perform PCA
V, S, immean = pca.pca(immatrix)

# show some images (mean and 7 first modes)
figure() 

gray() 

subplot(2, 4, 1) 

imshow(immean.reshape(m,n)) 

for i in range(7): 

    subplot(2, 4, i+2) 

    imshow(V[i].reshape(m,n))

show()

when i compile this code it gives me this error:

immatrix = array([array(Image.open(im)).flatten() for im in imlist], "f") ValueError: setting an array element with a sequence. 

What should I do?
