Yes, I can't use it either.

Having discovered that view() didn't work, I looked at scipy's website, in
the plotting tutorial, and found a solution using plt :
For more details have a look at :
and more particularly where they display an image of "Lena".
I use these plt functions inside ipython (launched with "-p scipy"), and
it works great.
I hope this helps !
