Python array visualizer for debugging

I'm working with image processing which means I'm doing operations on large matrices. I'm trying to debug which means I need to explore the elements, but it's a real pain doing it with print statements. Is there some kind of python plugin that will let me view arrays in a GUI for the purpose of debugging?

However, if you would like to display numpy array as an image, you can use OpenCV Image Viewer Plugin, which I've just released.

yes just use the python debugger and put a break point

or use something like q

$ easy_install q

import q
my_array = numpy.arange(1000)
q.d() #open a terminal where you have access to my_array

you will see something like below

Python console opened by q.d() in <some_module>
>>> print my_array[5]

you can also use pill to generate an image from the array (not sure if it will work right without tweaking)

>>> import Image
>>> img = Image.fromarray(my_array, 'RGB')
>>> img.save('test.png')
