Numpy error when creating GIF using images2gif.py

I'm trying to create a GIF file using images2fig.py from the visvis package

With this very simple code

import glob
from PIL import Image
from visvis.vvmovie.images2gif import writeGif

images = [Image.open(image) for image in glob.glob("*.png")]
filename = "test.gif"
writeGif(filename, images, duration=0.2)

I got an error

    writeGif(filename, images, duration=0.2)
  File "C:\Python27\lib\site-packages\visvis\vvmovie\images2gif.py", line 570, in writeGif
    images = gifWriter.convertImagesToPIL(images, dither, nq)
  File "C:\Python27\lib\site-packages\visvis\vvmovie\images2gif.py", line 373, in convertImagesToPIL
    im = Image.fromarray(im,'RGB')
  File "C:\Python27\lib\site-packages\PIL\Image.py", line 1937, in fromarray
    obj = obj.tobytes()
AttributeError: 'numpy.ndarray' object has no attribute 'tobytes'

What did I do wrong? How do I fix this?

I'm using Python 2.7.5, PIL 2.0.0-1, numpy 1.7.1-2, all are standard installation from Python(x,y) 2.7.5, and visvis 1.8 which is the latest version.

This looks like Pillow bug#224.

From what I can tell, the bug was introduced in 2.0.0 and fixed in 2.1.0 (checked in 21 May 2013). So, you should be able to fix it just by upgrading Pillow.

(If you're using a very old version of numpy, or Python 3.x, or a pre-2.0 Pillow (or PIL), this is not your bug. But none of those apply to you.)
